I then copied the MLO and U-BOOT.IMG files to the /boot/msdos partition of my BBB (as directed by the port README) and performed a reboot. Alas, the system would not boot up. It appears it cannot locate a DTB file: >>>> >>>> =====8<===== >>>> [[...]] >>>> Rebooting... >>>> >>>> U-Boot SPL 2017.07 (Jul 26 2017 - 22:56:32) >>>> Trying to boot from MMC1 >>>> *** Warning - bad CRC, using default environment >>>> >>>> reading u-boot.img >>>> reading u-boot.img >>>> >>>> >>>> U-Boot 2017.07 (Jul 26 2017 - 22:56:32 +0000) >>>> >>>> CPU : AM335X-GP rev 2.0 >>>> I2C: ready >>>> DRAM: 512 MiB >>>> No match for driver 'omap_hsmmc' >>>> No match for driver 'omap_hsmmc' >>>> Some drivers were not found >>>> MMC: OMAP SD/MMC: 0, OMAP SD/MMC: 1 >>>> *** Warning - bad CRC, using default environment >>>> >>>> <ethaddr> not set.

I forgot to mention in my original post that I am running 11-STABLE on my BeagleBoneBlack. There, /usr/src/sys/modules/dtb/am335x/Makefile still references the old names whereas HEAD references the new ones (creating links for the old ones): >> >> =====8<===== >> root@chumby:/build/src # cat head/sys/modules/dtb/am335x/Makefile >> # $FreeBSD: head/sys/modules/dtb/am335x/Makefile 312969 2017-01-29 22:06:52Z gonzo $ >> # All the dts files for am335x systems we support. >> DTS= \ >> am335x-bone.dts \ >> am335x-boneblack.dts \ >> am335x-bonegreen.dts \ >> ufw.dts >> >> LINKS= \ >> ${DTBDIR}/am335x-bone.dtb ${DTBDIR}/beaglebone.dtb \ >> ${DTBDIR}/am335x-boneblack.dtb ${DTBDIR}/beaglebone-black.dtb >> >> .include <bsd.dtb.mk> >> root@chumby:/build/src # cat releng_11/sys/modules/dtb/am335x/Makefile >> # $FreeBSD: stable/11/sys/modules/dtb/am335x/Makefile 312756 2017-01-25 14:49:42Z loos $ >> # All the dts files for am335x systems we support. >> DTS= \ >> beaglebone.dts \ >> beaglebone-black.dts \ >> ufw.dts >> >> .include <bsd.dtb.mk> >> root@chumby:/build/src # >> =====>8===== >> >> Am I correct in thinking that creating symlinks in /boot/dtb for am335x-bone.dts and am335x-boneblack.dts to their respective old names should fix my booting problem, then? > > Yes. Thank you. I put the .dtb symlinks in place and that fixed the problem. My BBB now boots properly using the new U-Boot. Cheers, Paul.help
