I was all set to get going with my leopardboard 365 via minicom and to my suprise what I thought was a parallel port is actually a VGA output port on my host computer!! I dug up a mini USB cable and hooked the leopardboard to my computer but I have no idea how to communicate with the leopardboard. I already have the SDK installed and compiled on my host computer. Can anyone tell me how to communicate with the leopardboard via USB?
Ooh Ooh, I just went through this last night.
on the SDK setup communications as Serial.
and hook up a USB to serial adapter.
I ordered a 2.5mm cable open ended from Digikey and soldered the wired to a db9 connector and connected that to the Serial adapter.
now you can communicate with the board.
When I was ready to flash the board (4MB file) I hit a stumbling block. the "Make Install" does not realize that laptops don't have conventional serial ports. we have to use USB adapters.
What I did (and it worked) was look into the U-Boot/make.conf file when I was reading throught I found that it calls for another file /bsp/mach/bspconfig so I opened that one and found that there is a line:
the tty0 refers to serial port which my laptop does not have.
What I did was change the tty0 >>>>to>>>>ttyUSB0
so the line now looks like this:
I had tried to comment out the original line and add my new line in there but I'm not sure if # comments out stuff.
It would not work until I deleted the original line and just left my line in there.
hope this helps.
As vlcp pointed out you will need a usb to serial adapter (something like this www.coolgear.com/.../76528877.jpg). But, you can set your serial device directly from the configuration menu (make config):
1. Go to Installer Configuration -> Communication method with the target board -> Serial port
2. Installer Configuration -> Serial port for target communication -> /dev/ttyUSB0 (depends on where your adapter is registered)3. Change your settings in minicom. Execute 'minicom -s' go to Serial Port Setup and change your device (option A)
