Posted on September 03, 2013 at 16:47I appreciate any help Thanks
A tracker with STM32L151 began to have a bug even with the watchdog enabled. The crash always occurs when the modem gsm this broadcast.
We created a test version that only flashing a gsm modem led is off and in this case there was no bug.
Put trackers that transmit near that model with the LED and the bug only occurred again.
Put a protection against electromagnetic interference shield this model with LED and the bug no longer occurs.
The problem is that even with the watchdog triggered STM32l151 not return to work, we suspect that it is something related to the pin boot.
Anyone have any other ideas or suggestions,
Edson
