840 G2 Macronix (MXIC) MX25L12873F Read Write Issues

Sorry not sure if this is the right section for this.

840 G2 Macronix (MXIC) MX25L12873F Issue with flashrom on Raspberry Pi or TL866II Plus with Xgpro.

I have no problem reading and writing and using hpunlocker with WinBond chips.

When I try the Macronix MX25L12873F then flashrom would be unable to detect the chip and Xgpro would fail the verify right away when trying to write back.

I also noticed the Xgpro is getting Device ID differences as shown in screenshots:

When autodetecting the chip I see Device ID: C2 20 18.

When I do a Read Device ID I get Device ID: C0 00 08

When I go to write the chip I get: ID error! Wish to continue programming, please cancel [Check device ID] option!

I tried getting some info from eevblog but it wasn't helpful.

I have tried this with chip on board and removed from board with the same issue. Could there be problem with the Xgpro database or other problem? I assume others have reprogrammed this chip model. I wish they would have kept the winbond chips as it has been super easy to work with.

Thanks for any help - I really appreciate the good people on this forum.

Hi,
I've the same programmer and using the socket sometimes I face the near same problem (ID sometimes is read and sometimes not).
Have you tried soldering the chip instead to use the socket? (if the chip is good the problem gone for me)
PS: I know this is an old post but if you solved the problem it could be useful to add some info.
