问题如图,我实际工程的芯片用的是TMS320VC5509A的型号,但是CCS8.0里面只有TMS320C5509A,少了一个V”,我不知道这有什么区别,因为我选这个一直连接不了,早先的时候可以连接,但是run总失败
Shine:
选c5509A可以的,都是c55x的内核。
之前可以连接,现在不能连接是由改动过硬件吗?报错信息是什么?

回复 Shine:
Error connecting to the target:
(Error -516 @ 0x0)
The user selected specific frequency failed the scan-path reliability test.
The utility or debugger requested the JTAG controller and cable,
that generate the JTAG clock, to provide a user selected fixed
frequency.The built-in scan-path reliability test has failed.
This indicates that the JTAG controller and its cable cannot
reliably communicate with the target system at that frequency.
(Emulation package 7.0.188.0)以上是报错的信息;
硬件没有改过,用CCS3.3和510仿真器是可以连接成功的,但是仿真会跑飞,可能是我程序有点问题。但是现在我用CCS8.0和XDS100V3就连接不上,出现这种问题
