Hello,
I have changed the
hello_watchdog.cexample to detect only reboot caused by watchdog.I have used the original example program and there was a wrong detection of watchdog caused reboot. For example, when a program was load on the RP2040 through uf2 file, then the RP2040 restart and the
result of watchdog_caused_reboot()istrue.I have changed it to
watchdog_enable_caused_reboot()cause based on the documentation found here.I have tested it on my own project, the detection was fine without detection of reboot caused by program upload, that is why i do a pull request to help others to use watchdog.
