AWR1843AOPEVM: mmw Pin MUX doesn't match the schematic

user1213293

Part Number: AWR1843AOPEVM
Other Parts Discussed in Thread: AWR1843AOP, , AWR1843

Mmw files which are located in mmwave_sdk_03_05_00_04\packages\ti\demo\xwr18xx\mmw are AWR1843AOP out of box demo software.

The Pin MUX(MmwDemo_platformInit(MmwDemo_platformCfg *config)) doesn't match the AWR1843AOPEVM schematic

How does it work?

Thank you for your reply.

We can rebuild the out-of-box-demo without pinmux_xwr1843AOP.h. Everything are working fine.

We just don't understand how does mwDemo_platformInit(MmwDemo_platformCfg *config) work for AWR1843AOP with the wrong pinmux configuration.

Hi,

Sorry for the delay,

The values for the pinmux used in mwDemo_platformInit() are the same for both AWR1843 and AWR1843AOP. This is the reason why this function works for AWR1843AOP as well.

The reason why we need a new header file for AWR1843AOP is that the "C:\ti\mmwave_sdk_03_05_00_04\packages\ti\drivers\pinmux\include\pinmux_xwr18xx.h" defines include the "XWR18XX" name. But the PAD values are the sames.

thank you

Cesar
