AW: [EXT] Issue with saveenv() and the QSPI NOR memory MICRON MT25QU01GBBB

Fri Jan 24 09:30:14 CET 2020

Hi Kuldeep,

After bringing my local U-Boot to the v2020.01, applied your series of patch and do the necessary modifications. Our U-Boot is now correctly working with the QSPI NOR Flash.
Even better, it's now compatible with the 2 variants of our board (32MiB <=> 128MiB QSPI NOR Flash) without any particular modification.
Of course, we still need to perform more test but it is already looking better than before.

Thanks for your support and your reactivity.

Regards,
Florian

Mit freundlichen Grüßen

Please apply patch series [1] on top of denx tree.
Please let me know in case of any failure.
