Hi,

First of all I am new to IMX processors and also Android source.

I am trying to implement cortex m4 for remote control interfacing.

Evk kit provided by MYIR.

Android version - 9

kernel version - 4.14

trying to activate rpmsg in the using "modprobe imx_rpmsg_tty" command but it shows error as below

evk_8mm:/data/local/tmp # modprobe imx_rpmsg_tty
modprobe: /etc/modprobe.conf: No such file or directory
modprobe: /etc/modprobe.d: No such file or directory
modprobe: chdir '/lib/modules/4.14.98'

Kindly support urgently.

thanks in advance.

Okay thanks for support again,

I was able to write the code for gpio interrupt.

but the interrupt occurs if i run the m4 at uboot before starting the kernel, and does not work when the the kernel is loaded.

is there any way that i can dissable the interrupt clearing on kernel side?

Hello,

You need to upgrade your android to android 10 or android 12 since rpmsg doesn't work on Android 9 and kernel 4.14.
