Hi All,

I found this wiki said SoC seems not boot via eMMC boot partition.

I have a Banana Pi M2+ with 8 GB eMMC. I try to write U-Boot (with SPL) to eMMC boot partition, i.e. mmcblk2boot0 or mmcblk2boot1, and cannot get it to work neither.

Can H3 boot from boot0 or boot1 partition of eMMC? If yes, how to achieve that?

Best regards,

Wei-Hung Yang

I'm using following fastboot-based flashing method on A20:

Thank you, plaes.

But it looks like fastboot method only manipulates user data area of eMMC. It flashes images to loader1, loader2, esp and system partition which are all logical partition, not hardware partition of eMMC.

I have no experience with H3 itself, but A64 boots from these partitions in agreement with the eMMC 5.1 (JESD84) specs.

Unlike booting from the user partition (the usual case), here BROM expects BOOT0/SPL to be located right at the first sector.
