PCA85073A i2c rtc driver need for S32G274 board

[vimalrajendran]

Hi ,

       iam currently working S32G274 board. my kernel verion 5.4.69 version. i need RTC driver for PCA85073A chip.

[bpe]

The kernel driver for PCA85073A RTC is defined in rtc-pcf85063.c. The respective configuration option is CONFIG_RTC_DRV_PCF85063. The driver is enabled in Automotive BSP kernel by default.

Hi ,

i tried but boot log  showing below mentioned error

2.984709] 001: rtc-pcf85063 0-0051: RTC chip is not present
[ 2.984794] 001: rtc-pcf85063: probe of 0-0051 failed with error -110

Are you working with an NXP development or reference board? If so, please mention it's exact part number and the version of the Automotive BSP you are working with.

Hi ,

       i am working with NXP S32g274a our custom development board. and BSP version 29.0.0

Suggestions:

1. Make sure the RTC responds to the access cycles on the I2C bus it is
connected to.

2. Make sure the connection between the RTC and the central chip is properly
reflected in the Device Tree

Hi ,

 This is my device tree for pca85073a. if you want any changes in dtsi. please point out your idea.

&i2c1 { 
status = "okay";
clock-frequency = <100000>; 
rtc@51 {
      compatible = "nxp,pca85073a";
      reg = <0x51>;
     nxp,no-battery;
};

};

Thanks
