Nor flash (MT25QU256ABA) in Imx8mp_evk protection error

Hi,

Hope you are all well.

I want to read/write nor flash memory (MT25QU256ABA) in imx8mp_evk board. I can access all configuration registers and read memory but when I write to the nor flash memory It seems that It is not applied and when I check the flag status register I get 0x92 according to datasheet it seems that it is a protection error.

I run enable_write in the first step and I have also checked:

nonvolatile lock bit --> unlock,

volatile lock bit --> unlock,

Hold and WP pins --> High,

Global free bit --> unlock.

I didn't change anything in Protection Security Register and its value is 0xFF

Can anyone tell me how I can solve the problem?

Best Regards,

Majid.
