求助：DSP28035的jtag接口怎么接？
第一次用这个片子，参考了网上的原理图我的jtag接口：
ZLg的
另一个的
到底怎么接呢？有用过的前辈指教 一下！ EMU0/1最好上下拉到固定电平，这样不至于板子挑仿真器，其他jtag信号引脚上下拉不是必要，不过你可以考虑保留那些上下拉电阻位置，zlg做开发板的，他给的这个电路肯定可以用。 daFish 发表于 2015-4-13 14:45

ZLG这个5脚 接的地啊
我使用的jtag接口电路
本帖最后由 wukangkang 于 2015-4-13 16:19 编辑我使用的jtag接口电路 2803x系列的DSP没有EMU0和EMU1引脚的，但是我还是建议你做成与F280x及283xx相同的标准接口。 jinyi7016 发表于 2015-4-13 15:29

没细看，5脚应该接系统IO VCC才合理。 年代太久了，我之前做的板图找不到了，我没有纠结过这个问题，因为我参考的 Seed 和 Ti 官方的图，都是一致的。
楼主百度不到官方的图，可以去 Ti 官网，找到这个芯片，上边应该有个类似开发板的链接，里面可以免注册下载他的图。
如果没 2803x 的，可以参考 28335 的，这个有。 alcohol 发表于 2015-4-13 22:54

V2连不上啊，、
Error connecting to the target:
(Error -1170 @ 0x0)
Unable to access the DAP. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). 本帖最后由 jinyi7016 于 2015-4-16 17:45 编辑
