Failure using flashrom and BusPirate to flash Macronix MX25L3206E bios chip
Hello, I'm using flashrom via buspirate_spi to try and access the Macronix MX25L3206E bios chip on my Asus G73JW laptop. Here is the command line I'm using: flashrom.exe -p buspirate_spi:dev=com3,spispeed=1M Attached is more info on my laptop and the software I'm using, as well as the flashrom log. Regards, Matt
Hi, most probably a connection problem. See also http://flashrom.org/ISP and http://flashrom.org/Bus_Pirate -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner
Stefan, Thanks for your quick response. I did a little more work, and it looks like I needed to power the mainboard w/ the ac adapter to power the chip and disconnect vcc from bus pirate from pin 8. Then I enabled bus pirate's internal pullup resistors by connecting vcc to vpu. So this works now: C:\flashrom>*flashrom -p buspirate_spi:dev=com3,pullups=on,spispeed=8M* flashrom v0.9.6.1-r1704 on Windows 5.1 (x86) flashrom is free software, get the source code at http://www.flashrom.org Calibrating delay loop... OK. Found Macronix flash chip "MX25L3205(A)" (4096 kB, SPI) on buspirate_spi. Found Macronix flash chip "MX25L3205D/MX25L3208D" (4096 kB, SPI) on buspirate_spi. Found Macronix flash chip "MX25L3206E" (4096 kB, SPI) on buspirate_spi. Multiple flash chip definitions match the detected chip(s): "MX25L3205(A)", "MX25L3205D/MX25L3208D", "MX25L3206E" Please specify which chip definition to use with the -c <chipname> option. Thanks to everyone who works on flashrom, hopefully now I will be able to recover my bricked laptop by flashing a new bios. Regards, Matt On 2/22/2014 8:26 AM, Stefan Tauner wrote:
