Is there a dog in my py?

[claus]

Hi all,

I have just received my fipy/pytrack modules and am trying to do run some of the examples. However I get a periodic "reset" signal

rst:0x7 (TG0WDT_SYS_RESET),boot:0x1a (SPI_FAST_FLASH_BOOT)
...

about every 30 seconds and my programs get interrupted and I end at the prompt. I have found out that when I run a program that uses (and feeds) a watchdog timer, everything works nicely. So maybe there is a (watch)dog activated in my fipy? I have tried to install another firmware (1.20.1.r2 instead of 1.20.2.r1) but it didn't help. How can I get rid of this annoying periodic reset?

I have alredy tried the following (this is Ubuntu 20.04), but it does not seem to finish ok.

pycom-fwtool-cli -p /dev/ttyACM0 erase_all
Running in PIC mode
Erasing the board can take up to 40 seconds.
Exception: Timed out waiting for packet content

Any hints?

Kind regards, Claus

and clear the CONFIG and NVS partitions

This seems to fix the problem for me. I had installed fresh firmware bur without resetting these two. Thanks again!

Yes, exactly the same issue! I'll try what is proposed over there, thank you very much!

Hi,
Your issue might be related to this post: https://forum.pycom.io/topic/6412/pycom-board-periodically-restarts

Can you perhaps try to install a fresh firmware and clear the CONFIG and NVS partitions?

Best,
Gijs
