4100 Will Not Verify

[cnr0616]

I've got two 4100's, both with Intel TE28F160 chips. I have one working, and the other is not. If I backup the full flash on the working one, and flash the non working one the compare/verify function always fails. I have tried mutiple versions of a full dump other than mine with the same result.

If you notice the ERASE function seems too quick. I am using the USBJTAG NT.

Code: Select all

Could it just be a bad flash chip?

I would be interested to see this. Have not programmed the SB4100 for a long time. The erase is too quick. I will use read back function to see what is in the flash. BTW, which version of software do you use?

This makes no sense to me, but it does work in the UJModem 0.15 software. By clicking on load, and writing all, the erase takes a few seconds, which it should, then it correctly flashes the firmware.

Using USB JTAG NT 0.26 I got the results posted in the thread before.

OK I will try it tonight to see if there is a problem.

OK. I wonder how do you flash sb4100? does it flash as same as SB5100 ?
THANK YOU.

Purchase a USB JTAG NT from this site if you haven't already. Then start reading.

I just tested on SB4100 and here is the result.

Looks no problem to me.
If UJmodem works for you then use UJmodem for now.
