We did a fix regarding ESP32-S3 flash read failure in the latest OpenOCD release. Please try with https://github.com/espressif/openocd-esp32/releases/tag/v0.12.0-esp32-20240821

Can you add additional command to the end of OpenOCD start script?

openocd ..... -f board/esp32s3-builtin.cfg -c "esp stub_log on"

You should see a logs something like;

[erhankur]

Thanks.

Error is Unsupported octal flash manufacturer I will check this internally and come back.

In the meantime you can skip flash support by adding -c "set ESP_FLASH_SIZE 0" command just before the board config file.

[microfoundry]

Thank you for looking into it.

With regards to it being Unsupported octal flash manufacturer , as I posted in the Arduino IDE issues, I do find it interesting the return value:
STUB_D: flash c28039, cs 2000000, bs 10000, ss 1000, ps 100, sm ffff
c2 = the one octal flash mfg code that is utilized in the logic
and LSBs 39 = 32MB
Just saying...

[erhankur]

One more thing; Can you enable PSRAM support from the menuconfig and try again?

[microfoundry]

I have PSRAM enabled as required for my app. But I believe the simple memory/debug tests I was performing against the various ESP modules was without.

[erhankur]

I found a board and tried. Worked as expected.

STUB_D: flash c28039, cs 200000, bs 10000, ss 1000, ps 100, sm ffff
STUB_D: Flash ID read 3980c2
STUB_D: Flash ID 39, size 32768 KB
STUB_D: stub_flash_get_map: 0xffffffff 0x3fca28f4

Please enable PSRAM in your simple tests as well and share the results. If it works, I’m afraid we will need to revisit that fix.

[microfoundry]

This all started with the issue being raised in the Arduino Core project as I'm working within the Arduino IDE and the debugger failure to attach to the 32MB module. But a point was made in that thread to bring it to y'alls attention. Now with regards to the "enable PSRAM" request, it would seem that within the current ver of Arduino Core, selecting MCU ESP32S3-WROOM-2 will set the memory to Octal and enable Octal PSRAM. And If the flash is left on Octal, changing the PSRAM setting to anything other than Octal produces an error when compiling. Additionally, Picking a std ESP32S3 Dev Module will (not surprisingly) produce the same results.

Regardless of all that, my project at hand does have PSRAM enabled and the app currently utilizes ~30%. So I can say with it on, the attempt to launch OpenOCD fails the same way.
