Jtag problems with 510

[reaven]

did you need to have your Hard disk connect to read box keys cause the only thing i get is unknown device


**or need to downgrade the harddisk first

[skinerd]

No, it will read boxkeys with or w/o HD installed.
Unless you are pretty fair at soldering, you will have a hard time getting a jtag correctly hooked to the 510 with no jtag port, and you risk damaging the board too.

[reaven]

am very good at soldering i have made several mod like an xbox and everything works fine but really dont know whats happening am using the 3 wires under and the 3 wires up the one " Phiberoptik " wrote !!

[reaven]

also did i need to have the smart card on it

[sfg]

What sort of jtag are you using? I could not get mine to work with my old dtv buffered jtag so I modded it into a simple jtag and it works great.

no you don't need the card in it.

Are you using the 301-508 jkeys?

sfg

[reaven]

what you mean the only thing i get is unknown device

[reaven]

am using the simple jtag for the 510 i think is pretty the same as 508

[sfg]

Not sure what you are asking here.

Ok. So what about the version of jkeys. Are you using the 301-508 jkeys?

Try the link posted on my sig. I think the one Phiberoptik originally posted had a wire crossed on it.

Yes it did, 4 & 13 were swaped, but the latest ones I have seen, that show only top side connection points works fine.

[reaven]

which one was it the lpt pin 4 and 13 on the top of the board i switch wire and still getting unknown device on jkeys 2.9.9 and jkeys 133

[reaven]

anyway to test connection like test point or something , i have the pin 13 closer to the capacitor is this the right one ?

[skinerd]

which one was it the lpt pin 4 and 13 on the top of the board i switch wire and still getting unknown device on jkeys 2.9.9 and jkeys 133

Attached is a pic showing the top side locations and OJ1 location.......

[reaven]

ok that pocture is from a 510 cause i dont have that resistor where is suppose to be the point for pin 5 neither the one for the pin 2 my connection for those point are under the board like the one Phiberoptik do in his guide !!!

men am going crazy here i even re do all points clean my contacts and short the wire like 6 inches !! let see if i can take a pic of my connection and board

Post a pic of your board showing the same part as the one I posted, lets compare......

reaven,

I am pretty sure you are using the wrong version of jkeys. you need to use the 301-508 version. Thats why I have been asking what version of jkeys you were using.

sfg

[reaven]

this are the connection i use for under the board

http://www.boomspeed.com/reaven/underboard.jpg


and this is the top of my board

[reaven]

reaven,

I am pretty sure you are using the wrong version of jkeys. you need to use the 301-508 version. Thats why I have been asking what version of jkeys you were using.

sfg

well the version am using is jkeys 133 and jkeys 2.9.9, where you get that version so i can try out !!

[skinerd]

well the version am using is jkeys 133 and jkeys 2.9.9, where you get that version so i can try out !!


Jkeys 301-508, from where you ask?.........................hmmmmmmmmmm,...the files section?????

[reaven]

can someone please tell me the specific location i mean the folder where the program is cause am against the download limit to search a lot of files in different folders , or if someone have another link for the file would be better !!

[reaven]

what about the mb picture i post , why is missing those 2 resistor from my mb ??

[skinerd]

what about the mb picture i post , why is missing those 2 resistor from my mb ??


That must be an earlier version of the 510..................

[reaven]

you wont believe this and corect me if am wrong are this the jtag pads ?? this actually my 510board

http://www.boomspeed.com/reaven/DSC00019.JPG


if so i can use the same instruction as for the 508

[sukh77]

u must have a 508 board in a 510 case. Lucky bastard if thats the case.

[reaven]

whats the procedure then ??

[sukh77]

http://www.bellexpress.vu/jtag_ht.html see if this helps. 508 should be same as 501.

[reaven]

really men i dont know what am doing wrong am using now the connection from the file inside the 301-508 jkeys file the one for the 508 and even so i get the unknown device

[reaven]

please help urgent help please please

[skinerd]

That is an older 510 board, use 508 jtagging info....easy to do........

Right above the red circle on your pic, pads 19 and 20 are labeled,

pads.....lpt
9.........2
11.......3
13.......4
15......13
19.......5
20.......ground.

