Hello,
I've just started using the SDK 9.0 and I'm running into multiple issues trying to add and build additional image sensor module drivers for the OV5647 and AR0521 using the make commands. It looks like the online documentation hasn't changed from the 8.6 SDK version and I've been successfully adding and building image sensors overlays and drivers using the 8.6 SDK version . I've been following the instructions here:
So far I've diverted from them in the following ways to try and get modules and additional overlays to build:
Add build tool chain to the $PATH:
export PATH=~/ti/AM62A/SDK-9_0/external-toolchain-dir/arm-gnu-toolchain-11.3.rel1-x86_64-aarch64-none-linux-gnu/bin:$PATH
Add overlay dtbs to the base Linux build directory Rules.make file:
.... KERNEL_DEVICETREE?= ti/k3-am62a7-sk.dtb ti/k3-am62a7-sk-csi2-imx219.dtbo ti/k3-am62a7-sk-fusion.dtbo ti/k3-am62a7-sk-ethernet-dc01.dtbo ti/k3-am62a7-sk-csi2-ov5647.dtbo ti/k3-am62a7-sk-csi2-ar0521.dtbo ....
Created dtso overlays and updated the Makefile in the ".../arch/arm64/boot/dts/ti/" Linux build directory to mimic the imx219 image sensor:
k3-am62a7-sk-csi2-ar0521-dtbs := k3-am62a7-sk.dtb k3-am62a7-sk-csi2-ar0521.dtbo k3-am62a7-sk-csi2-ov5647-dtbs := k3-am62a7-sk.dtb k3-am62a7-sk-csi2-ov5647.dtbo dtb-$(CONFIG_ARCH_K3) += k3-am62a7-sk-csi2-ar0521.dtb dtb-$(CONFIG_ARCH_K3) += k3-am62a7-sk-csi2-ov5647.dtb
I'm able to build the device tree overlays successfully using the command "make ARCH=arm64 CROSS_COMPILE=aarch64-none-linux-gnu- dtbs"
The "make ARCH=arm64 CROSS_COMPILE=aarch64-none-linux-gnu- Image" command doesn't produce any errors but it is only showing a few build messages unlike the plethora it did with 8.6 version so I'm suspicious that it is working.
The "make ARCH=arm64 CROSS_COMPILE=aarch64-none-linux-gnu- modules" command produced prompted a lot of questions on inital run that I tried to answer as best as I could and then errored out in a way that I'm not sure how to fix:

I'm wondering if this is reproducible or I'm missing some kind of configuration still some where?
Thank you for your support,
