I am trying to run firmdl.bat to put the leJOS firmware onto my RCX. Unfortunately, every time I run it, I get this error:
Error 2: Opening \\.\LEGOTOWER1
Open failed: open failure, errno = 2
I am running Windows 7 Home Premium 64 bit, with Java 7. I saw that you should only use Java 1.5, so I installed Java 1.5 and am specifically calling it instead of my normal Java installation. (I edited the batch file.) I have tried just about everything I can think of to fix this: switching out the RCX, switching from a 2.0 RCX to a 1.0 RCX, switching out the Tower, installing the drivers for both the first RIS and then RIS 2.0, all to no avail. I've also made sure to set all of my environmental variables in the command prompt. I feel like I'm doing some really obvious thing wrong!
Any help would be greatly appreciated.
Thanks in advance,
