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/df2ceb65fb4cc433aa17304ed9d3d5...
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 `dm_i2c_read' make[1]: *** [scripts/Makefile.spl:404: spl/u-boot-spl] Error 1 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 :-| -- Alex
