MX29GL128F chip erase fails, but autodetecting (and reading) works OK with clip ?


New Member
Hi guys,

I have a small board here with a flash chip MX29GL128F.
Using a clip it is correctly detected and reading is also OK, however chip erase doesn't work.

The WP# pin is pulled-up to 3v3.

Any idea what could be causing this ?
I haven't tried it in a TSOP56 socket yet but I will do so when my MX29GL128F parts will arrive.

It seems all sectors were protected!
Now erasing/writing works fine after unlocking all sectors.


You should share your modification with the developer, so this can be added to the general release.

Yeah maybe so .. he's free to contact me about details, or anybody else for that matter.

I think you're making too much fuss over this.
Just look at any of those flash's datasheets and it clearly says how to unlock a sector if locked.
If the developer is interested in adding such code he can do it more quickly and cleanly than I can.

Please close this topic now.
