Hello. I need some help with getting the serial ports working on a TWR-SER2. My system configuration is:
- 700-27166 REV A
- SCH-27166 REV C2
- 700-26185 REV B
- SCH-26185 REV D
I can communicate from the Kinetis board to a PC using printf and the BSP_DEFAULT_IO_CHANNEL, which happens to be ttyc:. This causes communication to go over the OSBDM/OSJTAG - CDC Serial port and works fine.
I have enabled BSPCFG_ENABLE_TTYA through TTYF in user_config.h and recompiled the BSP. I try to open a port and send a string using code like the following:
fh_ptr_a = (pointer)fopen("ttya:":, BSP_DEFAULT_IO_OPEN_MODE);
I am trying to see the result on my PC through the Serial-to-USB connection (UART 0)
No matter which port I choose (except for "ttyc:"), I do not get any communication to the PC. I have installed the driver on the PC side, and the connection shows up as a valid com port on the PC.
I have not modified any default jumpers on the TWR-SER2.
I have tried changing J19 on the TWR-K70F120M, and neither setting seems to make a difference.
I have a feeling that am missing some basic setting, or that there is an incompatibility that I am not aware of. Any help would be greatly appreciated. Thanks.
