OT a little: Linux program to talk to serial port for downloading firmware?

I would recommend minicom.

It may seem to be straightforward, but Hyperterminal sucks so badly that things which seem to be straightforward usually aren't.

Kermit. If you have sz/sx installed, Kermit knows how to invoke it to send files.

Or you can just invoke sz from the command line or a shell script.

If you need a good windows terminal program, try teraterm.

Yup, that's what I was trying to remember. I avoid windows as much as possible, but on occasion in the past have had to do terminal stuff on Windows. Teraterm was always the terminal program that was recommended by the people who suffered windows for a living.

I've never understood this. The version shipped with Windows 2000 and XP is particularly heinous; under Windows 95/98 it mostly worked.

The normal MSP430 boot loader doesn't use zmodem, so I assume this is a loader that is part of the application. There are various Linux terminal emulators available, XTerm, eterm, rxvt, xvt among them. Look here:

Didn't know that. Its an Ember ZigBee board, The loader is not part of my application, may be part of the Ember stack.

I'm trying minicom. using an Xterminal is the wrong direction, It works great to let me enter shell commands on my linux box. I want to send characters out /dev/tty0

It seems that no one talks boring old serial RS232 anymore everyone assumes you have Ethernet and use TCP/IP for everything. Or they implement PPP for you.

Eh? The '430 has a built-in serial bootloader, and it doesn't use Z-Modem. Are you talking to some sort of ROM-monitor?

Unless you're talking to a ROM-monitor program on the 430, you could just use an MSP430 downloader utilities that runs on Linux

Minicom will proably work. I prever kermit. For Z-modem support, both depend on the command line "sz/rz" command line programs from the lrzsz package (at least that's the package name on Gentoo).

There are a few of us left.;)

Has anyone found a similar way to program the MC9s08?

Thanks.

Well, the '430 is embedded in an Ember dev kit. You actually talk to its "rabbit" processor. Plus, I'm a newbie at this embedded stuff.

Thanks for the link, there is tons of good information there.

There is a Linux flavor of the Professional-YAM comms program, with an integrated ZMODEM.

Industrial ZMODEM(Tm) is used in a number of embedded applications which are not well suited to the 1986 programs.

Try gtkterm. I use it for downloading code to an 8051 SBC.
