TMS320F28069M: 烧录程序掉电后程序消失

Part Number: TMS320F28069M
Other Parts Discussed in Thread: LAUNCHXL-F28069M

在使用LAUNCHXL-F28069M时,将Boot的三个拨码开关打到HHL时,显示:

Error connecting to the target:
(Error -1135 @ 0x0)
The debug probe reported an error. Confirm debug probe configuration and connections, reset the debug probe, and retry the operation.
(Emulation package 9.4.0.00129)

而在将第三位改为H后,程序在掉电后消失,板子上LED闪烁,为初始例程。

请问该怎么配置可以将代码正确保存到芯片中。

  • 你好,正确的设置是将三个拨码开关设置为HHL,第三个开关对应的是TRSTn引脚,是由仿真器控制的。

    至于出现的这个报错,最好用示波器看下芯片的复位引脚是否有一个复位信号产生?
