Hello!
I have three Libre Computer Tritium H5 boards and three eMMC modules on hands. All three eMMC modules is flashed with exactly same Armbian image and exactly same uboot. I also use exactly same PSU and cable for all three boards (however I reproduced this issue with four PSU and three microUSB cables, no difference in behavior was found).
All three boards start just fine from microSD (so it's not exactly "Your board doesn't work?" case).
One board never boot from eMMC on first power up, but almost always boot on second power up. That reproducible with all three eMMC modules.
Two other boards just never boot from any eMMC module.
When board can not boot from eMMC it just stuck there:
U-Boot SPL 2021.04-armbian (May 06 2021 - 19:52:02 +0000)
DRAM: 2048 MiB
Trying to boot from MMC2

That five power up attempt as you can see.
I tried to rollback uboot to 2020.04, but it behave in exactly same way.`
All three boards was ordered at the same time, in one package.
Is anyone can reproduce this?
Is there anything else to try, or I should just give up and stick with microSD for now? (Although I probably could left uboot and /boot on microSD and then put rootfs on eMMC, but that another story.)
