Hello, 

 

Is such configuration possible:

1. Orange Pi Zero + 

2. SPI-boot with no USB storage

3. SD Card has armbian files, but it is not bootable.

 

I red that there is configuration with SPI-boot + USB storage, but not sure if there is a guide/possibility to continue use SD Card.

 

Is that possible, is there any guide? 

 

Thank you.

SDCard has the priority in the boot process, so why do you want to use SPI-Boot ?

 

I want to have my SDCard storage fully encrypted including /etc and /home  so it can be used with particular OrangePI Zero board.

 

USB drive is not an option for me, so I thought for SPI-boot with some storage keys for SDCard. 

Even if your rootfs is encrypted, it doesn't prevent to leave the u-boot on the sd-card as usual.

BTW, I doubt that current Armbian u-boot is encryption aware, you will need custom build ...

 

You dont want uboot on the SD, it has higher priority than the spi so the spi boot hook will never get triggered with a valid uboot on the sd.

 

The way I did this with an Allwinner board with an A25Q128FV 128Mbit chip was to put the kernel with an embedded rootfs onto the spi. Boot spi kernel+rootfs image, decrypt sd, change root, continue sd boot process. I used buildroot to create the kernel+rootfs image which was about 9MB.

Thank you for answers guys. It seems I understand now the way I should explore.
