芯片为TMS320VC5509A,只是用MCBSP扩展了一个外部FLASH,但与仿真器接通的时候CCS每次试图连接都出现错误,提醒CPU初始化失败,通过检查发现JTAG口线路连接没有问题,电源电压正常,内核电压正常,复位脚正常,晶振有起振(不过连接的12M晶振但频率却是48M,尚未给DSP下载程序),
这样的话,问题会出现在什么地方呢?
我同时焊接了两块板子,都有问题,其中一块错误提醒如下:
Error connecting to the target:
Error 0x80000242/-1143
Fatal Error during: Memory, Initialization, OCS,
The memory at 0x000000BE continually indicated it was \'not ready\'
All memory operations currently in progress were aborted in order
to regain control of the processor.
This is considered a catastrophic event, but the debugger should
still be able to access memory and CPU registers.
System state has been altered. It is strongly advised
that the processor should be reset before resuming execution,
Board Name: C5509A XDS510 Emulator
Cpu Name: CPU_1
Abort: Close Code Composer Studio.
Retry: Try to connect to the target again.
Cancel: Remain disconnected from the target
Diagnostic: Run diagnostic utility.
令一块板子一直就不正常,
错误如下:
Error connecting to the target:
Error 0x80000242/-1146
Fatal Error during: Memory, Initialization, OCS,
Invalid data was scanned by the emulation controller.
Verify the board setup to make sure the scan chain is properly
defined.
If the setup is correct, then RESET EMULATOR. This will disconnect each
target from the emulator. The targets should then be power cycled
or hard reset followed by an emureset and reconnect to each target.
