IWR1843BOOST: Bring out GPIO28 on pin P4 fails in SRR-MSS

Part Number: IWR1843BOOST
Other Parts Discussed in Thread: SYSCONFIG

Hello,

as I need one more GPIO I redefined P4 (SYNC_OUT) to GPIO28 via sysconfig.

Includes were added to mss_main.c

#include "pin_mux_config.h"
#include <ti/drivers/pinmux/pinmux.h>

in routine SRR_MSS_mssProcessDataPathTask I added

Pinmux_Set_OverrideCtrl(SOC_XWR18XX_PINP4_PADBB, PINMUX_OUTEN_RETAIN_HW_CTRL, PINMUX_INPEN_RETAIN_HW_CTRL);
Pinmux_Set_FuncSel(SOC_XWR18XX_PINP4_PADBB,SOC_XWR18XX_PINP4_PADBB_GPIO_28);

pin_mux_config.h and the sysconfig file were added to the project directory.

During compilation this failed:

"../mss_main.c", line 741: error #20: identifier "SOC_XWR18XX_PINP4_PADBB" is undefined
"../mss_main.c", line 742: error #20: identifier "SOC_XWR18XX_PINP4_PADBB_GPIO_28" is undefined

Could you please tell me what went wrong here?

Thanks a lot!

The provided SRR demo is based on the 1642, are you able to compile the demo for 1843? If so, instead of using sysconfig, could you try hard coding the pinmux commands into it?

Christoph,

Can you please let us know about the origin of the SRR code?

Thank you

In case you are using Automotive Toolbox 3.3, (the SRR demo in this release uses mmwave SDK 3.5) make sure following header file is included:

C:\ti\mmwave_sdk_03_05_00_04\packages\ti\drivers\pinmux\include\pinmux_xwr18xx.h

Thank you

Hello all,

the combination of hardcoding and adding the pinmux_xwr18xx.h header file did the job!

The automatic sysconfig tool did not yield anything which compiled without the error.

By the way: The demo SRR for the 1642 is what I started with, though it is modified a lot meanwhile.

THANKS!

Christoph
