H A D | qrb2210-rb1.dts | e1877196 Wed Apr 05 10:50:34 CDT 2023 Konrad Dybcio <konrad.dybcio@linaro.org> arm64: dts: qcom: Add initial QTI RB1 device tree
Add an initial device tree for the QTI RB1 development board, based on the QRB2210 (QCM2290 derivative) SoC. This device tree targets the SoM revision 4, a.k.a. the Mass Production SKU.
To get a successful boot, run:
cat arch/arm64/boot/Image.gz arch/arm64/boot/dts/qcom/qrb2210-rb1.dtb >\ .Image.gz-dtb
mkbootimg \ --kernel .Image.gz-dtb \ --ramdisk some_initrd \ --output rb1-boot.img \ --pagesize 4096 \ --base 0x8000 \ --cmdline 'some cmdline'
fastboot boot rb1-boot.img
There's no dtbo or other craziness to worry about. For the best dev experience, you can erase boot and use fastboot boot everytime, so that the bootloader doesn't mess with you.
If you have a SoM revision 3 or older (there should be a sticker on it with text like -r00, where r is the revision), you will need to apply this additional diff:
aliases { - serial0 = &uart0; + serial0 = &uart4;
/* UART connected to the Micro-USB port via a FTDI chip */ - &uart0 { + &uart4 {
That should however only concern preproduction boards.
