Can't erase flash EEPROM

[micoanjo]

When I try to flash my card i get a error Failed to enter program mode... error erasing flash/ EEPROM I am new at this type of card i ustto have the rev 247 and looped it so i went back to this card till i deside to go to fta air or get a new card any help would be welcomed thanks in advanced

[AOAOAO]

Is this the first time you tried this on this particular computer? If your talking atmega is it jumper or jumperless. Like dvd said above a little more info and we can help.

[micoanjo]

i am using a desktop pc with xp pro... the card is a atmega 128 .... r1 25 pin comunacation cable porgramer i never played with this type of card was doing lots of reading as i said i was using the rev 247 hope this helps i am so stuck tryed everything i can out of opctions thx i am using jeepers

[AOAOAO]

Try booting to the BIOS and changing the pararell port setting to ECP or ECP/EPP.

[alsouthster]

do you have the pfg in the same folder as Jeepers?
will get that error if not

[micoanjo]

thanks will try ECP

[micoanjo]

I have tryed all i can think of i can't read the card either i went and bought a new 25 pin cable... the Atmega 128 card is a jumperless card I know there is something stupid i am doing or not doing.... i Have the update pfg file ... I think it won't be too long and it will be a new rev cardlol but i am not giving up on this

[alsouthster]

check this troubleshooting C&p, posted it earlier today in another thread, may help


C&P

Failed to enter program mode means that there is no comunication between the computer and the atmega.

Assuming the atmega is working then the problem is in the interfase between the pc and the atmega, so there are a lot of posible things wrong.

1.- bad contact between the atmega pads and socket pins.
2.- bad or wrong type cable from pc to programmer.
3.- wrong type of programmer for that atmega.
4.- wrong pc port selected in Jeepers/ file/preferences, the standard parallel port should be in address 0378.
5.- wrong type of parallel port selected in pc bios, try to change to SPP type.
6.- inspect the pins of the chip for trace of dirt or corrosion, clean with a brush.
7.- inspect atmega jumper for false contact.
8.- low voltage from parallel port, try the usb mod.

i have the same problem flashing atmega card. mine was working fine until it froze up . and when i flashed again i got the message failed to enter program mode. then it says full write complete. i checked my cable, cleaned pins. checked everthing i could . i have 2 programmers and 2 cards and both are doing the same.

thanks

If it's a jumperless look for 2 holes labled J1 to the left of the XTAL by P5 and C1. Use a paperclip to jump them and try to erase it again. After you sucessfully do this a few times it should program with out the jump in place.

[alsouthster]

you checked in Jeepers/ file/preferences that it's at 0378?

[bocker59]

mine is at 0378 in preferences

[alsouthster]

hmmm I dunno
in bios you tried SPP? and ECP?
could try what AO is saying, never tried that personally but who knows
you have tried different pfgs? different version of jeepers?
arrrgh lock fuse bits?

[AOAOAO]

If this looks like yours this is what I'm trying to explain. Jump these 2 points. Also check your Lock Fuse settings--Atmel-Atmega 128-lock/fuse settings. They should look like the one pictured.

[bocker59]

nope mine is differnt

[AOAOAO]

What about the lock/fuse settings? Post a pic of the atmega too.

[bocker59]

stupid question but where do i find lock fuse settings?//

[AOAOAO]

Look at my post #15

[bocker59]

how do i check fuse/ lock settings?? sorry for the hastle

[bocker59]

not a good pic in first one sorry

[micoanjo]

I am having the same problem bocker i've done everything now except a nother new cable that is my last step.....but I do have to say all the help and info is so much appr... the guys here go beond to help thanks to all who have given info.... I see by your pic your card is the same as mine and you have the ssame problem..????? hummmmm

[AOAOAO]

These atmegas you guys have can be programed without jumpers but did originally come with them. So when they get locked up try this: Jump the first 2 pins the one on the edge and the middle one and try to erase the flash, your programmer looks good bocker59. Read my post above^^^ #15 it shows and tells how to check your fuse/lock. When you get into it follow the picture for the settings and hit write then read to make sure they changed. Ps you guys must be running D*lls so if you do the bios setting like I stated earlier you should be good. I'm going to get some glasses now thanks to your pics.:)

[bocker59]

wont allow me to ck fuse/lock settings still getting message failed to enter program mode, and yes the guys helping here do a great job and r to be applauded for their support and help of guys like us who dont know a lot on the subjects refered to
great job keep up the awsome work and sorry for the pics hope yer eyes get better lol

[alsouthster]

did you try jumping it like AO suggested?
here's another explanation of the procedure, C&P, may help
again, never tried this personally but supposedly it works

C&P

Unlocking Atmega

Take the board out of the programmer & ground pin 1 (PEN - Programming Enable) of Atmega128 to pin 63. This will FORCE the chip into the SRI programming mode.

