Thanks for your answer

I was thinking of a similar approach as it was used over here https://www.exploitee.rs/index.php/Amazon_FireTV where they had a comparable problem to interface a emmc chip.
since the board will most likely die during this operation I would prefer to upload a correct first stage bootloader (the initial u-boot) via MFGtool into ram.

can you give me a hint where I could find one of those - or should the ones includes in the MFGTool from this forum be working?

I found a K4 and a Touch Teardown with shields removed.... i keep looking

Thanks
