Silicon Labs EFM8/C8051: main() never executes. It seems that the reset is happening repeatedly. How should I deal with this?
It is suspected that a watchdog timer (WDT) reset has occurred.
When using the KEIL compiler, initialization is done by STARTUP.A51 before main() is executed. This initialization routine also initializes the RAM, but if the MCU has a large RAM size, initialization takes time. Since the Watchdog timer is enabled by default, the Watchdog timer overflows during initialization and causes a reset.
A workaround is to disable the Watchdog timer at the beginning of STARTUP.A51.
