YAMON only prints '.' feedback for ethernet download, unless you modified it. Download a copy of TeraTerm and use that instead of Hyperterminal. Then you can use the "Send File" command under File pulldown. This gives you feedback showing how many bytes have been transferred. I was able to load a 6.4MB linux srec image in 27 minutes on my Malta 4Kc board with baud rate set to 38.4K. Using TFTP over ethernet it takes 17 seconds. Another alternative is to consider buying an EJTAG probe and loading thru that. The probes will probably load something this size within 1-4 minutes. This is assuming you have EJTAG interface available. But I wouldn't buy a probe just to download code. ;-) -earlm -----Original Message----- From: Pete Popov [mailto:ppopov@mvista.com] Sent: Friday, September 26, 2003 9:09 AM To: Adeel Malik Cc: linux-mips@linux-mips.org Subject: RE: How to increase download speed for UART On Fri, 2003-09-26 at 08:41, Adeel Malik wrote: > Yes this is an Motorola's S-Record File.

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 <srec file name> > /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.
