MCU-PLUS-SDK-AM273X: 双芯片级联硬件如何用LVDS采数

Part Number:MCU-PLUS-SDK-AM273X

自己按ti推荐的设计做的双芯片级联(AM273X + 2xAWR2243 EVM)硬件,仿真器用的这个XDS110 ,请问如何用LVDS采数;


 XDS110测试test connect ,出现错误是啥原因


Gary Lu:


澄清一下,您是在问如何将 XDS110 调试探针连接到您的硬件并使用调试器,或者如何使用 LVDS 高速串行接口?

您使用的是 TMDS273EVM 还是定制硬件?



我的目的是要双芯片级联(AM273X + 2xAWR2243 EVM)硬件采数,但按文档的描述LVDS采数需要用CCS DEBUG加载固件,接着我就购买了XDS110 调试探针,XDS110 test connect打印这些:

[Start: Texas Instruments XDS110 USB Debug Probe_0]

Execute the command:

%ccs_base%/common/uscif/dbgjtag -f %boarddatafile% -rv -o -S integrity

An error occurred while hard opening the controller.

This error is generated by TI's USCIF driver or utilities.

The value is '-267' (0xfffffef5).The title is 'SC_ERR_XDS110_TARGET_SUPPLY'.

The explanation is:The controller could not detect valid target supply. Check targetJTAG connection and/or connection setting specifying voltage level.

Gary Lu:

您能解释一下 XDS110 JTAG 连接的拓扑吗?您能提供XDS110连接的相关原理图信息吗?
