Flashing bios failes Acer A315-34 XM25Q64 with TL866-III

[johnbeton]

Hello,

I have a Acer A315-34 that came in with no post. FN-ESC shows Tianocore logo, and with bios .fd file starts reading from usb, but system doesn't post afterwards either.
I read the original bios with my TL866-III reader with XGPRO with success.
Erase works but writing a new file always gives an error.
Any one have an idea what I can try next ?
This is the log from XGPRO

What are the full topside markings of the flash IC? Post a pic. Being detected as XM25Q64.

Check on the options for the SPI interface bus speed for this programmer. Slow it down and test again.

The vendor / mfr of this tool (we have their T56 unit) should be alerted on the same for assistance.

The top reading is XMC QU64AHIG.
I tried all speeds with no success (forgot to mention)

QU = 1.65~1.95V, 4KB uniform-sector, Quad Mode

Is this what the programmer is detecting?

I cannot find this information in XGPRO, you have any idea where I can find it ?

Which software version are you running? Is it 12.67? Mine just said this version is now available from the summer. The way they host their s/w is pure ghetto. Let me share my feedback with clarity. Have pop-ups galore on their shared drives. For a company that is printing money, the files should be hosted on a clean company server. Looks very poor on their part to send links to mediafire, etc. All we need is to get a virus while attempting to reflash a chip.

Managed to solve this problem.
I manually selected the IC and chose for XM25QU64B (pure guess because it's closest to XM25QU64A instead of automatic detection XM25Q64.
I unchecked the Check ID option and selected lowest SPI frequency (4.0mhz). Don't know if higher frequency would work also, but with these settings write / verify success.
Resolderd the chip and system works :-)

Good. Override their auto-detect.
