hello, plus some notes on tools
2003-11-20 by cerfinker
Hello guys, I am interested in the LPC210x series. I've got a dev board plus some samples, and have been doing a tiny bit of software development. Mostly I have been working on some linux tools to interface to the bootloader on the LPC chip. So now I've got some things to send commands to the bootloader (though you could already do that over minicom), but also to take files uuencode, packetize with checksum, and upload. If anyone is interested in these, or has a place to put the files up, let me know. My website is down right now since I forgot to pay the bill... So far I've been using the GNU tools + libc for ARM found at: http://www.emdebian.org/gcc.html These work fine as far as my limited experiments go, but the libc doesn't seem to work right off the bat, at least with printf. Anyone have an idea of how to get libc terminal I/O stuff working? Seems like you have to maybe write some functions to send and receive characters? I'm sure its a totally different situation, but in the libc which has been done for GNU tools on the AVR architecture, you can get a FILE type stream open if you pass single char in and out functions to the open call. I would be happy to write those functions, I just don't know what to do with them after that in order to make libc use them. I guess the libc at emdebian is set up to run on linux on ARM, but we want something to just run on the bare metal... Of course I can write my own putc, puts, etc., but it would be great to just use the library. Well, any ideas would be appreciated. Thanks, and I hope a good community develops for LPC! -Holly Gates
