Hi All,

I am porting Linux to a MIPS based development platform. The UART on the board provides a maximum baud rate of 115 kbps. But the download time for the kernel Image of about 4.3 MB is about 4 hours !!!!!.

Can someone help me address this problem ?.

Yes, I think there's something definitely wrong. I wonder if the download is even in progress... You're using windows and hyperterm? Try it on linux but just doing "cat > /dev/ttyS0", assuming you're using the first serial port to connect to the target. Yamon gives you feedback of the download progress by printing dots, when downloading over ethernet. I imagine it does the same when downloading over serial port, so if you are not seeing any progress feedback, then perhaps that's another indication that your download is not working.

And it is taking about 7 minutes to download the Kernel Image of 4.3 MB. Do you know some other Terminal Emulator that can support a higher baud rate ?. The UART of the target processor supports the max. baud rate of 406 kbps. So I can use the terminal emulator that supports for example, 406kbps, then my download time may be further reduced.

You may also want to experiment with compressed kernels.

PCs are typically limited to 115200 because of the clock generator they use for the UART. However you can buy add-on cards that can support up to the 1.5MBaud rate of the 16550. Your local computer store should carry one of these. They typically plugin to a PCI slot and you should be able to blast down the kernel image to your board. That is the best way to get the 406kbps your board supports. Also instead of an SREC image, you can tryout the LSI fast-load format. It is a base64 encoded image, that some firmware supports (pmon for example). A fast-load kernel image is around 1/2 the size of a SREC. I can get a kernel image of around 5MB to download in 3 minutes or so via 115200.
