Hi,
I am using my uarts (ttyO1, ttyO2, ttyO0, ttyUSB1) using in my am3354 platform and customized drivers in sdk6 Linux 3.2 is working good. When I am using the same uarts in Linux 3.12 sdk7 is giving many issues. Some times the ports are detecting suddenly and stop, some times if I access one uart and the same time if I am using ttyUSB is giving an issue. Simultaneous data is not coming in all uarts. Could u send me the drivers enable logic for serial ports. In Linux 3.2 I am using only 'omap serial port' and DMA disabled.
Please share the feedback why it is behaving in Linux 3.12. Any patches or modifications required to enable multiple uarts in my am3354.
Regards,
Anil
