I need some help. I cannot seem to get the commapi installed right. Using JRE1.5.02, followed all the instructions copying everything where it needed to be, USB driver installed no problem, when Javaprog starts and i hit program to test it get the following:
Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: javax/com
m/CommPortIdentifier
Which I assume is bad. What can i be doing wrong

sadly, im not exactly sure why java does that. it means that the javacomm library isnt being seen. some computers it Just Works on, some it complains. i think if you muck with the classpath it will eventually work...we're supposed to have everything in python, which doesnt act so poorly but the software isnt done (its in the cvs repository)

what exactly is the procedure for commapi? I'm no java person so I followed their rather poor instructions (i tried this on two machines so far) but I think I may be missing something. Is it just a matter of copying the files to the respective folders and setting the CLASSPATH to go through that folder?

Re: Issues with getting bootloading software running
i've got the same problem. done everything they told but can't connect with my x0xb0x (#037 also running...but). i would like to try to upload the software via a microcontroller programmer....but is the "firmware.hex file", on the site, only a software update or is it also a bootloader update.Altitude wrote:I need some help.

if it's also a bootloader update, someone told me that i'm not be able to update via USB anymore.

Perhaps some of the stuff in this thread can serve as a guide? I had some trouble getting the bootloading to work and learned some valuable lessons on the way:
