[PATCH] dummy programmer: blacklist SPI commands
by Carl-Daniel Hailfinger 08 Feb '12

08 Feb '12

Add optional SPI command blacklisting to the flash chip emulator in the dummy programmer. Usage: flashrom -p dummy:spi_blacklist=hexstring If hexstring is 0302, flashrom will blacklist command 0x03 (READ) and command 0x02 (WRITE). The hexstring can have up to 521 bytes (256 commands) length, and must not start with 0x. TODO: Should 0x at the beginning of hexstring be tolerated? Very useful for testing corner cases if you don't own a locked down Intel chipset and want to simulate such a thing.

Hello Elena, Carl-Daniel had the impression that you did just a non-writing run with flashrom (i.e. calling flashrom without any of the -w and -E parameters). It seems that you have done more permanent harm and we need to know more details to be able to help (if at all). What hardware/laptop are we talking about? Which version of flashrom did you use (which distribution? Which command line arguments did you use? Can you remember any error messages it showed when you ran it? -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Please remove the power cable and battery from your laptop, wait 1 hour, then plug in battery and power cable and switch on your laptop again. That should work. Regards, Carl-Daniel
