You have to comment CONF_PROGRAM if you commented CONF_TM, but I am not sure if you still can download your program without CONF_PROGRAM. I don't think you can comment CONF_TM. Zhengrong ---...--- (...) (23 years ago, 7-Nov-01, to lugnet.robotics.rcx.legos)

Hi, Is the kernel size simply the size of the legos.srec file? I thought so initially, however my legos.srec file is 18800(or close to) and im pretty sure ive allocated more than than 19k using dynamic memory. Obviously this is more than 32k in (...)

The only concern that I would have with this kind of an implementation is that if you plan on changing your brick's LNP address, you have to remember what address it used to be while you're downloading a program. It's not a huge deal, but it's an (...) (23 years ago, 6-Nov-01, to lugnet.robotics.rcx.legos)

I think you actually want dll -r10 the -r flag specifies which RCX to download the specified program to. you need the 10 because it is read in as a hex address.

Addendum: It seems bad to put legOS under /usr/lib. Please get a fresh legOS.tar.z from legOS.sourceforge.net and install it in your user home directory. (for me, that means in /home/obi.
