I am new to STM32. I've been trying to program my Nebula 2.0 to, say, blink LED5 every 500ms. I've tried to do this with STM32 Cube IDE, which is STMicro's IDE (I've resorted to this because I did not manage to open WICED on my mac, due to an error). I've tried setting the debugger to ST-LINK(OpenOCD) but it cannot detect a matching adapter. Could it be because the board does not support ST-LINK-v2?
You can find the installation notes for MAC here WICED-Studio 6.4.0 Installer (OSX). Please follow them and you should be able to find out.
There is no ST-Link onboard with the Nebula 2.0 so definitely it won't be able to find that. USB-UART --> FT2232H --> JTAG of STM32F429
