Flashrom & Serprog Question
by egeebt00＠gmail.com 02 Mar '21

Hello again. Posted this question in irc, but had to disconnect, thats why i ask here. I build Urja Rannikko's atmega644 programmer and used it with flashrom 0.9.9 on windows. If i do not connect a flash chip (only parallel flash chips here to test) to the programmer i get the messages that bus mode parallel and spi are on (lpc and hw off). When i connect a SST39VF040 to the programmer and execute flashrom the parallel mode is changed to off, so only spi is on. Can i force the programmer / flashrom to check only for flash chips in parallel mode (with a parameter e.g.)? I did notice, that i had the wrong jumper position set for the flash chip (5V instead of 3,3V). Is it possible that this is the reason why flashrom switches to spi? I'm pretty sure that the flash chip is dead now, but i have two more of this type :). Hope someone can help.

Hallow, Thanks for your work (flashrom). In hardware list there is w25q32, but mine is BV. Flashrom can not detect my chip. Is it not supported or i am doing something wrong? I wired like example in tutorial. I have arduino mega2560. What i can do? Thanks for help. With Best Regards Aurimas ⁣Get BlueMail for Android

Verifying flash failed

Hi, I have successfully erased and write the chip but it cannot verify it. When I try to boot it it doesn't even boot, fan spin on for a second and then off. I am flashing my t440p. I hope I have given you enough information. Thanks, Nathaniel

Error on Yuna
by Flynn Price 02 Mar '21

Hi, can you please see the error below? Am i safe to reboot? Previously it said the flash was in an unknown state and to not reboot. Thanks! Erasing and writing flash chip... 0x420000-0x427fff: EInvalid OPCODE 0x06, will not execute. spi_write_cmd failed during command execution at address 0x420000 ERASE_FAILED FAILED! Uh oh. Erase/write failed. Checking if anything changed. Reading current flash chip contents... 000000-0x7fffff:R done. Good, writing to the flash chip apparently didn't do anything. This means we have to add special support for your board, programmer or flash chip. Please report this on IRC at chat.freenode.net (channel #flashrom) or mail flashrom(a)flashrom.org, thanks!
