Hello Forum long story short, yesterday i bricked my Mini-PC while flashing the BIOS. Now I have learned that an MXIC (MX25U12873F) 1.8V, 128M-BIT [x 1/x 2/x 4] CMOS MXSMIO (SERIAL MULTI I/O) FLASH MEMORY is used to store the BIOS. I cant find any valuable information on how to flash the IC -the right- way. The IC is an 8-pin SOP soldered on board. I have the image file but no clue to flash the IC. I whish to reprogram the IC using the BIOS image provided, in hopes to revive the mini-pc. The manufacturers data-sheet can be found here: https://www.mxic.com.tw/en-us/products/NOR-Flash/Serial-NOR-Flash/Pages/spec.aspx?p=MX25U12873F&m=Serial%20NOR%20Flash&n=PM2348#Technical-Documents I tried hard on ebay and amazon to find a suitable Serial EEPROM & FLASH PROGRAMMER for this specific IC from MXIC but im not sure which programmer is to pick. any help appreciated thanks in advance Andreas

That's a rather standard SPI flash, so almost all programmers available for SPI flash devices will do - except it's 1.8V only, so you have to look for a programmer supporting that supply level. Another option is to get a Nucleo-Board with 1.8V option like Nucleo-H7A3ZI-Q, -H723ZG, -H743ZI2, jumper it to VDD 1.8V and use to use OpenOCD with QSPI driver (built in on recent versions) or with patch https://review.openocd.org/c/openocd/+/4760. The main obstacle in both cases is to remove the chip from the mainboard, attach it to the programmer (by a test socket) and later solder it to the mainboard again. That's not trivial if you don't have some experience in (de-) soldering. To program it on the mainboard is possible theoretically but requires some precautions (keeping the mainboard's connections in high-impedance state etc.) So, it boild downs to this rather mechanical issue ... Do you have any experience regarding that? If not, the question regarding a programmer is rather pointless, I'm afraid.
