I am trying to override the SD card in the ST25R3911B NFC Board from Waveshare so I can send a bmp file via USB. I am using an example from the STM32F103RB pack: "USB Device Mass Storage" (which I am not even sure that is correct). When trying to build the target, it states I don't have the correct compiler version. How do I download this version? Also if this is the incorrect pack, please let me know if you have any insight.
