Direct flash eMMC from linux host with aml-flash tool

I’d like to avoid to first flash and boot my CM4 from an SD card and then pass this to the eMMC after logging into the CM4.

Any linux images available to directly flash into emmc with the aml-flash-tool ?

When testing it I get: “ERROR: Try to burn to eMMC storage, but the image installation type is ‘SD-USB’, please use ‘EMMC’ image!”

But maybe I’m missing something ? I have my own simple base board with just a UART and USB ports to flash. The device is detected properly
