Cubieboard2 with custom bootloader

[Mihai Carabas]

Hello Manu,

We've tried multiple methods:
1. precompiled u-boot from FreeBSD packages  + ubldr
2. u-boot compiled from sources + your patches + ubldr
3. precompiled u-boot from FreeBSD packages + kernel
4. u-boot compiled from sources + your patches + kernel

For 1 and 2 we didn't manage to start ubldr. Do we need to add any custom
option to u-boot?

For 3, we manage to boot it normally.

With 4, we have the following error:
=> setenv bootcmd "fatload mmc 0:1 0x42000000 kernel.bin; go 0x42000000"
=> boot
reading kernel.bin
6758372 bytes read in 589 ms (10.9 MiB/s)
## Starting application at 0x42000000 ...
panic: mtx_lock() of spin mutex (null) @
/root/bhyve-ARM/src/sys/arm/arm/pmap-v6.c:6350
cpuid = 0
Uptime: 1s

How did we compile u-boot:
- we took 2016.11 from here[1] (u-boot-2016.11.tar.bz2)

- apply patches and compile
root at bsd:~/u-boot-2016.11 # patch -p1 -i ../
people.freebsd.org/\~manu/uboot/0001-....
root at bsd:~/u-boot-2016.11 # make CROSS_COMPILE=arm-none-eabi-
Cubieboard2_config
root at bsd:~/u-boot-2016.11 # make CROSS_COMPILE=arm-none-eabi-

- and used the u-boot-sunxi-with-spl.bin
​
Do you have any insight? (at least for thr 4th method)

Thank you,
Mihai
