Problem Description

1. I've been following the VSCode tutorial at https://github.com/espressif/vscode-esp-idf-extension/blob/master/docs/tutorial/basic_use.md
2. When I select JTAG as the flashing method and try to flash, I see the following message in the openocd console:

3. UART flashing works fine.
4. If I flash via UART, then try to debug via JTAG, I just get a pop-up error message saying "Failed to init Debug Adaptor", and the openocd console shows:

5. I thought this might be related to ❌ Error: Failed to get flash size! (OCD-546) #215, but I JTAG flashing and debugging fails 100% of the time with the blink project.

Debug Logs

When I manually run OpenOCD as `openocd -d3 -f board/esp32s3-builtin.cfg` and try to debug with gdb the logs are too long for github, but can be downloaded here https://drive.google.com/file/d/1ArEICuVxiwI2_Hi_CGY3RdiQSSlcBjDK/view?usp=sharing

Expected behavior

To be able to flash and debug code in VSCode.

@brentalanmiller What is the flash size of your board?

[brentalanmiller]

@erhankur It's the 32MB version.

[erhankur]

I assume it is esp32-s3-wroom-2-n32r8v with the octal flash. If yes, 32MB octal flash support added to master branch and not released yet. We are planning to release soon.

If you don't want to wait for release I can send the binary for your tests. (Just tell me which OS are you working on)
Or you can easily build from the source on linux.

[brentalanmiller]

@erhankur thanks for the info and yes, I have a ESP32-S3-WROOM-2-N32R8V. (Sorry, I should have included that in the initial report.)

I just checked out and built master at 554a6c2 and now I can flash and debug via JTAG.

Thanks again! Appreciate the help.

For those who have a building issue from the source on windows.

I'm having this same issue, on an M1 Mac (aarch64). any chance you have the binaries kicking around for me? compiling from source isn't working for me.
