Using NetDuo MMC,  Connex 400, and a COnsole-ST card, I have flashed Gumstix .jffs2 filesystem image over serial successfully. And hitting any key gets me into Gum prompt is ok, but I'd like to flash over Ethernet instead as i have a need to do flashing remotely. I seem to want to use Putty to flash, but when i cycle power to the gumstix then hit the space bar to gain access to the Gum prompt, I lose  connection to Putty. So my Question is, is there any different gumstix cards, or process, that will allow me to flash a filesystem image from a remote location?  I need to do this over ethernet and as the serial is not an
option from remote location.thanks for your help.
