I'm trying to flash my Linksys WRT 310-N device and had no success yet. For some reason I put there wrong firmware and screwed device, after that I tried to flash it but EJTAG tool becomes frozen at the erasing step.
My flash chip is not detected automatically, so I'm using /fc option to specify it. I have EON EN29LV320AB-70TCP chip and I'm using EJTAG 3.0.1

Tjtag 3.0.1 is not capable of flashing your 320n, only 3.0.2 is, and its still a little buggy, I thnk I have found the problem with it and will post another RC3 today. Then you may be able to recover you router. _________________ Want JTAG support - Donate a router

Finally, I debricked my router using serial conenction and by pressing ctrl-c and then by uploading firmware using tftp. Thank you very much for your help and information. When I was connected to the correct jtag port I was able to backup cfe, did it 2 times and backup files were identical. Flash memory chip was automatically detected by the EJTAG tool (ver 3.0.1). Hovewer, I was unable to erase nvram and kernel, for some reason it stopped working and stopped detecting chip after second backup of cfe.

Just wondering about RC3 getting Device not connected error with RC2 and not with 3.0.1 so I'm connected right. Any help appreciated.
What router, processor and flash type? Tornado would need to know.
It's a wrt320n. He said in an earlier post that he's have RC3 back out in a couple of days and that it would help on the 320.
I got a 320 that is kicking my ass but I believe the flash chip is fubar.. The owner said he pin shorted. So I ordered a new chip. Hopefully it is either the chip or the utility. If neither, then the pin short took out the data lines in the processor. Then it is junk.
LOM used jtag on his 320 developing the e2000 port so it works (software). _________________ [Moderator Deleted]

Jtag3 works on this 320, but the chip isn't supported it's supported in RC2 which is telling me that I'm not connected or have the wrong cable etc. I've converted another 320 to a e2k and it works better that way, but my 160's still out perform it. _________________ E4200 w/ mega build 23838
Just to let you know I've developed a small mod to the old version 3.01 to better support Ti AR7 routers such as Linksys ADSL2MUE and Netgear DG834GV3. More details in a post over at RouterTech forums http://www.routertech.org/viewtopic.php?f=19&t=3732 - as they offer 3rd party firmware for these non-ddwrt ADSL routers, and hopefully they can support that specific hardware.
Appreciate probably too late for you to incorporate in 3.02, but it 'works for me', so I'll port to 3.02 if needed, as and when.
Same copy of the attachment here.
Note: There was one hardcode of the Broadcom FLASH_MEMORY_START address in chip_erase at line 2485 in tjtag.c - not sure if important but just commented it out for now...
