linux - Mspdebug 收不到数据

Question

我正在尝试学习微 Controller 编程。我从 msp430 开始，我已经安装了 mspdebug 0.18 和 mspgcc 4.5.3。我想加载一个简单的程序到设备上进行测试，但 mspdebug 无法通过删除设备。

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...  
rf2500: can't receive data: Resource temporarily unavailable  
fet: erase command failed  

Output of dmesg after unplugging and plugging in the device:

这与删除在 FRAM 芯片上不起作用(或至少不能正常工作)有关。您应该更新到最新版本的 mspdebug ( http://mspdebug.sourceforge.net/)，它会处理这个问题。
