AWR1843AOP: PinMux config for AWR1843AOP

Hello Jack,

Could you let me know which version of syscfg  the customer is using?

Regards,
Saswat Kumar

Hi Saswat

We tested via cloud Version. Could not get a chance to test with Desktop version.

It will be the latest version of cloude since we're unable to switch version by me. 

If AWR1843AOP device can not be supported via Sysconfig, 

Please let us know how to configure thoes pins. We need alternative solutions even without sysconfig tool.

Thanks.

Regards,

Hello Jack,

Its not possible to add the AWR1843 AOP in the syscfg as it supports only the AWR18XX.

Also the configuration looks fine, when you say not functional, what is not working? Is it giving an error?

Hi Saswat 

Thanks for our kind answer.

BTW, 

According to the customer, the waveform is not outputting even though the pin is currently set.
This means that no communication data is output or received.
For the other pins, the data waveform can be observed when CAN FD Message is sent, and interrupts are generated when data is received.
However, A4 and B4 pins do not experience data output and reception interrupts.

In the E2e thread above, it is said that A4 and B4 pins cannot be used for CAN-FD, so please check the availability of CAN-FD.

Thanks.

Hello Jack,

So the software is running fine, but you are not seeing any output in the hardware pin?

Yes, Nothing is shown

Hello Jack,

In the header file: C:\ti\mmwave_sdk_03_06_00_00-LTS\packages\ti\drivers\pinmux\include\pinmux_xwr18xx.h
There are other pins that can be used for CANFD..
Can the customer try the pins ad see which one is currently functional for them.

Saswat Kumar

Hi Saswat Kumar

Thanks for your kind follow up.

According to customer's test result, 

CAN_FD PIN is functional with F2, D1 and T3 and U8. All the pins are functional  OK for CAN-FD.

However B4 and A4 are not working for CAN-FD. 

Please check if B4 and A4 able to support CAN-FD function. 

Thanks.

Jack

Hello Jack,

I can check this with the team, but as they can use the other PINs, please tell them to use those so they can be unblocked.
