Suddenly it does not work to flash Carprog with J-Link


I have flashed my Carprog more than 10 times without a problem.
And I do exactly the same now, but get this error . (see picture)
Nothing 's changed , I 've just opened Carprog to look for errors.


I have searched the internet for hours for answers but find nothing , so now I need your help.
Shall I give up and order a new one from China , but it will take at least 3 weeks before coming to Sweden so I would prefer
to find a solution for fault

I think your device is not erase correctly

[Youneselm]

Connect vdd to vlcdin on the device

If the usb does not recognize carprog if it means that a reset successfully passed ??
After resetting the H-jtag does not recognize my processor.
programmer I made resistors who has already been used for this procedure, what I'm doing wrong?

[FxShaw]

I agree I don't think you erase processor.

Good Luck.

Sometimes 12v adaptor is required to be plugged in to erase these

I had the same problem.

solution: when you erase MCU connect JTAG and run Detect MCU on H-JTAG

Hi friend do you solve this problem i have same on one

[tango]

you can erase the mcu with jlink
do the erase steps then when you connect jlink click erase and it will erase it for you
then reprogram it with the firmware you require

[4key]

I had the same. I changed soft in the J-Link (clone) for 4.96 and it went from hand.

[tango]

out of curiousity, how are people erasing the at88?
the erase and reprogramming of the mcu doesnt effect this chip so how is it getting wiped?

Hi friend do you solve this problem i have same on one

Excuse me for the late reply.
I gave up after all the various attempts, and soldered a new AT91SAM7S256 then everything worked as it should again.


The benefit was that it was easy to lift pin 55 before I soldered.
So I do not know why it was wrong, but that was all I did to get it working again.

Does this turn your car prog into a full version?

Think I am late to the party, I do have a jtag.
