PROCESSOR-SDK-AM64X: eMMC raw boot using uSD pieces

Part Number: PROCESSOR-SDK-AM64X


Tool/software:

Hi -

I am following the steps shown here

3.1.1.5. SD, eMMC and USB — Processor SDK AM64X Documentation

to try to boot a AM642 EVM from eMMC instead of the supplied SD card with "raw" rather than FAT layout (because raw is needed for HS boot eventually).  There seems to have been more than one set of block offsets needed to write the data from the SD to the eMMC, but following the ones in the document and using the SD card files that work in FAT mode, I can't get any serial output when trying to boot from eMMC.

This is using the boot0 eMMC "partition" (tried both from U-Boot and Linux with dd)

BOOTCONF switches are set to 

               SW3          SW2

(bit 15) 00000010 11000011 (bit0)

... any suggestions?

Thanks
