Other Parts Discussed in Thread: AM1808
I am using the PRU of AM1808,I have builded the suart_emu.ko.
NOW ,I found a qustion :
when the system start, the soft uart run ok,can receive and send data ;
but when the system run a time, the soft uart may can not receive and send data;
so,I take steps:
modprobe -r suart_emu
insmod suart_emu.ko
Then ,I used the uart ,it run ok
I do not know why?
