I can’t find the latest ESP32/ESP8266 toolchain in the VisualGDB package list, though I can see them in https://gnutoolchains.com/esp8266/ and https://gnutoolchains.com/esp32/.
I can find only old packages there.
I use VisualGDB version 5.5R3 (build 3898).
Could you help?
Most likely, you have already installed the latest versions of the toolchains, so they will appear in the Installed view, but not in the Online view. Please try double-checking both views.
