No R44 vid mod instructions for 508/510

[Crazy1_79]

Skinerd gave me a quick how to for this a few weeks ago and I was amazed at the ease of this. No pulling board no cutting races. very simple and very quick
I use a spdt switch,
remove R44, it is located between two tsops U6 and U7 careful to not pull pads off
solder a wire on both pads, the pad closest to CPU goes to one side of switch
The pad closest to U7 goes to middle leg of switch
other end of switch gets 12v, you can find this on seperate Poweer supply board, it is well labeled. where black connector for pins are, one is labeled 12v
Jumper OJ1
Also the top 5 jtag points for the receiver.
Switch has to be set so pads of R44 are connected. detect in Jkeys. goto flash proammer select flash 1, then turn on Vid mod by flipping switch. now erase flash. (This will erase both flashes)
turn off vidmod and select flash 2
Turn vid mod back on
Now you can program your bin into receiver.
If you do not have vidmod in off position when you select flash jkeys will not recognize flash codes returned. Select flash then turn on vidmod. this method worked very well for me and skinerds said he uses it on all 508/510 regardless of having that one resistor or not.

This was the ONLY way to do a modified 501 I got whose board did not allow for any other way.

Skinerd has helped soooooo many. He the MAN!

edited and added the red part.

Wow! amazing, I was just about ask what is the latest and safest method for vidmodding a 508 or 510. I have read a lot of different post but most are dated a bit. I have both units and will have to give it a whirl. Thanks.

[Crazy1_79]

HA thanks skinerd, that is definately important.

[HoNEyDip]

Is it true that this R44 mod only works for AMD 323GT chips and not the ST 320Dt chips?
If so what is the recommended method for the ST 320DT chips?

[ogtigers]

Thanks Crazy and Skinerd, after many hours of reading you two helped me figure out how to jtag my 508. Confirm R44 mod works for 323GT :)

[Alviz]

And it's cool to hit WE# with straight 12V? The other stickied thread seemed to lean towards a 9V source.

What he said ain't it?? 12v right off the power supply header is what I use too.

No, will not work with ST 320DT chips.

Use the 4 wire 2 cut method, pull board, etc, for those.

Yeah, that's what he said. Can't hurt to 2x check. 12v from the board it is!

[hanoon]

what if you already tried the 4 wire 2 cut vidmod method and didn't work,,do I have to restore the cut 2 tracks to try this method?

[no_bser]

R44 method with a spdt is truly the easiest method of vidmod there is. (323GT chipset only)

But when did anyone say the easiest is the "best" way.

No way, the R44 method is by far the easiest.........I can pull R44 and put a switch in it's place and wire in a temp jtag in a 10 mins or less. (323GT only)

Of course you will have to repair the traces.......but why didn'tt it work, I use that mehtod for all permanent mods in a 510. Use a DPDT switch and include OJ on the other pole and never a problem, (except courese you forget to cut a trace :) which I have done.)

[eric keri]

Trying to do the NO R44 vid mod.. I removed the r44 and hooked up the switch with 12v from the power connector. I have the jtag hook up but when I open jkeys it shows some of the info but it not everything..This is what I get!

IRD# R -0 0000 00001-96
box keys FF FF FF FF FF FF FF FF
Boot strap XXXX.

Everything else is there..

And Im trying to get a card I popped to work with this DVR 510. What do i have to do...
I normally only mess with married subed's...


O YEA when Im done do i have to put that R44 chip back on the borad????

Open tsop in "Moved Ird Info" instead of "Moved Bootstrap". R44 is 0 ohm resistor so just short the pads when finished!

Hi, I am doing the 1st 510 R44 and got the same message on jkey as eric keri and there was a response from workmen, but I dont understand what it mean and how to correct it and get all the IRD and Box Keys info..The receiver has no card, Thank you very much

[airzimzerker]

I have only done the GT chips so I am wondering why the vid mod does not work with the DT chips. The datasheet descriptions is almost exactly the same. Is there different supporting circuitry? Here is how to unlock the DT from the datasheet.

When VPP/Write Protect is raised to VPP the memory automatically enters the Unlock Bypass mode. When VPP/Write Protect returns to VIH or VIL normal
operation resumes. During Unlock Bypass Program operations the memory draws IPP from the pin to supply the programming circuits. See the description of the Unlock Bypass command in the Command Interface section. The transitions from
VIH to VPP and from VPP to VIH must be slower than tVHVPP, see Figure 15.

Never raise VPP/Write Protect to VPP from any mode except Read mode, otherwise the memory may be left in an indeterminate state. A 0.1μF capacitor should be connected between the VPP/Write Protect pin and the VSS Ground pin
to decouple the current surges from the power supply. The PCB track widths must be sufficient to carry the currents required during Unlock Bypass Program, IPP.

Reset/Block Temporary Unprotect (RP). The Reset/Block Temporary Unprotect pin can be used to apply a Hardware Reset to the memory or to temporarily unprotect all Blocks that have been protected. Note that if VPP/WP is at VIL, then the 16 KByte outermost boot block will remain protect even if RP is at VID. A Hardware Reset is achieved by holding Reset/ Block Temporary Unprotect Low, VIL, for at least tPLPX. After Reset/Block Temporary Unprotect goes High, VIH, the memory will be ready for Bus Read and Bus Write operations after tPHEL or tRHEL, whichever occurs last. See the Ready/Busy Output section, Table 15 and Figure 14, Reset/ Temporary Unprotect AC Characteristics for more details. Holding RP at VID will temporarily unprotect the protected Blocks in the memory. Program and Erase operations on all blocks will be possible. The transition from VIH to VID must be slower than
tPHPHH.

