[SOLVED] memtest86+ on ODROID-H2/H2+

[roarking]

How do I run memtest86+ on ODROID-H2/H2+?

So far I tried booting from different USB media, e.g. Debian 10, Ubuntu 20.04.2 or grml. But without success. Where memtest86+ is offered in the Grub menu, it does not start when selected. I guess this has to do with H2/H2+ being a UEFI system.

Memtest86+ does not work in UEFI mode, as described here:

But MemTest86 works in UEFI mode:
