I started out with uboot_beaglebone_eabi_port, but although I was able to get it to build (after removing the 0 length patch files), I couldn't seem to get crotchet-freebsd to pick it up. It seems that the `uboot_eabi_port` tools is missing; I'm using pkgng, so maybe that's the problem. I noticed that uboot_beaglebone_eabi_port with the 1Ghz patches builds against u-boot-2014.01 so I downloaded u-boot-2014.01.tar.bz2, unpacked it in the crotchet-freebsd directory and replaced the patches in crotchet-freebsd/boards/BeagleBone/files with the 1Ghz ones and tried a crotchet build. This failed to link with: armv6-freebsd-ld: region .sram is full (u-boot-spl section .data) armv6-freebsd-ld: region .sram is full (u-boot-spl section .data) armv6-freebsd-ld: section .u_boot_list [00000000402f0400 -> 00000000402f0477] overlaps section .text [00000000402f0400 -> 000000004030657b] armv6-freebsd-ld: u-boot-spl: section .text lma 0x402f0400 overlaps previous sections armv6-freebsd-ld: u-boot-spl: section .rodata lma 0x4030657c overlaps previous sections armv6-freebsd-ld: u-boot-spl: section .data lma 0x4030aec8 overlaps previous sections So no luck there. I did try also building Patrick Kelsey's fork of u-boot which failed with very similar errors: armv6-freebsd-ld: region .sram is full (u-boot-spl section .rodata) armv6-freebsd-ld: region .sram is full (u-boot-spl section .rodata) armv6-freebsd-ld: section .data [00000000402f0400 -> 00000000402f1141] overlaps section .text [00000000402f0400 -> 0000000040307257] armv6-freebsd-ld: u-boot-spl: section .text lma 0x402f0400 overlaps previous sections armv6-freebsd-ld: u-boot-spl: section .u_boot_list lma 0x402f1144 overlaps previous sections I did notice that the *original* patches for uboot_beaglebone_eabi_port seem to remove api_net.c from the build, perhaps this was an effort to slim down the binary to avoid this issue (however, the 1Ghz patches nuke the patches that removed api_net.c and it's callers). Finally, I took a look at the patches to see if I could rework them for u-boot-2014.04 (since it was recently released), but it seems that there have been significant changes since 2013.04 so I need to learn more about u-boot before going near that! Thanks, -W.
