Greetings. Please let me know if there is a better place to ask this
question.
Any clues here? I've got an AllWinner H5 with Winbond SPI flash attached on
SPI0. The flash is programmed using the sunxi FEL tools and boots perfectly.
Now I'd like to save the environment there too.
Loading Environment from SPI Flash...
Invalid bus 0 (err=-19)
*** Warning - spi_flash_probe_bus_cs() failed, using default environment
