Question

我正在努力学习编程微控制器。我从msp430开始，我已经安装了mspdebug 0.18和mspgcc 4.5.3。我想将一个简单的程序加载到设备上进行测试，但mspdebug无法通过擦除设备。

Device: MSP-EXP430FR5739  
Computer OS: Ubuntu 12.04 LTS  

Error Messages:  
Trying to program device:  
(mspdebug) prog led.elf  
Erasing...  
rf2500: can't receive data: Resource temporarily unavailable  
fet: erase command failed  

Trying solely to erase device
(mspdebug) erase  
Erasing...

Output of dmesg after unplugging and plugging in the device:

这与在FRAM芯片上擦除不工作（或至少不像往常一样工作）有关。您应该更新到最新版本的mspdebug（http://mspdebug.sourceforge.net/）来处理这个问题。

Mspdebug无法接收数据
