Hi,
I have found that my Mango Pi is very jittery, also when I reboot it there
is probably garble on the UART link causing it to fall into u-boot prompt.
I have tried:
env set bootdelay 0
env set bootdelay -1
saveenv
and reset
but it doesn't seem to work. Any garble will still cause a break to u-boot
console. There is a firmware image on the flash and in DTB under config
but how do I access that from OpenBSD? Is there any drivers I can look at
for making this work? I believe it goes on the "binman" device that is not
configured.
deneb# dmesg|grep binman
"binman" at mainbus0 not configured
Granted that there isn't an easy answer, I'll look at this perhaps in autumn.
Here is my dmesg:
