(...) Unfortunately, the standard firmware does not expose the ability to iterate through the files in the file system. You can do that with the enhanced NBC/NXC firmware, but even then the information you can get about a file is just its name and (...) (17 years ago, 7-Mar-08, to lugnet.robotics.nxt)

(...) Thanks, John -- this agrees with what Dave found as well. Makes sense. (...) Thanks again. What would be really neat is a utility that can draw a memory map, showing what is stored where.

(...) According to the LEGO Mindstorms NXT Communication protocol.pdf that is part of the Bluetooth Developer Kit, your error code (89) means "No linear space". That means all the remaining space on your NXT is fragmented so there is not enough (...) (17 years ago, 6-Mar-08, to lugnet.robotics.nxt)

OK, for the archives: I got an answer from Dave Baum (author of nxtcom). He says that error #89 indicates memory fragmentation -- even though my NXT had plenty of free RAM in total, there was no single contiguous block big enough to hold the new (...)

To follow up my own post: I've since verified that I have 45K free on the NXT, and the file I'm installing is under 13K. I've also restarted both my Mac and my NXT, and still get that mysterious error 89. After more experimentation, it does appear (...) (17 years ago, 5-Mar-08, to lugnet.robotics.nxt)

I've been using the nxtcom utility to download NXC apps from my Mac. It was working fine just a few minutes ago, but all of a sudden (starting about 10 minutes ago) it's giving me a "NXT Error #89". I've searched the web and read the read-me, and (...) (17 years ago, 5-Mar-08, to lugnet.robotics.nxt)

I'm just getting started with bricxcc (and winxp on my mac), so I'm hoping there's something painfully obvious I'm missing. I've compiled and run a few simple nbc and nxc programs (mostly from John's book), but invaders.nbc isn't working for me. I (...)

(...) I emailed Karen with the solution to her problem. This can trip you up if you aren't careful. Drawing values to the screen can confuse you if you draw over the top of an existing number without clearing the screen first. John Hansen (17 years ago, 29-Feb-08, to lugnet.robotics.nxt)
