eMMC boot mode for TE0820

Hi,

I'm working with a TE0820 / TE0703 setup, trying to enable boot from the on-board eMMC device.

As I understand it, this would require a new CPLD image in order to configure the boot mode pins on the SoC.

I've had a look at the options in
https://shop.trenz-electronic.de/en/Download/?path=Trenz_Electronic/Modules_and_Module_Carriers/4x5/TE0820/REV03/Firmware
but those seem to only support combinations of SD, QSPI, and JTAG.

Would you be able to provide an image that implements boot from SD/eMMC, selectable by the S2 switch on the TE0703?

My exact board revisions are
TE0820-03-3BE21FA
TE0703-06

Hi,
with current firmware you can use emmc for secondary boot.
-->put boot.bin on QSPI flash and use uboot for emmc access.

But in case you like to try out primary boot from emmc, please send a email to support@trenz-electronic.de
