Caution: EXT Email
Hello U-Boot team,
I am Florian, working at Siemens in Germany.
I am in charge of bringing up a custom board based on the processor NXP QorIQ LS1043a.
So far, I have been able to bring U-Boot on the board without too much troubles.
However I can not get the command 'saveenv' to work. Our environment variables are stored in the QSPI NOR memory that is also used as boot memory.
The 'saveenv' command always ends up in a
Please apply patch series [1] on top of denx tree. Please let me know in case of any failure.

Saving Environment to SPI Flash... Erasing SPI flash...flash operation timed out

Few more information:
No issue with a Lauterbach debugger
I noticed that the NOR memory at offset address 0 get erased during the
operation. The normal offset of the env variable is normally 0x900000.
- The memory used is the 'MT25QU01GBBB' from MICRON (Device ID
0x20bb21). I can provide the datasheet.
- the NOR memory is correctly discovered, 'sf probe => SF: Detected n25q00a
with page size 256 Bytes, erase size 64 KiB, total 128 MiB'
- I have tried to activate the debug logs but they didn't bring any interesting
information.
