To see more debug information add -d to the openocd command line. Hopefully the cause will be revealed in the more information dense output.

Just a guess - is an I2C bus error causing a stall in communication? Are you tracking the status of each I2C call? Does the problem persist after a power cycle to all components (since this will clear the I2C state of all I2C components)? Do you ensure that the I2C communication between the two devi...

Can you trace TX & RX signals at the Esp32 when the radio is switched on? There may be stray noise that interferes with the reception of the serial data. At this low baud rate you don't need a fancy scope.

As a side note: the differences in generated assembly between the two tools are due in part to different scanning algorithms. See e.g. this StackExchange discussion: https://reverseengineering.stackexchange.com/a/2581

All my COM ports are working good but when I connect both in my computer occurs an error.

Not a lot of detail to work with. What is the error message? What software are you using to communicate with the serial ports?

The 5.1 development branch was created in August 2022. Based on previous cycles, it may take about a year to reach a release candidate, then a couple of months of testing the release candidates. So possibly October - December of 2023 would be my guess.

Can you correctly read a fixed voltage (say from a 1.5V battery) on one of the ADC pins to verify that the ADC is correctly configured?

Are you using ADC2? Note these limitations: https://docs.espressif.com/projects/esp ... imitations

I imagine you mean the ESP32 DevKitC v4? That one does not have an USB-to-JTAG bridge onboard, sorry.

Using an FT2232H or FT232H board is not that expensive and works quite well (FT2232H is used on the ESP-WROVER-KIT).

To start, convert the backtrace to source code locations, this way you can at least see more or less where in your code the timeout occurs. See this excellent post on how to convert the code addresses (0x40...) to source code locations: https://esp32.com/viewtopic.php?t=263#p1131 After doing this yo...

Hi,
The header problem is solved now.
CCrause, thank you for your help, you put me in the right direction.

I was facing the almost same problem, thanks everyone for your help.

You are welcome, glad this problem is sorted.
