I think it was already suggested: you need to enable flow-control. Either
hardware if you've got the pins setup right on that port or software

Hi Michael,
I have tried with baudrate = 9600 and 19200, then it is working fine(i.e
getting data, no overruns). but i want to use high speed(115200). can u
please give any suggestion to over come this.

Raju,
I would expect data overruns causing lost characters if your CPU utilization is
high and your kernel
driver can't get back to servicing the UART IRQ fast enough. Your MCF523x part
appears to have
only a small FIFO buffer (a shift register and 3 receiver registers). So if

Raj,
Which ColdFire are you using?
Which serial interface are you seeing this with (UART/SPI/I2C/..)?

Still struggling with 2.6.38 kernel and memory allocation. We've been RTFMing
but still aren't able to run on 2.6.38. Any insight much appreciated.

I have a 4.7MB application that runs on the 2.6.26 kernel (Freescale BSP) and
am working to make it run on the 2.6.38 kernel released in the ColdFire BSP in
Feb 2012. I'm concerned about memory allocation as my first attempt to run on
the 38 kernel appears to be using 2^n memory allocation vs.
