TDA4VM: RTC MCP79410的调试

Part Number: TDA4VM

您好,我现在使用的SDK是Processor SDK Linux for TDA4VM 09_01_00.

按照[FAQ] CCS/TDA4VM/J721e/J7200: How to enable RTC on Jacinto TDA4x EVM? - Processors forum - Processors - TI E2E support forums此帖子进行了相应的配置,

断电上电后查看/dev/rtc*,只有/dev/rtc 和 /dev/rtc0,通过dmesg | grep rtc,
[ 1.761701] tps6594-rtc tps6594-rtc.4.auto: registered as rtc0

[    1.767663] tps6594-rtc tps6594-rtc.4.auto: hctosys: unable to read the hardware clock

并没有看到ds1307(mcp79410)的RTC。

请问除了上述帖子中的配置外还有什么需要配置的吗?如何确认MCP79410是否正常工作?

感谢!