To put it a simply,
- Place atmega in a way that the dimple on the atmel chip is in the top right corner.
- Now get some very fine insulated copper wire hold one end of it onto pin 1 (first pin above dimple on chip) and place other end to GND pin 63 (second pin down on set of vertical pins to the right).
- Hold it for about 5-10 seconds with card out of programmer.
- Now put card in programmer, repeat above steps.
- After 10 seconds keeping jumper wire in place hit full monty, BUT KEEP THE WIRE IN PLACE THROUGHOUT THE ENTIRE PROGRAMMING PROCESS! Let it write.
- Bingo! ... You have restored the eeprom, flash, proper fuse/lock bits....everything will be perfect!

Bocker and Micoanjo! What are you guys having for dinner? Would you like me to make a house call? Are there any available women there? Let me know I'll be right over. Take your time I'm sure if you re-trace your steps you'll get it. Don't forget to post back.

[alsouthster]

lol
make sure there is liquor there too ;)

[micoanjo]

I would like to thank alsouthster and AOAOAO I got my card up and running thanks ... and yes come to dinner anytime I am sure we can find you what ever ya are looking for.... Thanks so much you guys ROCK>>>> I guess i should tell you the problemwas I bought a new 25 pin cable never thought it would be that but I followed all youguys steps and it just seemed to me it wasn't comunicating with the programer... so I went out and got another new cable ant man that was all it was go figure.... Thanks again,... I love this...

[AOAOAO]

Great to hear that Take care!

[bocker59]

im stillworkin on my cards , no luck yet but as they say patience my ass im gonna kill something . .glad to hear your up and running micoanjo. graet job guys

[AOAOAO]

Bocker have you tried programing with a different computer?

[bocker59]

gonna try using my bros puter today, and try his cables and programmer

[AOAOAO]

Make sure you bring your cable and programer along too.

[bocker59]

ive tried 2 different cablles, a different programmer, and diff computer and still cant get passed failed to enter program mode on both of my cards.
maybe new card is in order i guess.thanks for everything

[bored2def36]

Bocker,

I've had this problem a few times with one of my atmegas, what worked for me was going up to the top in jeepers and clicking the atmel / atmega128 selection and going to erase flash / eeprom, i do that like 3 times.
Also i do the alternative chip erase and then it seems to work.

Hope that might help you some also.

[bocker59]

aaaaaaarrrrrrrrrrrrrrrrrrrggggggggggggggggggggghhh hhhhhhhhhhhhhhhhhhhh
ok im fine now but heres the deal. i flashed my atmega 128
i hit write
it wrote a bit then stopped half way through
i hit write again and got failed to enter program mode
i tried again and again and again
i hit erase flash but that wont work
i hit alt erase and that worked
i hit erase flash again and still get error
i tried 2 new cables
i tried a different programmer
i tried a different computer
i tried to check fuse lock settings but it wont let me in
now heres the question
DOES ANYONE HAVE A HAMMER???????
anyways thanks for all the help im gonna watch barney on cable

[bocker59]

did i mention i was using bev??merci'

[bocker59]

i mean bell //////ohhhh boy barney got me all upset

[AOAOAO]

If you got half a write and you were able to erase then the problem might be that you are running to many programs in the background. Relax your almost there. Close some programs like messengers and your virus scan, anything open on top of you clock and try again. Remember to erase it 3x's before attemting a re-write.

[bocker59]

thanks AO i'll give it a try again and again and again lol

[bocker59]

tried my atmega in my friends programmer tonite and still the same results.is it possible my atmega is looped or locked and if so how do i unlock it. on card has 3 pins on it the other has 10

[AOAOAO]

I thought you said you got it to erase once? Try the same senarial to erase it jump the pins and if it erases jump then keep it jumped to program it. You can also look for the "Original Junior Roba" program or "Atmega Restore" which is the same program under another name to put it back to factory settings.

[bocker59]

just found my jumper pin for atmega card put it on erased flash hit full monty, hit get keys,hit write put it in reciever and it worked .go figger huh
anyways thanks to e1 who helped ,and thanks AO for your time

[AOAOAO]

Glad to see you got it working. Good Job!

[bocker59]

im so happy no more barney yessssssssssssssss

[bocker59]

thanks to you AO great job now i can get back to a normal life for awhile lol tv mmmmmmmm

[sailor]

Micoanjo, where did you get your 25 pin cable. I need to get one asap. Do you have store, part # and cost? Thanks, Sailor.

[robm661]

i had a similar problem ,icoreected it bya simple alternate chiperase then went to the reg erase flash eeprom erase after no problems,i dont know if u tried that its might work

[micoanjo]

sorry sailor been away for some time ... it is a regular 25 pin male to male data transfer cable I got it at Staples $20:00

[sailor]

Thanks M, I'll give staples a try...
