Unsupported chip

[tom.healthcliff]

Hello,

I'm trying to read memory from "Boya Microelectronics" 25D16ASSIG chip. This chip seems to be unsuported so I would like to add support for it. Could you explain me how to find out manufacturer and device ID?

Best,
Tom

Hi,

either by looking at the output of flashrom -V or into the data sheet.
Since you usually need more information than just the IDs the latter is
very much preferred. With some variation of the chip marking and
educated guessing one can easily find it:

No idea how current the docs in the wiki are but have a look at:

Hi,

Thanks for your help, I was able to read the memory from this chip.
Vendor ID 0x68, device ID 0x4015.

Kind regards