[reaven]

exactly that how i did !!! when i found the jtag pads i disconnect the my previous attempt using the Phiberoptik method and use the method you post here easy soldering .






also am using the 301-508 jkeys and nothing just unknown device so

any special requirements like special parallel port setting, you already told me that i can read box keys w/wo the hard disk in , i need to have the smart card in or out , i need to conect the receiver direct to the pc or i can use and extension the jtag its only 6 inches , what else am telling you man am going crazy here been here like all weekend dont even get a good sleep!!


so please skinerd or sukh77 i know youre the one that know as far as i know !!! please please help me :cry: :cry:

[reaven]

this is my jtag cable

http://www.boomspeed.com/reaven/jtag_pad.JPG

[sukh77]

Have u tested any other ird on that PC or another words are u able to jtag other IRD's on this PC? You might try another PC. I don't have a 501 or 508 so not sure what u might be missing seems like the connections are all there.
Are u shorting the OJ1 connection when jtaging?

[reaven]

no, i need to short the oj1 to jtag

[skinerd]

no, i need to short the oj1 to jtag

NO.......you don't short OJ1 to the jtag...........OJ1 is 2 pads that get shorted together so the receiver boots into link mode or BFR, but that is not going to help with the detection problem, the OJ1 connection only helps with DCU peek errors.

A simple jtag like yours usually works if correctly connected, are you sure yours is??
I see your 25 pin connector, how does it connect to the PC?

Take a another pic where the wires connect to the board.
Looks like you used different colored wires so I can tell you if your connection is correct.

[reaven]

here we go again !!!

[skinerd]

Connection looks ok...........It's not perfectly clear, but I think good enough to tell.

You never said what kind of extension cable you are using??
Is it a serial/parallel extension cable?? 25 pin straight thru....????

[reaven]

well i check continuity and its straight
i also check continuity from the parallel conector to the board and everything was fine
am out of ideas !

and am not getting yet to the part of the hard disk get the hard disk down to 80gigs then married and erased the tsop address to flash another image to get the hard disk married to the receiver and ect.... you know !!!

[reaven]

any special requirements for the parallel port setting like specific address, mode (epp,ecp )

smart card in or out turn the reciever on first then fire up jkeys????

[skinerd]

Don't matter if receiver on or not, jump OJ1 together and it won't come on anyway.
AS long as the parallel port is bi-directional it should work, some people have reported they need to set it up to ECP or EPP, mine is on SPP and works fine for jtagging and MC programming. Just make sure jkeys is setup for parallel port and the address of the parallel port, usually 0x378 but not always.....

[reaven]

any other idea ???

[reaven]

this is incredible i cant jtag my receiver !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!

[skinerd]

this is incredible i cant jtag my receiver !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!

Does the jtag work on anothe receiver?? To verify the cable and jkeys are working.
Worse thing you can do is get frustrated.......find the problem and solve it....
I have jtagged hunders of receivers going back to DTV days......never a problem that could not be readily fixed........

[sfg]

you may have already done this stuff but I am just throwing ideas out there.

You said you checked continuity:

Did you check from the pins on the db5 connector or from the solder points?

Did you check the solder points to the board?

Did you check the jtag traces on the board to make sure they are intact?

Are you absolutely sure that the resitors are all 100ohms? (don't bite my head off, I know you checked)

Try another computer as sukh77 said.

make sure you read the posts carefully and post your results otherwise we don't know if you tried them.

It took me a month to get my 510 going so I know what you are going through but if you stick with it and be patient it will work.

sfg

[reaven]

well i think am on my way its been a week well i try everything post in this thread like ::

what i check !!!

* i check continuity in the 25 straigh thru extension cable
* continuity between board and connector
* resistor all 100ohm 1/4watt
* jtag cable no more than 6 1/2inch
* check solder point on the board (easy cause they are easy access and bigger )
* check on 2 different pc but with the same OS
* check jkeys version all 3 v. 133 v. 2.9.9 and v. 301-508
what i still need to check

* another computer with another OS
* when i solder the other method the one from Phiberoptik and under the board the pin # 3
when i took that wire the trace get lift a little (but i reconnect everything and the pvr works ok, record and every function its ok). dont know any test point to see if this have anything to do why i cant jtag from the jtag pads the one i found later on (see picture)

[skinerd]

Still have not read if the jtag works on another receiver or not?????????

[reaven]

i dont another receiver to jtag

[sukh77]

Well since u don't have another IRD you will have to try to jtag this on another pc or find another easy to jtag IRD and verify that u are able to jtag.

[skinerd]

sukh77 said it all.....you don't even know if you set up works, so don't blame the receiver, I jtag them all the time, normally use a buffered jtag tho....

the connections shown LOOK correct, but something is going on here.....have you tried to hook the jtag directly to the parallel port?? Is jkeys set for the correct parallel port??

