Unable to program ESP32-SOLO-1

[ajaykk]

I am unable to program ESP32-SOLO-1 using JTAG on the ESP-WROVER-KIT v3.

JTAG Connections:-

also, I enabled single core mode in menuconfig.

openocd output:-

** Unable to reset target **

BTW i am able to program the ESP32-DEVKIT-C-V4 using the same method without any problems. The issue is only with SOLO.

[ESP_Sprite]

Fwiw: 'Error: JTAG scan chain interrogation failed: all ones' usually means there's something wrong on a very low level: the JTAG adapter physically cannot talk to the JTAG hardware. Are you sure the SOLO-1 does not have a program in it that reconfigures the JTAG pins for something else?

[ajaykk]

This is a fresh module and first time programming it.

can you give us proper connection details and configurations for this module?

EDIT:
Below shown problem is solved by keeping the BOOT button pressed while the firmware is downloaded.
I read about similar problems with cheap Chinese dev boards, but this board is an original Espressif DevKitC-S1.
Was not expecting a bad HW design from Espressif.

-------------- SOLVED --------------
Similar problem here. ESP32-SOLO is showing on serial port, I can get debug output when starting the module.
Get as well the

Code: Select all

rst:0x1 (POWERON_RESET),boot:0x3 (DOWNLOAD_BOOT(UART0/UART1/SDIO_REI_REO_V2))
waiting for download

when pushing EN and BOOT.
But when I try to flash the module I get only

A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header

Where did you find single core mode in menuconfig? I cannot find this setting.
Do I need different toolchain or have to clone a different ESP-IDF version to flash the SOLO?
Or do I need extra settings in make?

[ajaykk]

My esp-solo module was faulty. I tried with another solo module, was able to flash program using serial bootloader but when trying with JTAG, I am getting this message:-

You don't need anything extra, this setting is under > Component config > FreeRTOS

[beegee1962]

Thanks for your feedback.
I found the settings in menuconfig already.
But still have the problem that I need to push BOOT button while flashing over USB.
Don't have a JTAG adapter (yet), so I cannot test flashing over JTAG.
