Indeed we cannot boot from USB with the current re@ generated image. As said before in this thread u-boot needs the raspberrypi,firmware-reset node to be present to reset the usb controller. This also means that we cannot boot from sd and use USB drives from u-boot currently. If, like Andy did, we use only the dtb from rpi-firmware git master everything works. One issue was genet related but was fixed by cb00fc7c4d. The problem is that if we use start* or fixup* (not sure since those files have to be synced) from rpi-firmware git master (tested with commit d06d94e) there is no dtb available for u-boot : U-Boot> fdt addr fdt_addr libfdt fdt_check_header(): FDT_ERR_BADMAGIC U-Boot> fdt addr fdt_addr_r libfdt fdt_check_header(): FDT_ERR_BADMAGIC I really don't want to dig into this rabbit hole now so I'll test again when rpi-firmware have another release. In the mean time if you want to usb-boot your rpi4 just download the dtb from the d06d94e commit and that will work now. -- Emmanuel Vadot <manu@bidouilliste.com> <manu@freebsd.org>
