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 >> arch/arm/mach-rockchip/rk3288/sdram_rk3288.c: In function >> 'conv_of_platdata': >> arch/arm/mach-rockchip/rk3288/sdram_rk3288.c:1042:30: error: 'struct >> dtd_rockchip_rk3288_dmc' has no member named 'rockchip_num_channels'; >> 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: 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
