Hi Titus,
Thank you for reply,
Sorry being late,
Busybox hwclock doesnt support "debug" option. :(
I have enabled "Debug support for SPI drivers" in kernel menuconfig.
I will try to probe the SPI clock during read.
Meanwhile, there is internal RTC configuration in am33xx.dtsi file,
Should it be explicitly disbaled by adding
status="disabled"
Thank you,
Regards,
Ankur
