jFYI/FWIW, reverting [1-2] allows getting rid of below warnings on R-Car3, when running basic fastboot commands (e.g. fastboot getvar):
[ 8.035764] status: -104 ep 'ep1' trans: 0 [ 18.744354] status: -104 ep 'ep1' trans: 28 [ 18.748950] status: -104 ep 'ep1' trans: 9 [ 18.753370] status: -104 ep 'ep1' trans: 28 [ 26.064761] status: -104 ep 'ep1' trans: 28
I don't think reverting this patch in mainline U-Boot would be a good idea, as it is required to get fastboot to work at all on sunxi platforms with the MUSB controller.
Did you investigate the issue to see what is happening here precisely?
I attempted to record some traces to visualize the functions called during my use-case, but it seems like lib/trace.c and cmd/trace.c are not usable on arm64 (no U-Boot console output on my H3-ULCB-KF). Anyone with a hint in this direction?
Anyway, given that I use an out-of-tree USB gadget driver, any logs I can share will only be of limited/little help, I assume. I expect the discussion to make more sense during upstreaming of USBHS R-Car Linux driver. Now, it is more of a heads up.
Best regards, Eugeniu.
