Expected behavior

run JTAG debug

Screenshots

use same project configuration, I can debug ESP32C3 chip without inner flash(which use external flash such as GD25Q32)。

untick the mark “Enable memory protection”, but It didn't work.

[erhankur]

In the latest idf 4.4.2 release we updated the OpenOCD version to v0.11.0-esp32-20220411 Can you try with this version?

[sxliujin]

I have update the openocd version to v0.11.0-esp32-20220706. The errors are the same

finally I try to slower the JTAG clock to 10MHz or lower,but it still didn't work.

So, you say with the 4MB internal flash you get this error but external flash is working?

Any chance to upload a test application to reproduce the issue? I will try with the ESP32-C3 DEVKITM-1 . https://docs.espressif.com/projects/esp-idf/en/latest/esp32c3/hw-reference/esp32c3/user-guide-devkitm-1.html

[18506711722]

The same problem occurs in esp32-c3fh4 @erhankur

[erhankur]

I don't see an issue with the idf example applications using boards with 4MB internal flash. If you can send me a small application to reproduce the issue, I can try and comment.

[18506711722]

It has nothing to do with the application, it has something to do with the built-in FLASH. I have two teams, the external flash and the built-in flash @erhankur

[GiulioDallaVecchia]

I have the same issue with my custom board, but with the ESP32C3 DevKit, OpenOCD runs without any problems

[erhankur]

@GiulioDallaVecchia In terms of Jtag and flash pin connections what is the differences with your custom board and Devkit?
Did you run the same application on 2 boards? How can you help me to reproduce this issue?

[GiulioDallaVecchia]

I'm running the same application. This is my openocd command:

openocd -s ${openocd_path}/share/openocd/scripts -f board/esp32c3-builtin.cfg -c "init; halt; esp appimage_offset 0x20000"

Obviously, I'm using D+/D- to connect the board

Is there some problem due to I'm using a custom partition table? I've read that OpenOCD has to read the partition table in order to understand where is the bootloader and application, isn't it?

[erhankur]

@GiulioDallaVecchia can you also share your detailed OpenOCD logs. (with -d3 option)

I want to say that on my custom board we have mounted an esp32c3-mini with external antenna
