The controller has detected a target power loss.

Other Parts Discussed in Thread: TMS320F28069, TMS320C6657

Error connecting to the target:
(Error -180 @ 0x0)
The controller has detected a target power loss.
The user must turn-on or connect the power supply for the target.
(Emulation package 5.1.73.0)

我是TMS320F28069,TQFP100,按照controlSTICK的电路原理图去做板子,供电传输距离不是问题,只有7平方厘米的小板子,EMU0,EMU1上拉了,TRST下拉了.电阻,EMU0,EMU1的上拉电阻是10k,供电是5V,带3.6V的LDO.

  • 原理图呢?特别是电源和JTAG部分的。

    有测量电源引脚电平是正确的吗?

  • JTAG的TRST是3.3K下拉,EMU0,EMU1是10K上拉.电源电平保持在3.3V~3.5V.

  • 请先按照datasheet 5.7 Emulator Connection Without Signal Buffering for the MCU更改JTAG部分线路测试一下,然后确保电源稳定在3.3V左右:

  • 我也遇到了类似的问题,我用的是TMS320C6657,自己做的板子,连接的时候报错:

    查过连接器,连官方的开发板EVM6657没问题;

    查晶振,有时钟;

    查电源,没有全面查,基本上是对的。。。

    请问楼主是怎么解决问题,还有没有其他思路?

  • 我遇到这个问题,后来解决了,是因为系统的供电功率不够。功率上去了,就解决了
