esp32c6 temperature_sensor: Exceeding temperature measure range after adc_oneshot_del_unit (IDFGH-11828)

[AxelLin]

Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

IDF version.

v5.1.2-534-gbbd8d13f93

Espressif SoC revision.

ESP32C6

Operating System used.

Linux

How did you build your project?

Command line with idf.py

If you are using Windows, please specify command line type.

None

Development Kit.

Custom Board

Power Supply used.

USB

What is the expected behavior?

temperature_sensor should still work after adc_oneshot_del_unit.

What is the actual behavior?

Always got "temperature_sensor: Exceeding temperature measure range" after adc_oneshot_del_unit

Steps to reproduce.

Test using ADC1 ADC_CHANNEL_4.
(Note: it works if using ADC_CHANNEL_2 or ADC_CHANNEL_3, only ADC_CHANNEL_4 has this issue)

Attached the modified code to reproduce the issue , copy it to replace examples/peripherals/adc/oneshot_read/main/oneshot_read_main.c

More Information.

Note, I already manually applied the fix from #12864

[AxelLin]

Just remind v5.1 and v5.2 need this fix.
