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.
