Hi All,
We are trying to enable UART1 and UART2 in DM6467 EVM. We are using
combined kernel tree which has DM355, Davinci and DavinciHD.
What all changes do we need to do in kernel files for using UART1 and UART2?
We found that this kernel already contains the support for all the
UART'S. So we just enable the number of UART in make menuconfig from 1
to 2 and transmit data. While performing loop back of data we are
getting following error.
"8250.c: Too much work for irq41."
Commands we use to perform loopback operation of UART1 are:
"cat /dev/tts/1"
"echo a5 > /dev/tts/1"
Also one surprising thing is that type detected for both UART's is
different, detected chips are as follows:
UART0: ST16654
UART1: ST16650v2
Is this detected chip proper?
Regards,
Deepika
