I'm using this QSPI Flash on a couple of projects based on ST microcontrollers. I'm using this Flash to run hold my application code and some images.
I wrote my drivers. No problem for the first time. I can erase and write.
Then when I try to erase and program again it doesn't work anymore. It seems that this flash cannot be erased (I tried to erase single 4K sectors, 32K block and full chip).
This happening on 50% of the assembled memories. I'm really worried...
I'm attaching my driver.
Any idea? Please help!
Thank you very much in advance
