hi, Finally i found the solution. This is the problem with device tree aliases of uart in am33xx.dtsi
i changed uart0 to uart1 in all the DTS files , then its working fine. previously i am loading the overlay with diffrent aliase name, because of this the driver is not able to map the uart pins correctly, Thanks and Regards, Varka Bhadram -- View this message in context: http://linux-kernel.2935.n7.nabble.com/OMAP-Serial-omap-ttyO2-problem-tp865529p865741.html Sent from the Linux Kernel mailing list archive at Nabble.com. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
