ESP-IDF component (RMT) debugging

Hi,
right now I'm debugging an application implementing an RMT led strip. Unfortunately I cannot debug rmt_tx.c a.t.l as obviously there are no debug symbols for this standard components. I can set a breakpoint, that works, but of course no watch expressions and no local variables e.a. I suspect ...

API to get CPU frequency

Hi,

did a search but keep getting HTTP ERROR 500, so I ask here.
It there an ESP-IDF API function to get the current CPU frequency?
Thanks

Re: ESP32-S3 GPIO3 does not select external JTAG when low

Hi there,

thx. I am experienced in programming but new to ESP32 (came from STM32), so please bear with me :)

I did find DIS_USB_JTAG and DIS_PAD_JTAG, but not STRAP_JTAG_SEL.

This is my efuse summary:

Re: How to detect a cause of interrupt on GPIO (rise or fall) ?

I use method 1.
There is no need to read the GPIO via ADC. Simply use gpio_get_level(gpio_num_t gpio_num).

ESP32-S3 GPIO3 does not select external JTAG when low

Hi team,

this is my first post here.

I want to use ESP32-S3 with an external JTAG (ESPPROG). So I strapped GPIO3 to GND as documented.
Nevertheless, the external JTAG does not work. The connections are correct, and my ESPPROG worked ok with ESP32.

Any ideas appreciated.
