S29GL01GP chip erase operation

wanglijian · ‎May 25, 2022

hello!

I am trying to erase the chip according to the chip sheet. my program is like the picture which is the same as the sheet example. However, when the erase operation is over, I read the data in a section of address and found that it is not 0xfff. the result is attached on. I don't know what the problem is. I hope you can help me.

Hello,

If you got 0xFFFF, that means the address is erased. And yes, it may take 6 minutes or more to erase whole chip in S29GL01GP (datasheet says 512s in typical, it’s 8 minutes).

The reason we generally not use simple delay is that the erase/program time varies by condition like temperature and/or number of erase performed.

Not sure why you got ‘7’ as returned status. Recommending to check “actual_data” directly.

Thank you

Regards,

Bushra
