Ticket Name: RTOS/TDA2EXEVM: uart2 no work

Query Text:
Part Number: TDA2EXEVM Other Parts Discussed in Thread: TDA2 Tool/software: TI-RTOS Hi Expert, I'm running PROCESSOR SDK VISION v03.04.00 rtos on tda2eg. TDA2 EVM and custom board both have. I modify and run CSL uart test present here: PROCESSOR_SDK_VISION_03_04_00_00\ti_components\drivers\pdk_01_10_00_08\packages\ti\csl\example\uart\uart_test I call UARTConfigInit() to initial UART2 engine after pin mux setting finish. but system get stuck problem when I call UARTConfigInit() API. Could you please give me some advise? Thanks in advance. attach is source file. 1832.main.c /*

Responses:
Hi, How are you running this binary? This is a standalone example that should be run using CCS. You should make sure that you are not booting Vision SDK when you try to run this binary. Also you can't run UART test for UART2 on the EVM as there is no connection for UART2. Regards, Rishabh

Hi, command window > gmake csl_uart_test_app BOARD=tda2ex-evm CORE=ipu1_0 Refer "Load using CCS" in VisionSDK_UserGuide_TDA2Ex.pdf to load and run csl_uart_test_app_ipu1_0_release.xem4 Tested in TDA2 EVM and custom board. It is normal to only test uart1 printing, but after adding UARTConfigInit() to initial UART2, uart1 is nothing print out. So guess the initial UART2 has a problem. Thanks in advance.

Hi, As I specified previously you cannot use UART2 for communication as there is no connection between UART2 pins and FTDI chip. On custom board you have to check the schematics and find out if there is a route available for UART2. You also need to set the pin mux, IO expanders, etc depending on board schematics. Regards, Rishabh

Hi, On custom board previously used linux to confirm that uart2 is working. There is a route available for UART2. --------------------------------------------------------------------------------------------- As I specified previously: It is normal to only test uart1 printing, but after adding UARTConfigInit() to initial UART2, uart1 is nothing print out. Tracking with CCS will stop at UARTConfigInit() to UART2. Why does UARTConfigInit() to UART2 the operation to stop? Thanks in advance.

Hi, UARTConfigInit() API modifies UART2 registers. Have you enabled UART2 in PRCM? If UART2 is not enable and you try to access the registers you will see a crash. Regards, Rishabh
