| |
I'm running an ATCA7101 board. This board has two 16550 ports that get detected as ttyS4 and ttyS5.
With a much earlier kernel (2.6.14) the serial port base speed is correctly detected as 230400, which gives the desired 115200 when I specify that on the kernel commandline.
With 2.6.16 and 2.6.27 (not sure about the intervening kernels) the serial port base speed is detected as 921600, which means that I need to specify 460800 on the commandline to get a real speed of 115200 (as verified by an external terminal server).
Any ideas what could be causing this misdetection? I'm having lab issues right now so I can't track it down, but I'll have a go at it eventually.
Thanks,
Chris
