Update SPI on e25?

[Meestor_X]

I assume I should be using the MTD/SPI for u-boot on this device?

If so, how do I update it and choose the boot order?

 

armbian-install complains "No SPI image found." if I select "Install/Update the bootloader on MTD Flash"

see: https://radxa.com/products/network-computer/e25#techspec

Only SD-card for this device, hence boot order is something fixed, just hardware.

On software level it depends on how U-Boot it configured and compiled and on higher level, what partitions are found, can also be USB-stick, and what is on those partitions. Can be Armbian standard boot.scr or own extlinux or even EFI if you want. 

 

So minimum is SD-card with U-Boot on it, else nothing will happen unless maskROM is entered, see Radxa docs.

The e25 that I have has SD, eMMC and NVME storage options.

It has an MTD/SPI as well.

 

Pretty sure it's similar to the Cubie a5e where you can set the boot order in the SPI, however I just chatGPT'd the shit out of that one to get it sorted. I'd prefer to do it the "approved/armbian" way...

Again, I assume having U-Boot in the SPI is the appropriate way to do things so I can boot from any of these devices (and perhaps even external USB?). I'd like to understand how to do that if someone knows?

OK, so the URL I posted is not correct. If those devices are there, your only option is to use dd with correct offsets on SPI/MTD or eMMC ( or SD-card) to write a U-Boot binary.

An lsblk should show those devices, else maybe the armbian-install tool is likely correct with its error message.
