    I have a custom board with an ESP32-WROOM-32D module. It was programming and debugging just fine using the TumpaLite FTDI board. After updating to VGDB 5.6R4 and IDF4.4 I can no longer program via JTAG unless I reset into the bootloader first. Logs follow…

    Log after manually resetting the ESP32 into serial bootloader mode (this works despite the warnings).

    Hi,

    This looks like an issue between the module and the Espressif’s port of OpenOCD, and hence is not directly controlled by VisualGDB. Please consider contacting Espressif for further help with this issue.

    You can also try reproducing it by manually running the OpenOCD build from the Espressif github repository. It it works better, we can help you configure VisualGDB to replicate the correct behavior.

    Update: we got another report of a similar issue in this thread, and the workaround suggested on the Espressif forums is to pass the “esp appimage_offset 0x20000” command to OpenOCD. With VisualGDB, this can be done by adding the following text to the end of OpenOCD command line in VisualGDB Project Properties -> Debug Settings -> Advanced:

    -c "esp appimage_offset 0x20000"
