2.42.0

The Snapdragon 720G (sm7125) is software-wise very similar to the Snapdragon 7c with minor differences in clock speeds and as added here, it uses the Kryo 465 instead of Kryo 468.

2.42.0

There are 6 Xiaomi smartphones with the SM7125 SoC:

- POCO M2 Pro (gram)
- Redmi Note 9S (curtana)
- Redmi Note 9 Pro (Global, joyeuse)
- Redmi Note 9 Pro (India, curtana)
- Redmi Note 9 Pro Max (excalibur)
- Redmi Note 10 Lite (curtana)

These devices share a common board design (a.k.a miatoll) with only a few differences. Add support for the common board, as well as support for the global Redmi Note 9 Pro.

2.42.0

Would your device boot if you:

- removed qcom,board-id and qcom,msm-id
- created the image like this:

mkbootimg \
--kernel arch/arm64/boot/Image.gz \
--dtb arch/arm64/boot/dts/qcom/blahblah.dtb \
--ramdisk blah.img \
--pagesize 4096 \
--base 0x0 \
--kernel_offset 0x8000 \
--ramdisk_offset 0x1000000 \
--tags_offset 0x100 \
--cmdline "foobarbaz" \
--dtb_offset 0x1f00000 \
--header_version 2 \
-o boot.img

?

Konrad

Seems like my device needs those properties, it does not boot without msm-id and board-id and the command you sent.

Sincerely,
David

Applied, thanks!
