Tool/software:
Dear Supporters,
I'm trying to configure the sk-am62a-lp to work as a USB HID device. In order to accomplish this, I've followed the instructions in 3.2.1. Users Guide — Processor SDK AM62Ax Documentation
Using WSL I installed the SDK 9.2. While in ti-processor-sdk-linux-edgeai-am62axx-evm-09_02_00_05/board-support/ti-linux-kernel-6.1.80+gitAUTOINC+2e423244f8-ti/ I did the exports mentioned in the guide. Then, after customizing the configuration with
make ARCH=arm64 CROSS_COMPILE="$CROSS_COMPILE_64" menuconfig
I ran the following commands:
make ARCH=arm64 CROSS_COMPILE="$CROSS_COMPILE_64" distclean
make ARCH=arm64 CROSS_COMPILE="$CROSS_COMPILE_64" Image
make DTC_FLAGS=-@ ARCH=arm64 CROSS_COMPILE="$CROSS_COMPILE_64" ti/k3-am62a7-sk.dtb
make ARCH=arm64 CROSS_COMPILE="$CROSS_COMPILE_64" modules
I installed the modules in a separate folder with
make ARCH=arm64 CROSS_COMPILE="$CROSS_COMPILE_64" INSTALL_MOD_PATH=./modules_install modules_install
This command installed the modules in the directory /modules_install/lib/modules/6.1.80-dirty
The device tree was copied to the SK-AM62A-LP with the command:
scp arch/arm64/boot/dts/ti/k3-am62a7-sk.dtb root@<device_ip>:/boot/dtb/ti
If I copy the modules with:
scp -r ./modules_install/lib/modules/6.1.80-dirty/ root@<device_ip>:/lib/modules/
When I run the command "modprobe imx219" I get the output
modprobe: ERROR: could not insert 'imx219': Exec format error
If I copy the generated kernel with:
scp arch/arm64/boot/Image root@<device_ip>:/boot/
The board no longer boots correctly. The log in the serial connection is:
