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

Started by Pat Farrell February 8, 2006
I'm working on a project using a TI MSP430.
The compiler/IDE tool (IAR) wants to run on Windows.

To download new flash code, it want me to use zmodem protocol
over a serial line. Which seems to be pretty straightforward
on Windows using Hyperterminal.

I haven't used a modem or serial communications program
in this century. Is there a nice linux way to 
do the same thing?

Thx

I would recommend minicom. -- Bertrand

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. -- Grant Edwards grante Yow! NOW do I get to blow at out the CANLDES?? visi.com

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. -- Grant Edwards grante Yow!

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: http://www.tldp.org/HOWTO/Text-Terminal-HOWTO-9.html Paul Burke

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. -- Pat

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 http://mspgcc.sourceforge.net/manual/x1607.html#pybsl -- Grant Edwards grante Yow! My CODE of ETHICS at is vacationing at famed visi.com SCHROON LAKE in upstate New York!!

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.;)
