Environment

Development Kit: ESP32-Wrover-Kit
Kit version : v4.1
Module or chip used: ESP32-WROVER-B
IDF version (run git describe --tags to find it): v4.3-beta1-24-g0bbc721a6
Build System: idf.py
Compiler version (run xtensa-esp32-elf-gcc --version to find it): xtensa-esp32-elf-gcc (crosstool-NG esp-2020r3) 8.4.0
Operating System: ubuntu 16.04
(Windows only) environment type:
Using an IDE?: No
Power Supply: USB

Problem Description

I refer : https://github.com/espressif/esp-idf/issues/947#issuecomment-500312453 to enable 32kHz to save more BLE power consumption.

it work on esp-idf (branch 4.2) But it not work on esp-idf (branch 4.3)

I use scope to measure IO32 or IO33. there is no 32KHz on esp-idf (branch 4.3).

32k on branch 4.2 tek00122

no 32k on branch 4.3 tek00123

Expected Behavior

32kHz exteral crystal should work on esp-idf 4.3 .

I can not confirm that the crystal is not working correctly, but I can confirm that with this branch the BLE on light sleep is not working correctly (it works on 4.2) and everything points out that the problem is the external 32kHz crystal, it also doesn't work with the master branch

I'm seeing this same issue, with multiple units. I have been using 4.2 until recently, when I upgraded to 4.3, causing most (but not all) units to stop executing code and then crashing, leaving the device stuck as reboot does not seem to function either.

Having downgraded to 4.2, my units again work well with the external 32k crystal.

@MisterScience5 @wolfstrassen @ubntpeter Do you still hit the issue with latest v4.3.4 release?

I'm sorry, I haven't tried the 4.3.4 release
