Hi,
hopefully my english and my linux skills are good enough (little bit experience with raspi and odroid
i´ve setup Rock Pi 4 C with nvme boot from spi (first mmc)
Armbian 21.02.3 Buster with Linux 5.10.21-rockchip64
after some difficulties to setup boot from nvme it is running on ADATA SX6000PNP
when i perform reboot - mostly no reboot
after disconnect power and reconnect no boot until i wait > 1 minute
during the day i try sudo armbianmonitor - u and i get a link now when i use this command there is no more link
serial console - i get no output but i can log in after a while
Thanks
