I am trying to implement the "Waking up the Host CPU Using the MCU" example here Using the MCU SDK and API: Code examples | Intel® Software
I've managed to download the script onto the board, but when I enter the commands "cat /proc/interrupts | grep intel_psh_ipc" And "cat ttymcu0", I get "47: 27 0 IO-APIC-fasteoi intel_psh_ip" AND "cat: ttymcu0: No such file or directory", which looks like the script isnt running because I'm not getting interupts.
My best guess is that I need to load the script to mcu_fw_loader.sh, but after download is successful using the MCU SDK, I can't find any file matching what I named the project or any variant there of anywhere on the edison.
The contents of my script are
/* your configuration code starts here */
while (1) /* your loop code starts here */
mcu_sleep(30000); /* wake up CPU every 5 minutes */
host_send((unsigned char*)"wake up!\n", 10);
The contents of my loader file look like this:
#author: JiuJin Hong (firstname.lastname@example.org)
if [ ! -d "/sys/devices/platform/intel_mcu" ];then
if [ ! -f "/lib/firmware/intel_mcu.bin" ];then
echo "on" > /sys/devices/pci0000\:00/0000\:00\:17.0/power/control
echo "load mcu app" > /sys/devices/platform/intel_mcu/control
I figured it out, "cat ttymcu0" in the example should be cat /dev/ttymcu0
