I have been unable to communicate to my GPS module using a terminal application using COM-1. I can open the other COM ports (2 and 3) but COM-1 behaves as if it is being used (cannot open COM port). I realize COM-1 is initialized by the bootloader but I do not think that it would stay initialized and in use even after CE boots. Maybe I am wrong? I do not have the TTL converter for my other COM ports but I know for certain my GPS module works perfectly with my PC using Putty. Any insight is appreciated!
COM 1 Not Working??
Also note I have my CE image built as a "Ship Build" meaning ALL debug strings and functions are disabled.
Hi, COM1 is working for me in WinCE I am using it to communicate with a program in the PC as the network driver seems to have issues. Unless some other program in WinCE has already opened it up you should not be getting the problem. COM2 and COM3 ofcourse are working too as I am using COM2 to communicate with another 3.3V serial device.
crmann, did you enable KITL on COM0 in the Options.H? Shanty, the network drivers have been fixed in the BPS on the wiki(as far as i know), see: http://code.google.com/p/friendlyarm/wiki/EnglishBSP Thanks, Errol
I checked options.h and KITL was disabled. I would think this would be the correct configuration? KITL is used for debug so I would think it would interfere with a device on COM1. I didn't have a whole lot of time to work on it this weekend (build + download is almost an hour!) and didn't try building an image with it enabled. After I re-read what KITL was for I assumed it was best to leave it disabled.
if you don't use main serial cable of mini2440,I should say to you that in COM1's Port of board Rx and Tx Pin is displaced(that means Tx is Rx and Rx is Tx)...
