ESP32 JTAG Debugging with 2 used SPI buses

Postby willpowell » Tue Jul 12, 2022 12:59 pm

I have just got myself an ESP-Prog debugger to remove the horrible Serial.print debugging process. https://espressif-docs.readthedocs-host ... guide.html

This uses JTAG and therefore requires wiring to SPI . However, I am already using the two SPI Devices (hSPI and vSPI) which are constantly requiring communication (writing to SD card and reading ADC). I don't want to sacrifice speed by putting them on one bus and toggling the chip select. I am also multithreading, so it's hardly an easy fix.

Is there any way to connect the JTAG pins in parallel with either the hSPI or vSPI?

Any other suggestions would be much appreciated.
Thanks, Will.
