Cannot enable pull-up on GPIO25 (input)

[be-20-bb]

I'm trying for hours here enabling the pull-up on GPIO25 when in input mode.

I came across a bug report that said for some GPIOs, the pull-up had to be set by modifying the RTC GPIOs instead, and a fix was submitted to the IDF to make this workaround transparent for the users of ESP-IDF:

However, nothing is working for me:

Code: Select all

   	gpio_pad_select_gpio(MY_GPIO);
	gpio_set_direction(MY_GPIO, GPIO_MODE_DEF_INPUT);
	gpio_set_pull_mode(MY_GPIO, GPIO_PULLUP_ONLY);
	rtc_gpio_pullup_en(MY_GPIO);

Any ideas?

I'm using the WROOM-32 module. The pin works fine as an output, and there is no electrical connection with the pin that could interfere.
