Hi, has anyone tried JTAG debugging with OVMS? Mainly interested in having settable breakpoints (a feature which doesn't seem to be possible with UART gdb stub in ESP32, but seems to work with ESP8266. See https://visualgdb.com/tutorials/esp8266/gdbstub/ ). There's no JTAG header on OVMS, but I'm willing to solder a JTAG connector directly to ESP32 pins. But those pins are already connected to the SD-card reader.. Is not having a sd-card in the slot enough, or does the initialization mess with the debugger connection, thus needing to disable the sd card module on firmware? Or do I have to desolder the reader? (last resort) Br, Marko