I do have 323GT chips on the 510

I do not have an ird with those. I was asking a question. If the data sheet says that is the way the part works then it works that way. This is why I asked about the circuity. I would like to understand why it does not work.

It's a mystery to me as to why the 320DT U7 TSOP requires the 3 wire 1 cut vidmod and the R44 vidmod does NOT work on this chip, but these are the facts.

[airzimzerker]

the difference in datasheet descriptions is that the 320dt must not rise to 12V faster than 250ms and it needs a 0.1uF bypass cap. This vid mod might work with just the 0.1 uF cap or an rc circuit with a time constant greater then 250 ns.

[bored2def36]

im wanting to try this r44 mod, but my question is, exactly where is oj1?

Look for a little silver tower (I don't remember what kind of electronic part it is) in the middle of the IRD's motherboard. You will need to remove the 40-pin hard drive cable from the motherboard in order to see it clearly, more than likely. Once you find it, ground the square pad of OJ1.

Thanks Lizard.
I have two 510's i been dying to do since i got them, but never could figure out where the darn oj1 was.
Guess i was blind in one eye and couldnt see out the other..
Its basically right there around all the jtag solder points.
thanks guys this has been really helpful :)

That is a crystal. And you can jump the round and square pads of OJ1 together, as the round pad IS ground.

[The Lizard King]

That is a crystal.
What's the function of a "crystal"?

And you can jump the round and square pads of OJ1 together, as the round pad IS ground.
This I know. However, I find it easier to ground the square pad of OJ1 to the IRD's metal chassis with an alligator clip.

Is actually a "crystal oscillator", crystal is used for short.

It generates a repetitive signal, usually incorporated to make a square wave, used as a clock signal for example.

Hi Guys,
With all the how 2 out there,........Iam still mistyfied about the different
wires running here and there on the diagrams.......My 510 is a 323GT board
and i see some diagram have trace cut underneath the board..........
My question is can i just do mine without the tracecut underneath?............
I already remove R44, put switch in, and solder jtag in.....12v from powersupply board.............Can i do it NO R44 VIDMOD without trace cut underneath board................please say I CAN........
All Help is greatly apreciated

Thanks in advance
eliang

[airzimzerker]

You are mixing the 2 methods. Only 1 is valid and this depends on the chipset. It has been a while so I do not remenber which chips the R44 mod works with. If it works with your chipset then only do that mod which is all topside. If it does not work with your chipset you have to do the cut trace bottom side vid mod. Do not do both.

[eliang]

Hi Airzimzerker..........sounds positive, i will live with dat bro.....u look like u kno u stuff..
I want to thank u for pointing me in the right direction.........
I apreciate that very well.............
keep up the good vibes...............happy testing..............


Thanks in advance

[elperro]

This is exactly what I was looking for....I am going to try my first 510. thanks mods for the excellent work.

Did you read the whole thread, including the VERY FIRST POST?? It has your answer.

[midgetcoach]

opened a 508 to jtag it as per on the pic from this post. Went to solder the TRST (green) and... no resister in that spot. Enlarged the pic to be sure and double checked the board. All other jtag locations are as should but not that one. Any ideas. My Board has DT chips.

Does this board have a regular JTAG port over near the power supply?

[midgetcoach]

Yes it does have a port. I have soldered a buffered jtag to it but it is not getting a real good read. I wanted to solder it to the board and see if I can get a better read. Can't seem to find any pic or info to solder a jtag directly to this board. Two 323DT chips, it should not need the V mod to read it.

[vdee]

you may not be getting a good read because of a lack of ground..make sure you're using the R79 pad for ground

[midgetcoach]

Ok I'll solder a ground down to the board and see if it helps. Also stopped and picked up some 100 O resisters for another jtag I have. Still can find any info on where to solder the led to from the missing resister on this board.

Heres the 508-510dvr top-side jtag points...

http://www.dssftp.com/forum/attachment.php?attachmentid=9390&d=1233006070

[midgetcoach]

OK here it is. I soldered down my buffered jtag and then tried my regular jtag to the jtag pads. Soldered the ground and still can't get a good read on the tsop. The picture of the top side jtag points doesn't match my board. I don't have the two far right jtag points at all on the board. It is a two chip 323DT board. Its a 508, but when I jtag it, it says its a 501 and has FFFFs on one of the blocks.
I have looked all over and can't find anything on the jtag points for this board. Anyone know where "workmen" is at?

[airzimzerker]

Make sure you have a correct jkeys deffinition for a 508. Might be 501 with moved info or something like that. You may also have to manually select that option.

[midgetcoach]

If I change it to 510 manually and press detect it still goes back to 501. There is not doubt that this is a 508 box. I think I need jtag locations for this board.

[airzimzerker]

If you are getting information than the jtag is connected correctly.

[midgetcoach]

Its connected on to the jtag pads now. When I select "detect" it goes to 501 and info is missing for the software and the build config has the last letter wrong. If I select 508 and press detect it jumps back to 501. If I select 510 and press select it reads the build config and the missing info is there but now no box numders or IRD number.
I looked at all the pic's I could find and non show this board being jtaged.
Remember I tried 2 jtags, one buffered one not, I know they are both good. Hoping for someone to see this who knows 5xx boards.

When you select 508, DON'T hit detect......all info should be correct, if you hit detect it will go back to a 501 everytime.

[midgetcoach]

Ok have it hooked back up right now. Plug it in open Jkeys and it read 501. IRD #s and Box #s are right. Build config has a wrong number at the end and bootstrap is XXXX's. Change model to 508 and Jkeys displays IRD as 000000's and Box as XXXXXXX's, other information is correct. Note, this receiver has an SO card with it. If I hook up the receiver it boots and everything loads. Gets all the nfree dish stuff and I can get all the system info from it.
I downloaded the tsops and tried to read them but they are curpted.
