UARTecho and USB_dev_serial example do not run on AM3359 IDK...

... because there's no connection from DSP UART0 to RS232 SUB-D-9 J12 on the bas board. I had to dig into the schematics to find out that R361 ff. are not inserted. The DSP pins are used as CAN instead. No hints in docs (User Guide, Getting started) or http://processors.wiki.ti.com/index.php/AM335x_Industrial_Automation_EVM_User_Guide#RS-232_Connectors. (Here UART5 at J12 ??)

Hardware for UART3 to RS232 J10 seems to be ok, but the uartEcho/uartEcho.c and platform/uart.c seem to be programmed for UART 0 only.

Any experiences how to change to UART 3? (Resoldering the board isn't an option, we need CAN too.)

To get the USB_dev_serial example compiled & run, I had to recompile the sub projects (platform, system, drivers etc.) that are build with incompatible floating point options (some with, some without). I removed the Display stuff in Usb_dev_serial.c, and I got the USB connection to the PC as virtual COM port. However, the example uses the same UART software fixed to UART 0...

The final goal is to have all the things run under SYS/BIOS, I think I've heard that there are efforts at TI. What's the state of the art?

  • There are two UARTecho examples, \sdk\examples\uartecho using SYS/BIOS is working fine with UART 3, the one not running is the OS-less sdk\starterware\build\armv7a\cgt_ccs\am335x\evmAM335x\uart (this SW is also used in the USB example). Seems I have to mix...
