Activating of cortex m4 in android 9 based imx8mm

[hashir]

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?

Thanks , but i got it worked on Android 9 and kernel 4.14.

Can you give me example for GPIO interrupt.

It will be very helpful.

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.
