Using ESP-Prog in VSCode with PlatformIO

Postby sidprice » Mon Jun 27, 2022 3:27 pm

I am having trouble getting reliable operation with ESP-Prog, ESP32-CAM when uploading using JTAG.

Here is the thread in the PlatformIO Community Forum that explains the issue:

Thank you,
Sid

Hi sid,

Sorry for late reply.
I see that you use 500 KHz adapter clock. Do you have any special concerns on not using default 20 MHz clock?

Regards
Alexey

Yes, I use the lower frequency because at 20MHz the same issues occur.

Ok.

1) Could you provide information about IDF and OpenOCD versions you use?
2) What is the exact wire connection between ESP-Prog and board? Do you connect ESP-Prog's UART to module's one?
3) How board is powered up?
4) What ESP32 module do you use on ESP32-CAM and ESP32-devkitC?
5) Does problem happen reliably (for example every other run)? Any hints to reproduce it reliably?
