Bad things happen when I try to use the firmware download tool from the NQC
environment to download an SREC file produced by either Web cross compilor.
After a long wait, during which the bar graph that tracks loading progress
lengthens, I get "Firmware download failed." Yet this same tool happily
downloads the standard lego firmware (firm0309.lgo). If I use NQC directly in
DOS via the -firmware option, things are worse: initially, I get "downloading
firmware" and a row of dots, but finally the RCX makes an ascending beep, and
I get "No reply from RCX". Then the RCX powers off, and I have to
remove/replace a battery to proceed. I am running LEGO version 1.5 on Windows
98. I tried to include the sample SREC file below, but lugnet cannot accept
binary posts. Can anyone help?

This may (or may not) account for your problem. Either way, the bug will be fixed next (...) (25 years ago, 30-Nov-99, to lugnet.robotics.rcx.legos)
