    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.

    https://www.eevblog.com/forum/projec...?topicseen#new

    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.

          Can't write on mxic mx25l640E with Ch341 (WSON package)
          by krissdmtz
          So i found something strange, i have a mac a1370, already took the dump from the mx25l640E, i dont have the adapter but i managed to solder it on a board adapter with cables



          I can read from it

          I can erase it (VERY SLOW THO)

          but cant write on it, am using CH341 3v (came modded from where i brought it)

          Also using NeoProgrammer 2.1.0.19

          What can i do?...

          bug of the month: write caching setting for the hard drive in device manager
          by ChaosLegionnaire
          i recently bought a new wd re4 2tb with 2014 datecodes. when i got around to testing it tho in victoria hd tester, the write speed was very slow at 14 mb/s with a 256 sector transfer size. when i increased the transfer size to 1024 sectors, the write speed increased slightly to 44 mb/s. read speeds and sector verify speeds were fine and at normal speeds.

          so i just ass-u-med the drive's poor performance was due to it being an advanced format drive and i was using it on winxp. when i tried cloning my system disk to this wd re4 2tb drive and writing to it in linux, the write speed...

          novice user attempting first BIOS write on ASUS laptop
          by alphabetty
          Hello first post!


          Ok so after an (ASUSTek) optional Windows update, my old ASUS E403NA laptop rebooted and froze in the BIOS menu screen and was unresponsive so after about 30 mins I powered off and back on again. Now i just get a power LED and a black screen, I have tried all the basic suggestions and all the suggestions on the ASUS site, spoke to ASUS support who said I will need to pay for an RMA.

          The laptop is worth €50 so I won't be doing the RMA at god knows what price.

          So I have seen some videos where people have reprogrammed the BIOS...
