Minicom works with u-boot. Search the archive of the mailing list for details.

Richard,

I'm using kermit+minicom+uboot fine all the time. you can try to configure minicom to call kermit directly. here is what i did: 1. install ckermit on a linux machine(on RH machines, you can find RPM for direct installation) 2. when you configure minicom by "minicom -s"(you have to be root), 2.1 go to 'File Transfer protocols",you will find two lines commands for kermit, replace the default "%l" by "%f", e.g. change /usr/bin/kermit -i -l %l -s to /usr/bin/kermit -i -l %f -b %b -s YUYNN, another line could be /usr/bin/kermit -i -l %f -b %b -r NDYNN 2.2 go to "Serial port setup" and configure your serial port and baudrate there. 2.3 go to "Modem and dialing", erase the strings after A,B,K, i.e. make these three lines empty 2.4. go to "save setup as dfl" 2.5. go to "exit from minicom" 3. make sure your serial port devices are 'rw' to non-root users 4. as a non-root user, run 'minicom' again, and boot up u-boot and get the u-boot prompt inside minicom 5. under u-boot, when you want to do a binary download, for example, you do something like: u-boot>loadb 1000000 ramdisk 115200 //now you can do Ctrl-A-Z, then press 'P' to choose the download baudate to 115200(if you're not using 115200 as your default baudrate), then do Ctrl-A-Z, and press "S", scroll down to 'kermit' and press on it, you will be presented a browser window to choose any file you want to download via kermit. 6. after the download, you do "imi 1000000" to check the integrity for the downloaded file.

this is the procedure we're using at motorola, and it works fine.
