Hello.From my side, I tried to flash my Asrock AB350 Pro 4 mainboard with that same chip -Winbond W25Q128.W- with Flashrom v1.1 build from source on a Rasberry PI 3B. It found the chip via the motherboard's SPI header pins succesfully. I could read it's into a bin file, but when I tried to erase/write it whit a new bios version (to update my bios for Ryzen 7 2700) it can't, cause the write protection. After this trying, I desoldered the chip from the board, and "installed" onto a breadboard with pull up resistorsfor /WP and /Hold and a 820 Ohm serie resistor with VCC and I connected a 0.22 uF capacitor beatwen the VCC and GND nearest to the chip. When I tried this setup, the Flashrom can read recognize the chip and read it's memory of course and when I tried to flas it with a new bios file from asrcok.com, It seems It can write into the chip...Flashrom had begun the Erase/write step, my Raspberry's CPU had a 25-32% system load...I thought it will be successful, but this writing erasing process has never end. I left my Pi system to working on it for hours, but never and. spispeed=2000. So now i ordered a CH341A programmer with 1.8 V SOIC8 adapter and I will trying with that. -------- Eredeti üzenet --------Feladó: Angel Pons th3fanbus@gmail.com Dátum: 2019. 07. 09. 16:18 (GMT+01:00) Címzett: prokudin prokudin@papillon.ru Másolatot kap: flashrom flashrom@flashrom.org Tárgy: [flashrom] Re: This flash part has status UNTESTED: sucsessfull write to W25Q128.W Hello,On Tue, Jul 9, 2019, 14:44 prokudin prokudin@papillon.ru wrote: Found Winbond flash chip "W25Q128.W" (16384 kB, SPI) mapped at physical address 0x00000000ff000000.Finding a 1.8V flash chip on such a mainboard is very strange. Can you check the flash chip installed on your mainboard, to see if it actually is that chip?I would also try flashrom from git, to see if it works. Looks like your distro's flashrom does not report the version.Best regards,Angel Pons
