Hello,
typing saveenv I get: Saving environment to SPI Flash... SF: Detected gd25lq32 with page size 256 Bytes, erase size 4 KiB, total 4 MiB Cannot set speed (err=-1) *** Warning - spi_flash_probe_bus_cs() failed, using defualt environment

and now environment is not saved and it seems it is indeed reset to default.
This is wrong on several levels
- storing evironment in flash is attempted when booted from mmc - it might make sense to read both media(os)-specific environment *and* device-specific environment but in absence of default mechanism to merge the two environment should primarily come from boot medium and the scripts on the boot medium may then load device-specific environment from medium-neutral device-specific storage. - when storing environment fails it is reset - the flash description is not sufficient for the flash driver to access the flash - I wonder how well thought out the storage mechanism is - the flash normally contains a partition table and with start of the flash readonly. There is probably a partition at the end that can be used for environment but u-boot clearly did not read that since it uses the default scripts.
I can do with using default environment and changing the disk layout to what u-boot expects but it would be nice if the environment actually worked.
Thanks
Michal
