How can I upload the same program again to the RCX?
Should I always use lejosfirmdl first to delete the existing program first?
For example, I made a program hello.
So, I did lejos hello.
Then, I found some bugs and I recompiled it.
Then when I do lejos hello again and I'm getting error
Error 21: write
After I do lejosfirmdl, "lejos hello" works.
Is this the only way?
