alchemist got a reaction from gprovost in Recovery: (too) short delay between UMS and Maskrom modes
yeah, but the feeling is less than 2 seconds. Can it because the flashing starts after the message (no lit, then lit)?
Meanwhile, I have my custom kernel and OS (Gentoo Linux), they run fine :-)

I will then boot from SPI NOR flash. The boot order is OK, I can then boot a "system rescue" from USB, or run armbian on sd as fall-back.
I can run Gentoo with one binary linked on the wiki page you pointed out, empty environment, and a minimal boot.scr on SATA
