AT25SL128A went into protected sector statePosted by ArunH 97 points 8 replies
I have a design based on AT25SL128A. I started with the standardflash.c and tests for it from the Adesto github website and all tests pass. So I assume my SPI integration is fine on my MCU.
I then set it running for a longer test so that it would keep writing/reading back data and then wrap around to the start of memory. Then I erase the 4K sector to reclaim it for writing.
However when I read back data after the wrap followed by 4K erase, I found I was always reading all 0s. Further check revealed that Status Register 1 value was 0xFC which means all the protect bits were set to 1.
Q1: This was not done by me, so I am wondering if you have any suggestions on whether the flash might go into this state on its own due to any trigger?
Q2: Or can it only happen if the MCU wrote this value to it?
Note1: I was able to recover back to working state by writing a new value to Status Register 1 but I want to check how to avoid this in the future.
Note2: Status Register 2 was 0x00, which is the default value. It did not change.
