Ok, I think I figured it out...I don't completely understand the logistics of makefiles, but I changed the following line in Makefile.common: Before: CFLAGS = -O2 -Wall After: CFLAGS += -O2 -Wall I suspect that a later assignment to CFLAGS was (...)

Hello, I recently bought the LEGO mindstorms Invention System kit and I am trying to get brickOS v0.2.6 working on my PC (Win98). I also have the USB tower. So far, I have found 4 bugs in the current script. I was able to fix 3 them or work around (...) (22 years ago, 13-Dec-02, to lugnet.robotics.rcx.legos)

The motor handler is only called once ever 2ms in the latest version of BrickOS (as opposed to every 1ms in earlier versions). This is a fairly recent change and it could be causing a "granularity" type problem with certain speed settings in your (...) (22 years ago, 12-Dec-02, to lugnet.robotics.rcx.legos)

|

I'm having a problem, and I hope someone can help me. I've been running winLegOS, and I've switched to the latest version of BrickOS. I created a way to control the motors, which will reliably speed them up, and slow them down by using different (...) (22 years ago, 12-Dec-02, to lugnet.robotics.rcx.legos)

| | sys_time (long post)
|
|
As I was poking around in the BrickOS kernel, it occurred to me that using the sys_time variable isn't entirely safe. Since sys_time is 32-bits and the processor can only read 16-bits at a time into a register, there is a period of time between the (...) (22 years ago, 12-Dec-02, to lugnet.robotics.rcx.legos)

(...) David, I was not sure how you tried to build the cross compiler but I know that Apple provides several gnu tools that work under Darwin.

Max, Aha! I did that and it got a lot further this time, but still failed. I'll have to wade through the log file to try and pinpoint where it went wrong as I don't want to post the whole 180k.

(...) You need to install the Cygwin gcc package. You need the normal Cygwin gcc to build the Cygwin->H8300 cross-compiler gcc. Max. (22 years ago, 9-Dec-02, to lugnet.robotics.rcx.legos)

John, It looks as if you don't have the cross compiler or it is is not in a known directory. Try searching your entire hard drive for h8300. That might bring something up. You should have either tired to build the cross compiler or downloaded it (...) (22 years ago, 9-Dec-02, to lugnet.robotics.rcx.legos)
