How To Flash NOR-Flash MX25U128 From MXIC

OP #6866761 
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

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.

They dropped the support on Bristol Ridge, which your AMD A6 9500 belongs to. You need to get back to old bios.
