Hi!

 

I have trouble flashing Winbond W25Q64 BIOS chip using Rpi. Can you please advise?

 

Output from the verbose log:

 

pi@raspberrypi:~/Temp $ sudo flashrom -p linux_spi:dev=/dev/spidev0.0,spispeed=2000 -w V3ZCAM10.BIN -V

flashrom  on Linux 4.19.66-v7l+ (armv7l)

flashrom is free software, get the source code at https://flashrom.org

 

flashrom was built with libpci 3.5.2, GCC 8.2.0, little endian

Command line (5 args): flashrom -p linux_spi:dev=/dev/spidev0.0,spispeed=2000 -w V3ZCAM10.BIN -V

Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).

Initializing linux_spi programmer

Using device /dev/spidev0.0

Using 2000 kHz clock

The following protocols are supported: SPI.

 

Found Winbond flash chip "W25Q64.W" (8192 kB, SPI) on linux_spi.

Chip status register is 0x00.

 

Found Winbond flash chip "W25Q64.W" (8192 kB, SPI).

This chip may contain one-time programmable memory. flashrom cannot read

and may never be able to write it, hence it may not be able to completely

clone the contents of this chip (see man page for details).

Reading old flash chip contents... done.

Uh oh. Erase/write failed. Checking if anything has changed.

Apparently at least some data has changed.

Your flash chip is in an unknown state.
