The rk3288 spl size is very close to 32KB while the rk3288 bootrom

patch, the SPL size will exceed 32KB if we do not enable macro
CONFIG_ROCKCHIP_SPL_BACK_TO_BROM.
With CONFIG_ROCKCHIP_SPL_BACK_TO_BROM=y, it fails to boot with no output
on the console.
This patch has test with 2GB DDR3 and 2GB/4GB LPDDR3.
Thanks for the patch!
Unfortunately, fails to build the firefly-rk3288 target, using
arm-linux-gnueabihf-gcc (Debian 6.1.1-9) 6.1.1 20160705, applied to
u-boot master 01c5075506afcb7a74e0db8600af8979f45881b5:
CC spl/arch/arm/mach-rockchip/rk3288/sdram_rk3288.o

did you mean 'rockchip_noc'?
plat->num_channels = of_plat->rockchip_num_channels;
- plat->num_channels = of_plat->rockchip_num_channels;
+ plat->num_channels = 2;
firefly-rk3288 deploy CONFIG_OF_PLATDATA, driver read platform data
from include/generated/dt-structs.h which is generated according to dts
file.
Please try above change.
With this change, it builds, but it hangs at boot:
U-Boot SPL 2016.09-rc2+dfsg1-2~20160910~6 (Sep 10 2016 - 18:51:28)
Trying to boot from MMC1
U-Boot 2016.09-rc2+dfsg1-2~20160910~6 (Sep 10 2016 - 18:51:28 +0000)
Model: Firefly-RK3288
DRAM:
Could you help to add DEBUG macro in common.h like:
#indef CONFIG_SPL_BUILD
#define DEBUG
#endif
So that we can figure out where it is.
This is on a firefly with 2GB of ram. I also have one with 4GB of ram,
hence my interest in this patch series!
live well,
vagrant
