Can I program a W25Q80DV in circuit?
« on: Today at 08:38:41 am »
Hi,

I have a device (a FNIRSI SG04 process calibrator) that does not start anymore after a failed firmware upgrade.

Obviously the code is stored in a W25Q80DC chip from winbond in an accessible SOIC8 form factor. I have different firmware revisions as a .bin file.

Does anyone know if it´s possible to flash this device with a SOIC8-test-clip in circuit? Can anyone recommend a tool or Raspi-code or anything else to flash via SPI?

I´d desolder the chip only as a measure of last resort. The SG04 has quite a lot of analogue blocks and I don't want to thermally stress them if it´s not the only alternative to discarding.

Thanks in advance!
Every time you think you designed something foolproof, the universe catches up and designs a greater fool.
