As the other thread is getting a bit cluttered I thought I'd start a new one. Thanks to the good work of @pask and others we now have a working image for the M4 v2. However, despite following instructions to the letter. I can't get the board to boot from the eMMC card, in fact I don't think the board even recognizes the card ( I've tried different ones ) Also not being able to connect via a serial cable is hampering my attempts at debugging the boot process. Cany anyone put up a Muppets guide on the steps required to achieve this ?
