That is rather odd. There are no meaningful changes to the upstream code in this version of the package. Where did you get uart0-helloworld-sdboot.sunxi from, since it was not shipped in version 1.4.2+git20181114.6d598a-3, did you use the same binary in both tests? Possibly your freshly built version ended up using a different libusb, since that is what usb_bulk_send is reporting an error from. Are you in a position to test 1.4.2+git20221128.530adf-2 from Bookworm? It is a much newer upstream snapshot so may have resolved your issue. Thanks, Ian.
