Build errors

[csurf]

I'm having trouble building the bootloaders.

I downloaded the repo, and updated the platformio.ini file to point to 'toolchain-gccarmnoneeabi@1.40804.0' in order to pull gcc 4.8.4.

I'm getting errors like the following:

../.platformio/packages/toolchain-gccarmnoneeabi/bin/../lib/gcc/arm-none-eabi/4.8.4/../../../../arm-none-eabi/bin/ld: .pio/build/gd32f1-frankenmaple/firmware.elf section `._usrstack' will not fit in region `RAM'
../.platformio/packages/toolchain-gccarmnoneeabi/bin/../lib/gcc/arm-none-eabi/4.8.4/../../../../arm-none-eabi/bin/ld: region `RAM' overflowed by 92 bytes

ALL of the builds fail.

also getting the following warnings:

dfu.c: In function 'dfuCopyState':
dfu.c:379:9: warning: return discards 'volatile' qualifier from pointer target type [enabled by default]
         return (&(dfuAppStatus.bState));
         ^
In file included from usb_lib/usb_lib.h:21:0,
                 from usb.h:28,
                 from common.h:40,
                 from usb_descriptor.h:28,
                 from usb_descriptor.c:35:
usb_lib/usb_type.h:23:14: warning: initialization makes integer from pointer without a cast [enabled by default]
 #define NULL ((void *)0)
              ^
usb_descriptor.c:201:28: note: in expansion of macro 'NULL'
 u8 u8_usbStringInterface = NULL;

The reason I need to build is because I need a bootloader for the NAZE32 rev5 board which has a 12MHz xtal (your build is apparently for rev4, with the 8MHz xtal, and it doesn't work).

Normally this is not built within Platformio

The errors you are experiencing look like problems with compiler options, and the makefile sets all this correctly for it to build
