Good evening all,

After heaving sweated for months, I finally call for help at the community...

My target is to program several SPI chips in order to repare some ASUS laptops, which was solved before by purchasing pre-programmed BIOS Chips

I first tried to access with an SOIC "gripper" clip, directly on the chip being soldered on the main board.

Facing to a lot of failures (unknown chip), I decided than to work on de-soldered chips.

This allowed me to extract some dumps on failing and fresh purchased SPIs.

Now, I have a satisfying database of complete images of BIOS, that I expect to use for programming new chips according each need.

At that point begin my problem :

After a abort during the first trial, I decided to erase my chip, and got the following advise :

"C:\Flashrom>flashrom -E -p buspirate_spi:dev=/COM3,spispeed=1M
flashrom v0.9.6.1-r1704 on Windows 6.1 (x86)
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OK.
Found Winbond flash chip "W25Q32.V" (4096 kB, SPI) on buspirate_spi.
Erasing and writing flash chip... FAILED at 0x00000800! Expected=0xff, Found=0x00, failed byte count from 0x00000000-0x00000fff: 0x600
ERASE FAILED!
Reading current flash chip contents..."

Than I decided to purchase a DIP to SOIC adaptor in order to eliminate my doubts on the connection by gripper. Now the chips I use are soldered ...

I tried to write again the BIOS image and got the following after a very long time of writing operation (more than one hour) and using the following command :

"flashrom -w flash.bin -VVV -p buspirate_spi:dev=/COM3,spispeed=1M"

The reslult is :

"Your flash chip is in an unknown state.
Please report this on IRC at chat.freenode.net (channel #flashrom) or
mail flashrom@flashrom.org, thanks!
buspirate_sendrecv: write 1, read 0 Sending 0x00

buspirate_sendrecv: write 0, read 1 , receiving 0x31

Considering than I took every possible care on the connection between Buspirate and SPI, and having a satisfying reading result (dumps are checked with Hex Editor and look OK), I am stucked at that point...

I would appreciate any support from you.

Thanks !
