OMAPL138 wince 6.0R3: how to change debug uart to normal uart?

Other Parts Discussed in Thread: OMAPL138

hi team,

my customer use wince6.0 R3 BSP on OMAPL138, now, customer want to change debug port (UART2) fuction, disable all debug information output on UART2, and use uart2 as normal serial port. we have try dummy the function in debug.c, though debug infomation did not output, but in wince we can not call for COM3(uart2), based on wince user guide,

NOTE: When a serial driver for UART 2 is included in an OS design the OAL debug output is disabled.

we have try to include UART2 serial driver included in OS design, the OAL debug out put is disabledm, but COM3 can not be used, we have try a free device manager, we did not find COM3 device.

would you please give me some guideline? thanks in advanced.

Hi Michael,

We built the BSP_WINCE_ARM9_01_10_00 BSP with UART2 enabled using the OMAPL138_AM8X_TI_DEFAULT project. Using this configuration the debug COM was disabled and we were able to open COM3 and send and receive data. We left the default baud rate for the test which was 9600.

We have uploaded the binaries that were used for testing.

Hi,

UART0: COM1, UART1: COM2, UART2: COM3, If you want to enable UART2 then you have to set the BSP_SERIAL3 environmental variable by selecting the UART2 catalog item for Catalog Items View. Then you have to perform a Rebuild Current BSP and subprojects option from Build Menu.

After the NK.bin is created you can open NK.bin from VS2005 and make sure that COM# registry entries are present under HKLM\Drivers\BuiltIn\ path

Hope this helps.

Thank You & Regards,

GSR
