Thanks

I have a CH341 programmer, but it is not listed when I search for my BIOS chip. Then, I tried to use detect with no results. I manually searched XMC XM25RH128CHIN chip doesn't appear in the list. I used CH341 2.2 version/ NEO Prog and AS programmer, but non of the programmers has this chip in the listing

Thank you for the reply
I downloaded the app ASProgramme 2.1.2, and as per your Picture attachment,t I can see the chip in the listing, but the software ASProgramme won't recognise it. My CH341(black), so it won't work, but I know that the programmer CH341 does work fine

Advice from the expert will be much appreciated.

Are you using an adapter board or a clip.

[Unique1234]

I took out the bios chip and mounted it on the board In the SOP board, I can read all CH341, NEO prog, but won't recognise it in AS PROG 2.1.2
