The only TERRIBLE thing is that with the update to the latest version they ...

Yesterday I made the mistake of updating the toolchain to version 5.4, which is not fully compatible with VisualGDB. After doing so, I tried to install version 5.3. When compiling the toolchain, an error is thrown on the usb_dwc_hal.c file. The error is in the included file usb_dwc_ll.h at line 224 ...
