ls1046 unable to boot from eMMC

gavingao

Our PCB unable to boot from eMMC, while SD card boot is fine.

After burn the image to eMMC by flex-installer, and set boot selection to eMMC boot, the board seems trigger reset continuously.

Is there expert here can review the RCW and give some advice.

Here is the RCW for eMMC.

We finally identified the problem. The RCW in composite firmware image of eMMC was empty somehow. after fixed this trouble. We can boot from eMMC now.

Here is the schematic of eMMC and SD card part.

Dear @gavingao,

Did you remove the SD card when you try to boot from the emmc?
Did you add the node for the eMMC into the Device Tree?

Surely we removed the sd card.

I think the problem should be also irrelevant to the dts, because the boot didn’t pass the BL1 at all.

Is there any diagram describe the boot rom code logic?
