not blinking Internal LED in BeagleBone AI

[Farzad]

hi.  I use the Debian 9.12 2020-04-06 on BeagleBone AI.

for the first boot, I go to /var/lib/cloud9/BeagleBone/AI/pru directory and run

root@beaglebone:/var/lib/cloud9/BeagleBone/AI/pru# source setup.sh
TARGET=blinkInternalLED.pru1_1

and run make command

...

every things is fine and start blinking Internal LED.also /sys/class/remotproc/remotproc1/state is "running" and
/sys/class/remotproc/remotproc1/firmware is "am57xx-pru1_1-fw"

but

after reboot and run previous commands to make blinkInternalLED.pru1_1.c ,make is complete but internalLED not blinking and 
/sys/class/remotproc/remotproc1/state is "suspended" also /sys/class/remotproc/remotproc1/firmware is "dra7-ipu1-fw.xem4" :|

Why is this happening? However, this is not the case for BeagleBone Black with the same image??

Thanks for any suggestions,

Best regards,

On the am57xx family there are many more "remoteproc" devices, the
script used "remoteproc1" but you referenced "remoteproc0".. We are
working on symlinks to fix this confusion, but it hasn't shipped yet.

It was my mistake.but remotproce1 also gives the same error. In fact, all remotproce 0-3 state is suspended with and 4-7 state is offline.

debian@beaglebone:~$ cat /sys/class/remoteproc/remoteproc5/state

Why remotproce0-3/firmware have changed by remotproce4-7/firmware that are in the first boot??
