ESP-IDF 4.2 reset on radio

Postby duncairn » Mon May 04, 2020 4:57 pm

I have a project using an Wroom-32 which I developed using ESP-IDF 4.1 and the legacy build tools (i.e. msys2). But 4.1 is behind the times so I tried moving up to 4.2 (legacy tools with 4.2 Dev and Cmake with 4.2 relaese). With any 4.2 version the Wroom resets as soon as I enable Bluetooth:
I (13186) BLE: Starting nimble
I (13186) BTDM_INIT: BT controller compile version [d9cc6b1]
I (13196) system_api: Base MAC address is not set
I (13206) system_api: read default base MAC address from EFUSE
W (13226) phy_init: failed to load RF calibration data (0xffffffff), falling back to full calibration

Apologies for the length of this post!

Anyway, you'll take one look at that and consider it's a power issue (yes, I did a lot of searching on this issue). However, I think that's a red herring because a) the code and hardware works perfectly well using IDF 4.1. In fact, I tried turning on WiFi and BLE on the Wroom and simultaneously a GSM modem (now there's a power sucker) and simultaneously a string of LEDs using ~100mA, and with IDF 4.1 it works fine. But 4.2 kills it if I just turn on BLE.

Another thing: I can run the example BLE apps with 4.2, just not my code. For reference, with 4.1 this is what happens:
I (10792) BLE: Starting nimble
I (10792) BTDM_INIT: BT controller compile version [6decaaf]
I (10812) system_api: Base MAC address is not set, read default base MAC address from BLK0 of EFUSE
I (11062) phy: phy_version: 4102, 2fa7a43, Jul 15 2019, 13:06:06, 0, 0
I (11312) BLE: host task started
I (11312) gatt_svr: registered service 0x1800 with handle=1
I (11312) gatt_svr: registering characteristic 0x2a00 with def_handle=2 val_handle=3
So, my supposition is that my code uses something that changed between 4.1 and 4.2 that causes this issue, and most likely that something isn't used by the simple example apps (or, at least, not triggered by them). How do I find out what that thing is?

Ah, and someone will pop up and say it's the partition size. I changed that too without success. However, the failure mode did change:
I (20286) USER: new state: waking
I (20286) BLE: Starting nimble
I (20286) BTDM_INIT: BT controller compile version [d9cc6b1]
I (20296) system_api: Base MAC address is not set

Both the above are repeatable, BTW. That is, the results are not flaky but give the same thing every time.

Did you run a 'git submodule update' when you updated esp-idf? Could be that the libs are out of sync. (Also, fancy colors in the listing!)

Yep, did the update, mostly because I wanted to be sure the updated nimble module was there, and it was easier to update the lot than just that :)

If anyone is still interested in this, I think I found the cause...

It is rmt! Yes, nothing to do with radio at all. Just a coincidence that my project uses rmt to drive a bunch of LEDs which come on a little before the radio is connected. It takes a couple of seconds for rmt to overwrite memory, hence why there is no sensible crash report and it looks like a hardware power issue.

This is something that's occurred in 4.2 (maybe 4.1 - didn't try). If I copy rmt.c and rmt.h from 4.0 I don't get a crash. Unfortunately, there are a LOT of changes in 4.2 and it's beyond me to figure out what's going on. I know the function though: rmt_fill_memory().

Interesting. Any chance you could whittle down your project into something small that still exhibits the behaviour?

I am facing similar issue when migrated from v4.0.1 to v4.2
The device reboots almost every 10sec
Attaching a very basic code with sdkconfig from original project. So, I am guessing, it's something in sdkconfig

Here is the log

It is the RTC watchdog causing this problem.

Possible solutions:
  • Disable RTC watchdog: Bootloader config->Use RTC watchdog in start code
  • Increase RTC timeout Bootloader config->Timeout for RTC watchdog
  • Feed RTC watchdog: import "soc/rtc_wdt.h" and invoke "rtc_wdt_feed();" periodically
Check this thread for more details: https://github.com/espressif/arduino-esp32/issues/2230

For me, everything was working fine with esp-idf v4.0.1 but had to do above changes when using esp-idf v4.1 and above
