    Default Can't read 28F400 flash with TL866CS

    Like topic says...

    I have two chips. Both 29F800 and 28F400.

    One is Intel AB28F400 B5B and other is AMD AM29F800BB. In both case, when I select the proper chip in MiniPro and put the proper adapter (yes I have adapter.... SOP44 on top of TSOP48), it just says chip ID FFFF FFFF and says can't read.

    I have a willem SOP44 adapter on order, but it wont get here until next two weeks.

    Is there something wrong with my mini pro?

    I had the same problem several times.
    Cleaning the legs always helped.
    If you can't write disable "device id". Write a file than activate back "device id" and read and write again to be sure is not corrupt.

    You have a bad contact between the chip and the programmer. Try pressing your finger down on the chip.
    IF I HELPED YOU, PRESS THANKS AND REPUTATION BUTTON!!!
