Hi. Do all of those 8-pin SPI NOR flash chips found in motherboards always have the same pinouts?
I have an MSI B350 Tomahawk with a Ryzen processor. The BIOS was version 1.20. We couldn't get the RAM to run anywhere near what it was supposed to run at (3200 MHz). The CPU, motherboard, and RAM came as a packaged deal from Newegg. The newest BIOS is 1.90 I belive and says it fixes memory compatibility issues. We were just enabling XMP and it wouldn't POST. We tried updating the BIOS through the UEFIs BIOS update program.
It wouldn't post at all after that. Just a black screen. I guess this is a common issue with these boards and these processors.
Anyway, my spi programmer shows the MISO and MOSI pins switched compared to what the data sheet says. Would that matter? I would like to think all these 25xx flashes share a standard pinouts. There's only one BIOS on this board.
This board has the 2x6 JSPI1 header and I have the pinouts for it. I can dump it and reprogram it in circuit. Just not sure if that really mattered or not.
Thanks.
