Hi Alexander,

    The tinker board already enable TPL, so it should be use TPL instead of SPL with mkimage tool.

The idbloader should have including both, if the idbloader boot fail, could you share the boot log?


Thanks,
- Kever

Anyone know a way to get a functional u-boot on the rk3288? (Tinkerboard, SD)

The docs seem to recommend:
$ /tmp/arm-build/tools/mkimage -n rk3288 -T rksd -d 
arm/tinkerboard/u-boot-spl-dtb.bin out

However, that produces:
Warning: SPL image is too large (size 0xb000) and will not boot

I saw this patch to disable I2C in the SPL to reduce its size:
https://github.com/xypron/u-boot-patches/blob/df2ceb65fb4cc433aa17304ed9d3d591c14ef5ac/0001-configs-
inker-rk3288-disable-CONFIG_SPL_I2C_SUPPORT.patch

However, that breaks the build :-|

LD spl/u-boot-spl
arm-unknown-haiku-ld.bfd: drivers/built-in.o: in function `rk8xx_write':
/tmp/arm-build/drivers/power/pmic/rk8xx.c:30: undefined reference to 
`dm_i2c_write'
arm-unknown-haiku-ld.bfd: drivers/built-in.o: in function `rk8xx_read':
/tmp/arm-build/drivers/power/pmic/rk8xx.c:43: undefined reference to

make: *** [Makefile:1762: spl/u-boot-spl] Error 2
make: Leaving directory '/tmp/arm-build'
Disabling SPL Power then results in an error compiling MMC support
Any alternative methods to getting u-boot running from SD?
Rockchip devices seem to be kind of complex to get going :-|
