The current images of fel-mass-storage failed to boot on a H2+ OTT box (Sunvell R69)

It stucks after:

Looking at the u-boot config used I used pretty optimistic values:

CONFIG_DRAM_CLK=624
CONFIG_SYS_CLK_FREQ=1008000000

I would try to downclock both CPU and DRAM - AFAIK this box has no CPU voltage switching and I wouldn't trust in DRAM quality in cheap TV boxes :smile:

For the reference Armbian u-boot config for this device has

CONFIG_DRAM_CLK=576
CONFIG_SYS_CLK_FREQ=480000000
