Hello
I want to enable the character device RPMSG. I'm using Yocto as a build system. I added kernel configuration fragment:
CONFIG_RPMSG_VIRTIO=y CONFIG_RPMSG_PROTO=y CONFIG_RPMSG_CHAR=y CONFIG_TI_PRUSS=y CONFIG_PRU_REMOTEPROC=y CONFIG_RPMSG_PRU=y CONFIG_SAMPLE_RPMSG_CLIENT=y CONFIG_RPMSG_KDRV_DEMO=y
But still, no /dev/char/rpmsg_ctrl device is available.
I found that only the rpm_char_init() function from drivers/rpmsg/rpmsg_char.c is called when system boot up.
The probe () function will not be called.
Why is it not working?
Thank you form help.
