Here I'm talking about u-boot itself, not FreeBSD, not booting from USB on the RPI4, U-Boot, only U-Boot. Right now, using the latest taggued release of rpi-firmware (20201201), there is no raspberrypi,firmware-reset compatible node in the dtb so U-Boot cannot init the usb controller. That doesn't mean that the RPI cannot boot from usb, it can and will load u-boot, but when u-boot will look for it's "root device" (the usb drive) this will fail as the usb controller couldn't be init. This also means that when we boot from SD card, we cannot access usb drives from U-Boot, as, again, the usb controller wasn't init. -- Emmanuel Vadot <[email protected]> _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-arm To unsubscribe, send any mail to "[email protected]"
