按照该链接输入如下命令:T4240 - JTAG chain does not contain any debuggable cores
(bin) 1 % config cc cwtap:192.168.1.200
(bin) 2 % ccs::config_chain testcore
(bin) 3 % jtag::lock
(bin) 4 % jtag::reset_tap 1
(bin) 5 % jtag::reset_tap 1
(bin) 5 % jtag::scan_in dr 256
(bin) 6 % jtag::unlock
(bin) 7 %
结果提示信息如下,请问可能是哪里的问题:
CodeWarrior Connection Server console display active (Tcl8.4.12 / Tk8.4.12)

Solved! Go to Solution.
It your board uses the MPC8280, use CodeWarrior 8.8 instead if CodeWarrior 10.5.
Use CodeWarrior 8.8 and CodeWarrior 8.8.6 patch. CodeWarrior 8.8.6 patch is needed for using CodeWarrior TAP.
This patch is available on the following page:

Test memory on your board using "Tools/Hardware_Diagnostics".

用 "Tools/Hardware_Diagnostics"打开了,错误内容详见.MPC8280 SDRAM 60x Bus配置问题
您好,SDRAM配置完后,对SDRAM的0地址,0x2000,地址,0x100000等地址范围内的地址单独一写一读,都是正确的。但是使用Codewarrior 下载程序提示0x2000地址数据和预期不一致?请问可能是哪里的原因?
这个问题已经解决了。非常感谢,有USB和以太网的参考程序吗?
Check your IMMR value.
Often incorrect IMMR value produces similar behavior.

您好,请问MPC8280和SDRAM的配置有什么快速的参考吗?我现在怎么配置都不对。
这里有一个和我同样的问题,但是不知道最后怎么解决的。https://community.nxp.com/thread/356408
但是目前的现象是 特殊寄存器
如果是IMMR配置错误的话,应该这些寄存器都不可修改吧。

这个问题解决了,但是遇到另一个问题了,你能帮忙看下吗?https://community.nxp.com/thread/516613
Test connection to your CodeWarrior TAP using the following commands in CCS window:
log v
source IDcode.tcl
See the following page:
