TI中文支持网下载AM335xBluetopiaLinuxProduction-4.0.3.0.1.0后 ，
修改了setup-bt 的
# Path to local toolchain installation export TOOLCHAIN_PATH=~/ti-processor-sdk-linux-am335x-evm-03.02.00.05/linux-devkit/sysroots/# Path to SDK compiled kernel export KERNEL_PATH=~/ti-processor-sdk-linux-am335x-evm-03.02.00.05/board-support/linux-4.4.32+gitAUTOINC+adde2ca9f8-gadde2ca9f8/
修改其中的build/proj toochain-defs.mak文件中的
TOOLCHAIN_PATH_NATIVE=$(TOOLCHAIN_PATH)/x86_64-arago-linux/ TOOLCHAIN_PATH_TARGET=$(TOOLCHAIN_PATH)/armv7ahf-neon-linux-gnueabi/
在build目录下make出现：
LinuxHFRM_AG.c:(.text+0x4bcc): undefined reference to `PM_VS_DisableWBS'
LinuxHFRM_AG.c:(.text+0x5c48): undefined reference to `PM_VS_EnableWBS'
collect2: error: ld returned 1 exit status
make: *** [../BluetopiaPM/bin/LinuxHFRM_AG] Error 1
此错误是否和上面的路径有关？？
求大神解答
Viki Shi：
你用的是什么蓝牙芯片，wilink？

Eggsy Pang：
回复 Wayen zhang:
DEVM_PowerOnDevice() Failure代表CC2560还没上电或者引脚使能，看到你用45号 引脚来使能它，有没有测过这个引脚的电压？
Wayen zhang：
回复 Eggsy Pang:
测过 ，对这个gpio写1电压测得3.3v。写0时变为0V。
2560b 可以用这个蓝牙协议栈版本么——TI Bluetooth Linux Add-On for AM335x EVM, AM437x EVM and BeagleBone With WL18xx and CC256x（v4.0.3.0.1.0 ）http://www.ti.com/tool/TI-BT-STACK_LINUX-ADDON
256xc可以直接替换2560b么 ？
Eggsy Pang：
回复 Wayen zhang:
可以用这个版本，
但是CC2560的所有IO是1.8V的，给3.3V是有问题
da qin zheng sheng：
回复 Wayen zhang:
串口波特兰率很高啊！
Wayen zhang：
回复 Eggsy Pang:
io是1.8， 3.3是经过一个电平转换后测量的值。出现这种错误和gpio关系最大？
Wayen zhang：
回复 da qin zheng sheng:
波特率设过115200，问题依旧出现
