Again, the Switch = did not allow me to do *any* I/O other than the serial console and SD card.= Heck, my UART "adapter" (wires soldered to spare joycon rail) is so janky = that the characters were sometimes corrupted :D > From my first overview the strejda - port isn=E2=80=99t merged in src-hea= d? Yeah, from what I remember mmel@ saying, this is mostly because the boot pr= ocess on the Jetson was a hack and he didn't want to commit support for a d= evice that can't boot normally. But in theory it should be possible to build alternative firmware.. On the = Switch, you inject coreboot with an edk2/u-boot/whatever payload via the US= B bug. On the Jetson, you could probably flash coreboot on the usual flash = chip and it would boot normally maybe I guess??.. > Should we use these informations in Wiki respectively are > you(&Mikael) interested in this? I'm not really interested in nvidia hardware, no. > I don`t have a Jetson available but thinking of it=E2=80=A6 My advice would be don't support that green company.
