USB gadget simply doesn't work right now on PX30. Tested on PX30 EVB and
PX30 Ringneck with Linux mainline and Rockchip 5.10 Linux as well as
U-Boot.
Do you mean for both U-Boot and kernel, including mainline version and
rockchip version,
and on both PX30 EVB and Ringneck board, all SW&HW have no USB gadget
working?
Mainline U-Boot on PX30 Ringneck -> not working
PX30 EVB and PX30 Ringneck in Rockchip 5.10 kernel when I tested about
two years or so ago -> working-ish, but very unstable on Ringneck and I
think not working at all on PX30 EVB
PX30 Ringneck (possibly PX30 EVB, I don't remember) in upstream 6.0.2
(and also next-20221216) -> not working
I don't know what you mean by SW&HW, how am I supposed to differentiate
the two?
FYI, I tried to add **some** support in upstream, it got merged and then
reverted because it broke STM platforms, c.f.
https://lore.kernel.org/linux-usb/20221206-dwc2-gadget-dual-role-v2-0-0de821615...@theobroma-systems.com/
and
https://lore.kernel.org/linux-usb/[email protected]/
I can test stuff again and provide a bit more info if requested.
So when you test this, does the maskrom mode works? because it sounds
like maybe
the HOST PC is the one have issue at the moment.
I can use rkdeveloptool just fine when using Rockchip blobs from rkbin,
no issue with the HW asf ar as I know.
Cheers,
Quentin
