IAR 5.5 仿真出错

用IAR5.5 首次下载提示,固件升级,升级后提示

Thu Jul 17, 2014 18:01:51: Firmware version 30204005 
Thu Jul 17, 2014 18:01:51: Interface dll version 3.2.4.5 
Thu Jul 17, 2014 18:01:55: Unknown device 
Thu Jul 17, 2014 18:01:58: Fatal error: Could not find device (or device not supported) Session aborted!

  • 很明显是单片机开发板和电脑的并口没有连接好,可以拔下来并关闭烧写软件,尝试重新连接。如果还不能解决,也可以尝试重启电脑试试,刷新固件后有时重启也能好用。

  • 我用的是TI的 MSP-FET430UIF仿真器,在通过JTAG连接到要下载程序的板子,仿真器与电脑室通过USB连接的呀,关闭烧写软件是关闭IAR吗?

  • 可能是升级不成功导致的,降级试一下,具体操作看这边:  http://www.deyisupport.com/question_answer/microcontrollers/msp430/f/55/t/8373.aspx
