如题，使用的最新的源码，在k210的bsp下配置好工具链
官网直接下载的编译工具链：[https://kendryte.com/downloads/](https://kendryte.com/downloads/)

后直接scons编译报错，如下为编译报错（后面很多重复的没有截取了）：

```
可以看出是在链接rtthread.elf的时候报的错，具体原因为：
`can't link hard-float modules with soft-float modules`

初步怀疑可能是编译的时候flag设置错了，以下为工程的`rtconfig.py`配置文件：
```python
import os

# toolchains options
ARCH        ='risc-v'
CPU         ='k210'
CROSS_TOOL  ='gcc'

if os.getenv('RTT_ROOT'):
    RTT_ROOT = os.getenv('RTT_ROOT')
else:
    RTT_ROOT = r'../..'

# if os.getenv('RTT_CC'):
#     CROSS_TOOL = os.getenv('RTT_CC')

if  CROSS_TOOL == 'gcc':
    PLATFORM    = 'gcc'
    # EXEC_PATH   = r'/opt/gnu-mcu-eclipse/riscv-none-gcc/8.2.0-2.1-20190425-1021/bin'
    EXEC_PATH   = r'E:\RT_Thread_Env\tools\gnu_gcc\kendryte-toolchain\bin'
else:
    print('Please make sure your toolchains is GNU GCC!')
    exit(0)

# if os.getenv('RTT_EXEC_PATH'):
#     EXEC_PATH = os.getenv('RTT_EXEC_PATH')

BUILD = 'release'

if PLATFORM == 'gcc':
    # toolchains
    # PREFIX  = 'riscv-none-embed-'
    PREFIX  = 'riscv64-unknown-elf-'
    CC      = PREFIX + 'gcc'
    CXX     = PREFIX + 'g++'
    AS      = PREFIX + 'gcc'
    AR      = PREFIX + 'ar'
    LINK    = PREFIX + 'gcc'
    TARGET_EXT = 'elf'
    SIZE    = PREFIX + 'size'
    OBJDUMP = PREFIX + 'objdump'
    OBJCPY  = PREFIX + 'objcopy'

DEVICE  = ' -mcmodel=medany -march=rv64imafdc -mabi=lp64d'
    CFLAGS  = DEVICE + ' -fno-common -ffunction-sections -fdata-sections -fstrict-volatile-bitfields'
    AFLAGS  = ' -c' + DEVICE + ' -x assembler-with-cpp'
    LFLAGS  = DEVICE + ' -nostartfiles -Wl,--gc-sections,-Map=rtthread.map,-cref,-u,_start -T link.lds'
    CPATH   = ''
    LPATH   = ''

if BUILD == 'debug':
        CFLAGS += ' -O0 -ggdb'
        AFLAGS += ' -ggdb'
    else:
        CFLAGS += ' -O2 -Os'

CXXFLAGS = CFLAGS

DUMP_ACTION = OBJDUMP + ' -D -S $TARGET > rtt.asm '
POST_ACTION = OBJCPY + ' -O binary $TARGET rtthread.bin ' + SIZE + ' $TARGET '
```

求大佬指点一二
