Hi TI team,
We have a pinmux and CAN-FD peripheral question about AWR1843AoP. Our silicon revision is ES2.0. I am assuming this silicon revision is identical to the released revision on the official AWR1843AoP page.
Our question is related to this E2E post: https://e2e.ti.com/support/sensors/f/sensors-forum/978845/iwr6843aop-incomplete-documentation-for-mcan-controllers
Here's what we know:
1. We are using AWR1843AoP ES2.0 (ALP180A package).
2. We are referencing this datasheet: https://www.ti.com/lit/ds/symlink/awr1843aop.pdf
3. Our custom hardware connects CAN-FD TX/RX to balls B4/A4 per datasheet spec in table 6-1 page 10.
4. We do not see any activity on these pins when we configure the pin mux for CAN-FD operation on these pins. GPIO works fine on these 2 pins.
5. The linked E2E post seems to imply there is an error in the IWR datasheet and these pins A4/B4 cannot be used for CAN-FD
6. The pin mux tool ( https://dev.ti.com/pinmux/ ) lacks support for AWR18XXAoP
Can you clarify which pins in table 6-4 are valid for CAN-FD operation?
Will we be able to use CAN-FD on pins A4/B4 or will hardware changes be required?
Thanks.
