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. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
