Bug ID: 291182
Summary: usb drd/otg not working anymore on allwinner h3
Product: Base System
Version: CURRENT
Hardware: arm
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
i don't know what has happened
for long time drd doesn't work anymore
device is actually nanopi neo core board which has allwinner h3 soc, 512m ram
and 8g emmc. for some mysterious reason, board has no fdt defs, uboot board
config, nothing
so i made my own
emmc works, altho if i use ethernet too, it doesn't always work. if use just
microsd, eth has almost no issues at all. ethernet issues manifest in broken
frames going out, at least switch reports tens of thousand of errors on port,
dhcp goes through sometimes. down/up cycle gets it working
but main issue, usb_template worked perfectly until it didn't. either uboot or
kernel issue. with recent uboot, i tried 13 too, no luck. older uboots are hard
to build. to verify it works then
so any ideas how to debug, check or fix it
i tried to bisect the commits but none of them worked. i can't remember if i
upgrade uboot at same time
