Hello,

        Did anyone tell me how may i get pinfunc.h for ls1043a. I want to use "Pin function ID" (<mux_reg   conf_reg   input_reg   mux_mode   input_val>) in my dtsi files.

Thanks in advance.

There is no "pinfunc.h" for the LS1043A.

Pins with multiplexed functions are configured only once - during power-on initialization of the processor according to the RCW settings.

Refer to the QorIQ LS1043A Reference Manual, 3.4 Signal multiplexing details.

Hi ufedor,

Thanks for the reply. I have already used RCW settings for signal multiplexing and these settings does not allow individual pin multiplexing (support pin group multiplexing).

For example, it is not possible to configure SPI_CS_B[1] as GPIO2[1] {RCW[SPI_BASE] = 10} if i am using SPI_CS_B[0] as Chip select {RCW[SPI_BASE] = 00} as setting option is same for both configurations.

Let me know if there is any alternative for muxing other than using RCW.

 

Thank you.
