The generated bootable u-boot-rockchip-spi.bin can be written to 0x0 of SPI NOR flash. The FIT image is loaded from 0x60000, same as on RK35xx boards. => sf probe SF: Detected zb25vq128 with page size 256 Bytes, erase size 4 KiB, total 16 MiB => load mmc 1:1 10000000 u-boot-rockchip-spi.bin 1376768 bytes read in 66 ms (19.9 MiB/s) => sf update ${fileaddr} 0 ${filesize} device 0 offset 0x0, size 0x150200 1126912 bytes written, 249856 bytes skipped in 14.22s, speed 100542 B/s Signed-off-by: Jonas Karlman Reviewed-by: Tianling Shen Reviewed-by: Kever Yang --- arch/arm/dts/rk3328-orangepi-r1-plus-lts-u-boot.dtsi | 16 ++++++++++++++++ arch/arm/dts/rk3328-orangepi-r1-plus-u-boot.dtsi | 16 ++++++++++++++++ 2 files changed, 32 insertions(+) (limited to 'arch') diff --git a/arch/arm/dts/rk3328-orangepi-r1-plus-lts-u-boot.dtsi b/arch/arm/dts/rk3328-orangepi-r1-plus-lts-u-boot.dtsi index 7cdf6913795..0dbe5a01f98 100644 --- a/arch/arm/dts/rk3328-orangepi-r1-plus-lts-u-boot.dtsi +++ b/arch/arm/dts/rk3328-orangepi-r1-plus-lts-u-boot.dtsi @@ -17,6 +17,22 @@ }; }; +&spi0m2_clk { + bootph-pre-ram; +}; + +&spi0m2_cs0 { + bootph-pre-ram; +}; + +&spi0m2_rx { + bootph-pre-ram; +}; + +&spi0m2_tx { + bootph-pre-ram; +}; + &vcc_sd { bootph-pre-ram; }; diff --git a/arch/arm/dts/rk3328-orangepi-r1-plus-u-boot.dtsi b/arch/arm/dts/rk3328-orangepi-r1-plus-u-boot.dtsi index 35baeb2464b..1af75ada1a6 100644 --- a/arch/arm/dts/rk3328-orangepi-r1-plus-u-boot.dtsi +++ b/arch/arm/dts/rk3328-orangepi-r1-plus-u-boot.dtsi @@ -17,6 +17,22 @@ }; }; +&spi0m2_clk { + bootph-pre-ram; +}; + +&spi0m2_cs0 { + bootph-pre-ram; +}; + +&spi0m2_rx { + bootph-pre-ram; +}; + +&spi0m2_tx { + bootph-pre-ram; +}; + &vcc_sd { bootph-pre-ram; }; -- cgit v1.3.1
