Hi I have problems flashing mx25l4005 chip. I'm using raspberry pi for flashing. I have connected to is thru putty and i have compiled flashrom from latest stable release. There are flashrom log files that I have created. It looks like it doesn't recognize chip. I have connected chip using folowing rpi header name chip pin 1 3.3V 8 6 GND 4 19 DI 5 21 DO 2 23 SCK 6 24 CS 1 Any ideas on how to solve this? Kind regards Goran Metlic

Flashrom v0.9.6.1-r1564 BIOS reading fail on HP EliteBook 8560p
by Marc-Alexandre Espiaut 30 Nov '12

30 Nov '12

Here's the log you're asking for. I haven't installed dmidecode since it prevents flashrom from running on a laptop for security reasons. Replacing the current BIOS on this laptop would be a blast. HP/Compaq BIOS prevents the user to change the hardware to what they want. For exemple, replacing a Mini PCI-e Wifi card that requires proprietary drivers with one that can use FOSS drivers. Hope that helps, feel free to contact me for further informations about my laptop. Regards, Marc-Alexandre Espiaut

Can someone > help? flashrom does not care about the contents of the files you fed it at all, hence they must be prepared first. usually this is done by cutting out headers or footers. in the case of wph it is likely that you can cut everything away that is larger than your flash chip AFAIK. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Ok thanks for the info. In my case the BIOS file is smaller than the chip size. So I need to blow it up. Are there some information about that somewhere? I couldnt find anything?
