CC2538dk can't properly reboot !!!

Would you specify what fw you flash into CC2538? If you use SampleLight or SampleSwitch, the difference might be caused by NV_RESTORE.

Contiki 2.7 application

Sorry! I am not familiar with Contiki and can't help you.

Hi YiKai

Frankly speaking, I didn't properly understand your message.

After all, the firmware from TI or a custom application, based on Contiki staff ... both finally are "transformed" in a flash file by a compiler. It's up to compiler to properly "map" the program code. I thought, that impact of the "RESET" button is the same as one of "releasing board after flashing". Isn't it ?

Probably should I examine more attentively the compiler options ?

If so, which ones ?

Basically, I don't work on Contiki. From my experiences on Zigbee HA using CC253x, NV_RESTORE will make reboot have different behavior. If NV_RESTORE is enable on Zigbee device, the device will keep the previous network status. When it reboots, it will try to join the original Zigbee network. If not enable, the device will start like a new one to find new Zigbee network when it reboots. I suspect there is some compile option similar to NV_RESTORE on Cntiki. You can try to find if this is the case.

Ok, thanks YiKai.

Now it's more clear. Unfortunately I didn't find the flag NV_RESTORE (or something like this) in Contiki staff.

Moreover, my case ia slightly different: when I Pöower OFF/Power ON the device, its behavior looks like that after reboot with reset. So, the only way to make work CC2538 properly is to reflash it !

What where the behavior on Power OFF/Power ON in your case ?

In my application, the device will restore to previous status after I power off/ power on it.

So,

"Power ON/Power OFF" == "Just after flash"

Correct ?

Yes, it is in my application.
