BB-I2C2-RTC-DSX.dtbo not functioning with 5.10.168-X kernel #231

rbed23 · 2023-11-23T19:31:08Z

I have tried unsuccessfully to setup/run the DS1307 overlay on either kernels:

5.10.168-bone-rt-r71
5.10.168-ti-rt-72 (desired, bc incorporates the reset-gpios, reset-assert-us, reset-deassert-us for PCB RevC.3 ETH PHY fix)

It does run successfully with the following:

5.4.161-bone-rt-r63

also - just noticed the README on the beagleboard bb.org-overlays (git) states 'supported to 5.4.X'

🙄 shame on me -

RobertCNelson · 2023-11-23T20:26:53Z

The issue, this reference changed... rtc1 = "/ocp/rtc@44e3e000";

RobertCNelson · 2023-11-23T20:28:55Z

On Mobile so I can't check everything.. here is with 5.10.x https://git.beagleboard.org/beagleboard/BeagleBoard-DeviceTrees/-/blob/v5.10.x-ti-unified/src/arm/overlays/BB-I2C1-RTC-DS3231.dts?ref_type=heads#L41 we've moved to kernel specific as there is to much churn between releases

rbed23 · 2023-11-24T19:13:41Z

@RobertCNelson thanks for pointing that out -

Referencing the git line L41 above + the /lib/firmware/BB-I2C2-RTC-DS1307 file I copied earlier, I made the following modification and it is now working on my BBB 5.10.168-ti-rt-r72
