各位工程师好!
我们参考appro的dm368解决方案量产了一批板子,需要进行烧写。我们使用sd卡进行烧写的时候,发现“nand erase”操作出现大量 “Timeout! FAILED! ”错误。所以我们又尝试使用ccs烧写的方式进行测试,但是发现使用ccs以及xds560连接板子时报错如下:
------------------------------------------------------------------------
Error connecting to the target:
Error 0x80002240/-233
Fatal Error during: Initialization, OCS, Control,
This error was generated by TI's USCIF driver.
SC_ERR_PATH_BROKEN <-233>
The JTAG IR and DR scan-paths cannot circulate bits, they may be broken.
An attempt to scan the JTAG scan-path has failed.
The target's JTAG scan-path appears to be broken
with a stuck-at-ones or stuck-at-zero fault.
Board Name: DM6446 XDS560 Emulator
Cpu Name: ICEPICK_C_0
Abort: Close Code Composer Studio.
Retry: Try to connect to the target again.
Cancel: Remain disconnected from the target
Diagnostic: Run diagnostic utility.

想请教各位大牛:
1.-233报错一般是出于什么样的故障?
2.量产板子的烧写只使用sd卡(不使用ccs做初始化)是否正确?
PS:我们使用原始的开发板做测试,ccs和仿真器是可以正常连接板子的,sd卡也可以正常完成烧写。
十分感谢!!!
