CH341 and W25Q80DV

[Philip Zahariev]

Hello,

I try to program W25Q80DV, but have issues. Before programming I read contents of chip, but file is not look to me good. Unfortunately I not pay enough attention on this fact. After unsuccessful first programming read chip again and contents of file was changed. After that I carefully check connection and found that some connection was not good. Attach probe one more time and have success on erase operation, but not on write. Currently chip is full with “FF”, but every try for writhing give me error. Exact chip model is Winbond 25Q80DVSIG and chip is soldered on Gigabyte GC-Titan Ridge board. I’m using image-assembling-programmer.png for programming. 
Strange for me is result for command
> flashrom -p ch341a_spi -c W25Q80.V

flashrom v1.2 on Darwin 20.6.0 (x86_64)
flashrom is free software, get the source code at https://flashrom.org

Calibrating delay loop... OK.
No EEPROM/flash device found.
Note: flashrom can never write if the flash chip isn't found automatically.

But if I try command
> flashrom -p ch341a_spi

flashrom v1.2 on Darwin 20.6.0 (x86_64)
flashrom is free software, get the source code at https://flashrom.org

Calibrating delay loop... OK.
Found Winbond flash chip "W25Q80.V" (1024 kB, SPI) on ch341a_spi.
No operations were specified.

Version of software was from today and compiled with "brew install flashrom” under MacOS Monterey 11.6.8

I’m waiting for your advice how to proceed further.
Best regards
Philip
