TMS320C6747: CSL function

user5075695

Part Number: TMS320C6747

Hello,

I am writing programs in CSL, because I see no CSL example about PSC and pin multiplexing settings, I have no relevant settings in their own procedures, in the view of the value of the register, Found that the corresponding bit really set up. (I use C6747, UART interrupt receive data. Pdk_omapl137_1_0_1 \ package \ TI \ CSL)

What I want to know is:

1. PSC and pin multiplexing are not set in the CSL? If you need to set, I did not find the function of the pin multiplexing settings

2.If I want to set up the PLLC, can I use functions?I also did not find the relevant function in the CSL.

3.Why some folders only header files without source files. like \pdk_omapl137_1_0_1\packages\ti\csl\src\ip\pllc

I've forwarded your query to the software experts. Their feedback should be posted here.

All the functionality that you require can be found in the board library in pdk_omapl137_1_0_1\packages\ti\board\src\evmOMAPL137. Please check the source to see the Board_init and corresponding experience.

Hope this helps.

thank you for your reply，
I also want to know why I did not set the relevant Pin multiplexing and PSC in the program but the program is normal?（I use UART0）

Have you checked the default MUX mode in the configuration register for UART0 and the PSC register setting for UART0? If the mux mode is set correctly coming out of reset and the PSC register power up UART0 then you don`t explicitly need to change MUX mode.

If however, the reset state is not UART0 pin function and PSC is not power on then I suspect there is a API call to either board library or board support package that is configuring this setting and you will need to locate this call in the code.

If you are using Processor SDK RTOS for this device then this setup is in the board library in an API called Board_init(boardCfg);

Hope this helps.

Rahul
