Because my last board became unresponsive and any attempt to reboot it failed, I got a new board. Unfortunately I am having the same sort of issues as last time. I will upload my config below.
aniwani_config.h (62.3 KB)

Arduino: 1.8.3 (Mac OS X), Board: “Proffieboard V2, Serial + Mass Storage + WebUSB, SDCARD (SPI), 80 MHz, Smallest Code”

Board ProffieboardV2-L433CC (platform stm32l4, package proffieboard) is unknown

Error compiling for board Proffieboard V2.

This report would have more information with
“Show verbose output during compilation”
option enabled in File → Preferences.

I keep getting this error message.

This means that the arduino-proffieboard plugin is not properly installed. Please (re-)install it.
