Tool/software:
My main question is: why "rpmsg_client_sample.ko" and "rpmsg_char_simple" can't run normally as described in Foundational_Components_IPC_J721E
(1) The board is booted with SD card with prebuilt images.
Linux kernel version '6.6.44-ti-01478-g541c20281af7-dirty SMP"
(2) /opt/vision_apps/vx_app_arm_ipc.out can run normally
...... 136.207200 s: IPC: RX: mcu2_0 -> mpu1_0 (port 13) msg = 0xdead000e 136.207208 s: IPC: RX: mcu2_1 -> mpu1_0 (port 13) msg = 0xdead000e 136.207216 s: IPC: RX: c6x_1 -> mpu1_0 (port 13) msg = 0xdead000e 136.207224 s: IPC: RX: c6x_2 -> mpu1_0 (port 13) msg = 0xdead000e 136.207232 s: IPC: RX: c7x_1 -> mpu1_0 (port 13) msg = 0xdead000e
(3)Only two files are compiled on Host and copied onto the J721e_evm board:
rpmsg_client_sample.ko, rpmsg_char_simple. They are built according to Foundational_Components_IPC_J721E.
(4)Backup /lib/firmware/j7* soft links and create new soft links as follows:
