OPI Zero boot with SPI
Hi, I am trying to make the OPI Zero boot with the help of the onboard SPI with the goal to boot from an usb drive
and not from the sdcard.
What steps should be executed. I only managed to get the Xenial image to work with my 512Mb board... so that is what I want to use.
I assume... I need to make u-boot work with the sdcard... move the whole thing to the usb drive (with the u-boot)
and than populate somehow the SPI with the image of an SPL, which would get it up through the u-boot on the
First. Fot this kind of development and hacking serial console aka UART is mandatory. Nobody will want to play a guessing game if something doesn't work, so we need a boot log to figure out what happens during the boot process.
From here:
Assuming you booted a Xenial legacy image and installed flashrom (standard one from the Ubuntu repository)
Assuming you extracted a .deb file from here and put u-boot-sunxi-with-spl.bin in your home directory
Assuming SPI flash size is 16MBit
