Das U-Boot boot from JMB582

[hakotani-o]

I tried building Das U-Boot.
If writing to SPI Flash fails, Opi5 may not be able to boot, so I tried reading Das U-Boot from SD-CARD and experimenting to see if I could boot ubuntu rockchip or Armbian from the 2.5 inch SSD connected to JMB582.
As a result, ubuntu rockchip server, desktop, and Armbian 24.11.2 Noble Gnome successfully booted.
I was happy that it worked well.
Attached is the build script for Das U-Boot and the script to write to the SD-CARD using the USB converter.

This is exciting, thanks for putting together. Hopefully 6.13 will be released this weekend.

Thank you for your interest.

There are many things to look forward to, such as the completion level of the 6.13kernel and whether RK3688 and Snapdragon development boards will be sold ???.
By the way, it seems that there are also miniPCs like the one below.

Thank you.
