Bug description

We have a custom PCB with an ESP32C6-WROOM-1-N8 module.
We already have firmware based on esp-idf-svc 0.49 and esp-idf v5.1.3 that flashes and runs just fine on this PCB.

However, we would like to update to the latest version of esp-idf-svc, and are running into a bootloop with even just a sightly adjusted sample from the esp-idf-template to match the increased flash size: https://github.com/thedevleon/esp-idf-issue-bootloop

Running 'cargo run --release' results in the following looping output only:

  • Would you like to work on a fix? y

To Reproduce

  • clone the repo above
  • connect a devkit with the WROOM-1-N8 module (via the native USB port, not UART)
  • cargo run --release
  • observe the looping output

Expected behavior

I can see a hello world printed and the output of the bootloader.

Environment

  • Crate (esp-idf-svc) version: 0.50
  • ESP-IDF branch or tag: v5.3.2
  • Target device (MCU): esp32c6
  • OS: Fedora Workstation 41

Further notes:

  • Putting the ESP into bootloader mode first, and then flashing just results in a "waiting for download" message, even after the flash and after resetting via CTRL-R
  • Resetting via CTRL+R or via the EN pin doesn't help
  • any attempt to monitor after the initial espflash --monitor from cargo run will result in a timeout

How is that a problem with the new ESP IDF given that you can't even load and start the ESP IDF bootloader?

I don't quite understand what you mean. Can you elaborate? I don't know why the bootloader doesn't load either. All the configuration around the bootloader and partition layout is the same between our current firmware with the old esp-idf(-svc) version and the new sample with the new esp-idf(-svc)version. Why would one boot and not the other?

I have no idea because I have no detailed information for your configuration. What I'm saying however is that you are very likely looking at the wrong place. Your esp-idf-test (old or new) starts executing at millisecond 209 or so in your log. Everything before that is the ROM bootloader and then the 2nd stage bootloader flashed by espflash (as you are not flashing a custom one). So it sounds pretty much impossible the culprit to be the new esp idf 5.3, given that the esp idf 5.3 new code does not even get the chance to be loaded, let alone executed.

I just generated a new project using cargo generate, but chose the v5.2 esp-idf sdk instead of the v5.3 and that boots and flashes fine... So at least from my view, that's the only difference and thus the culprit, wouldn´t you agree?
So for now we'll stick with ESP_IDF_VERSION = "v5.2.3".

  • I just generated a new project using cargo generate (full logs below), flashed on the c3 c6 and it works.
  • I also tried to explain why I find the new ESP-IDF 5.3 support to be the least likely of all possible options (really, and again sounds theoretically impossible).

There are other more likely (IMO) possibilities:

  • Brownout (though too early for that, usu. happens when Wifi kicks in) have you tried with more powerful USB power supply?
  • Buggy board. Perhaps you should google why you get the TG0_WDT_HPSYS triggered for your board
  • Old/buggy espflash

So for now we'll stick with ESP_IDF_VERSION = "v5.2.3"

Sure, up to you.

In all fairness, the log from above ^^^ was for ESP IDF 5.2.3 as apparently this is still the default. Yet - I took the effort, re-generated a completely new project, went to advanced settings, made sure I select "5.3.2", built, flashed, ran. Same result.

If you want to get to the bottom of this, googling for TG0_WDT_HPSYS early during bootup might be key.
