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.
