Hi all, Iam trying to read the data from uart( EVM board) to which a receiver is connected. Whenever i tried to read the data it says that invalid arguement. But the samething works fine when i connect the receiver (through UART) to My pc. I tried with /dev/ttys1,2 but the result is same on EVM.
On pc i tried with /dev/ttyS0 which has worked fine. Could any one help me to solve this problem.
