Talking about uuu, has anybody managed to get that going on the i.MX 8M Mini yet? Regular USB device/host functionality works great but last I tried gadget functionality in SPL it gave me quite some grief.
Please see this series: https://patchwork.ozlabs.org/project/uboot/list/?series=251796&state=*
I haven't had a chance to rework it. Feel free to work to submit it if you have a chance.
Tommaso has recently tested it: https://www.mail-archive.com/search?l=u-boot@lists.denx.de&q=subject:%22...
Hi Fabio, I share here a more recent version of your series:
https://patchwork.amarulasolutions.com/project/linux-amarula/list/?series=37...
This series brings USB gadget support for i.MX8MM and allows the usage of the Serial Download Protocol, which is a convenient way for loading U-Boot via the 'uuu' tool and and flashing the eMMC via the U-Boot 'ums' command.
Tested on board based on iMX8MM SOC:
