Connection Problems - No start signal detected - forcing start
Hello,
I am trying to connect my printer to the host and am having connection issues.
The baud rate in the firmware and RH is set to 115200. I have tried the baud rate in device manager at 9600 and 115200 with no difference between them. Just to be sure I tried every other baud rate to no avail.
I am on PC running Windows 7 but the same problems were observed on my mac.
Any advice would be appreciated please

Make sure you have selected right communication protocol - repetier on marlin will not work. Autodetect should work at start, but always check log window with such problems as well.
Try 250000 baud as well as that is often used and e.g. repetier-firmware will take baudrate from first upload until you change EEPROM_MODE in configuration.h.
If printer has a display you should see it resetting printer on connection (with some boards not doing this).
I have tried 250000 (and all the values) and the same symptoms are replicated. Unfortunately the printer does not have a display,.
If baudrate is 115200 you can also use arduino serial console to connect. Then you can send simple commands without checksums like M115 just to see it communicates and sends some data. You will also see if you are using the right port. For non ascii baud rates you might need a serial terminal software to do the same test.
Any further advice?
'DIO94_PORT' was not declared in this scope
means you tried to use pin 94 but the board used/set in boards does not have that pin. Make sure you have set the right board in Arduino AND configuration.h and use only pins available for the board in configuration. Without infos I can not say which of these is wrong, but I'm sure you will figure out.
the firmware now compiles and uploads but after the cpu reset the computer stops recognizing the device as a bossa com port
but my hal.h has these:
Am I correct that the configuration.h should have #define RFSERIAL Serial instead?
After connecting hit reset and see if a "start" line appears in console. Also M115 should report a lot of info.
