Hi All,
I'm trying to boot a CHIPPro with the stock 4.12 rc1 kernel. If I make no modifications to the sun5i-gr8-chip-pro.dtb the kernel boots but can't find the root partition.
So I added the partitions to the dts file
diff --git a/arch/arm/boot/dts/sun5i-gr8-chip-pro.dts b/arch/arm/boot/dts/sun5i-gr8-chip-pro.dts index c55b11a..0e61e6b 100644 --- a/arch/arm/boot/dts/sun5i-gr8-chip-pro.dts +++ b/arch/arm/boot/dts/sun5i-gr8-chip-pro.dts @@ -146,6 +146,32 @@ reg = <0>; allwinner,rb = <0>; nand-ecc-mode = "hw"; + nand-on-flash-bbt; + + spl@0 { + label = "SPL"; + reg = /bits/ 64 <0x0 0x400000>; + }; + + spl-backup@400000 { + label = "SPL.backup"; + reg = /bits/ 64 <0x400000 0x400000>; + }; + + u-boot@800000 { + label = "U-Boot"; + reg = /bits/ 64 <0x800000 0x400000>; + }; + + env@c00000 { + label = "env"; + reg = /bits/ 64 <0xc00000 0x400000>; + }; + + rootfs@1000000 { + label = "rootfs"; + reg = /bits/ 64 <0x1000000 0x1f000000>; + }; }; };
and now the kernel finds the partition but it times out trying to mount it. It seems to be something in the dts files because if I use the ntc-gr8-crumb.dts from the ntc 4.4.30 kernel then the system boots all the way to userland.
