I use 0.2.5 in windows (djgpp), and can't get by without using the slow download option (-s). If you have lighting problems, perhaps flipping the little switch on the IR tower will help. When I download stuff at school, it helps to have it set to (...) (23 years ago, 8-Aug-01, to lugnet.robotics.rcx.legos)

(...) I am using 0.2.4 under windoz and have had similar problems. I found that I must use the slow download option (-s) for the firmware to load properly. regards (23 years ago, 7-Aug-01, to lugnet.robotics.rcx.legos)

(...) Hi, i use 0.2.5 under Cygwin and sometimes i experience the same problem. I dont think its a problem with the legOS 0.2.4 distribution. The problem often occurs if its too dark or too bright in your room. It also happens if sender and receiver (...) (23 years ago, 7-Aug-01, to lugnet.robotics.rcx.legos)

Maybe have a light near the tower that starts flashing when it (...) (23 years ago, 4-Aug-01, to lugnet.robotics.rcx.legos)

(...) Hmmm, yes, you are right. In fact it woudn't make sense. My actual robot uses a little neural net and if battery goes low, the actual data will be sent to the PC to be saved.

So in the original firmware, the system is shut down if ultra-low battery is detected. If we don't want tot do that, we could change the ">" in the 2nd compare to a "<" to get some hysteresis. Or would it be usefull to stop legOS and do a shut-down (...) (23 years ago, 29-Jul-01, to lugnet.robotics.rcx.legos)