[reaven]

i know i dont blame the receiver but is frustrating !!!well yes skinerd i check the parallel port address and check the jkeys parallel port address not the jinterface address i know thats not the one !!! as we speak am setup a pc with no other than win95 to see if an older OS works better at least only the parallel port and also i has connect the jtag direct to the port what about the traced i told before
when i solder the other method the one from Phiberoptik and under the board the pin # 3

The other trace prolly the problem, shoot a pic and post it, lets have a look, the jtag port has no bearing on the nornal operation of the PVR.

[reaven]

i will post th epic tomorow cause am using the receiver right now !! thanks for the help
anyway i will try first with the pc I setup with win95

[reaven]

already fix the trace try another pc with win95 with no luck

any idea

[skinerd]

already fix the trace try another pc with win95 with no luck

any idea


Post a pic..........I'll bet the trace is not fixed......

[reaven]

well i check continuity from the broken side to the jtag pad i think was #9 or #11 and everything was fine and also check continuity from the broken trace to where the trace end , thats where i fix the trace i make a jumper and everything was ok .. i can take a pic right now cause the camera doesnt have too much resolution to show that detail !!!!!

[reaven]

UPGRADE WIN95 TO WIN2000 same thing nothing !!!

[reaven]

this is how and where i fix the trace

http://www.boomspeed.com/reaven/trace_fix.jpg

[skinerd]

Ok, remove the wire, get some 30 gauge wire wrap wire and stick it through the hole where the trace ends, that's a thru hole and goes diectly under the CPU if that is not making good contact under the CPU you will never jtag it.

[reaven]

i think that wire is guage 30 !!! so i have to remove the wire then the old solder then stick the wire thru the hole and apply little solder or until melt thru the wire ?? my fear is let the iron too much time and mess something in the cpu and then i will no only be unable to jtag i will not be able even to use the receiver !!

[skinerd]

If it's 30 gauge, then it will slip into the hole at the end of that trace, I tried it......

[reaven]

i will try it thanks alot skinerd, sukh77, sfg and everyone thta help me in this forums you are the best !!!

BTW finally what vidmod is the best or work best cause a heard a lot about different vidmod that i dont know which really works !! and correct the following list of the things i have to do after i jtag the receiver

1. jtag the reciever
2. backup tsop
3. vidomoded (if i need too, this for sure need to vidmod right ?)
4. downsize hardisk

this where i get lost cause of the receiver married thing with the hard disk
that i have to delet some address i think u6 and/or u7 and upload another one to accept the 80gig HD!!

[reaven]

really i dont know what else to do !!! i try that skinerd and in efect i clean well the area and when i heat the wire with a little solder it slip thru the hole i finish the jumper everything ok
but i still cant jtag !!!!

##$^$%&^&%(&&!!!! am out of ideas am still have faith and hope but no ideas

[skinerd]

Until you can jtag it, there is NOTHING else you can do.......

I'll look at it if you want, shoot me a PM if interested.......if nescessary I can test continuity back to the CPU and solder directly to it if nescessary.

[reaven]

http://www.boomspeed.com/reaven/trace.jpg



am confused about pin #4 and pin #13 which one i have to jumper in the cpu 110 or 112

also now in jekys am getting in device id 0x8df477co

[skinerd]

That trace is very easy to repair, I have done several that were ripped up from the use of large wire,
Stick a piece of 30 ga wire about one inch through the board, trim it to fit where the trace was and solder it down.
Long wires are not your friend, jtag wires need to be kept short to avoid picking up interference.

[reaven]

ok i trim the wire now i have like 4inches of wire what device id 0xdb6c36db means

[reaven]

now all am getting is instead of 0xfffffffff am getting 0xfffffffe with an e at the last!!

and this is really getting to my nerve !!!

[skinerd]

ok i trim the wire now i have like 4inches of wire what device id 0xdb6c36db means

Either interference on the jtag lines or incompatible PC and or parallel port.
I use buffered jtags only but do on occasion see incompatability issues with ports and or PCs. Especially with laptop PCs, their parallel ports are a little different and can cause issues.

[reaven]

and what else can i do ???

[reaven]

now i only have th error 0x0000000 and i check continuity and i have continuyty with ground on all points this receiver is crazy !!

[skinerd]

now i only have th error 0x0000000 and i check continuity and i have continuyty with ground on all points this receiver is crazy !!

4 out of the 5 jtag leads should have about 10k ohms to ground continunity.
