How we can access ADC/DAC pins from MT76xx main SoC ?
They are connected to GD32 sub MCU.

Yes, the GD32 connect to VoCore2 by TXD2/RXD2, you need to write new firmware to GD32, and read data from TXD2/RXD2. But same time you will not able to use CDC(USB2TTL) unless you copy back old firmware.

I was considering buying a Vocore2 to play with the analog inputs... do you have firmware for the GD32 that enables access to the analog IO? I did not see the sources anywhere.

GD32 firmware you need to download from gd32mcu.com
Then you can use serial port communicate with vocore.
