Hello U-Boot team,

We are facing a problem with our NOR Memory.

We try to update the content of this memory, the process is normally:

* Reset the target memory address range => back to 0xFF * Flash the new data * done

But, we noticed that the memory is not fully erased. The first block of 64KiB is reset and the next 64KiB block not, etc..

I join a log that presents our problem (erase NOR half.txt), the U-Boot config (u-boot.cfg) and the datasheet of the concerned memory (MX25U25645GMI00.pdf).

About our config:

* software development based on the DENX U-Boot V2019.10 revision * custom board with the CPU NXP LS1043a Layerscape * exact memory reference 'Macronix MX25U25645GMI00/TR' connected on a QSPI interface * We don't have any trouble to flash this memory with a Lauterbach debugger

Is this problem already known ?

Could you provide us a patch ?

If needed, I can transmit more information.

Mit freundlichen Grüßen Florian Manoël
