I am currently using EVAL-M3-302F with EVAL-M3-CM615PN for an application. I can properly control the motor using the MCE designer. But to be able to control the motor externally I want it to be done using the UART1 of the chip. I have read in another post on community that UART 1 can also be used for user application without going through the MCU core(A core).
I have followed all the necessary steps to configure UART1 for user application. I use the example script provided for both(buffer and fifio mode). But It failed to communicated with my external microcontroller. When I probe pin 64 & 63 of the IMC302A-64, the pins are at zero volt. Does this mean that UART1 is not active?
How can I do this properly ?

Hi @sudip_k ,
Sorry for the delay in response.
Yes, there are no dedicated pins for USER UART. Please use the A-Core ( MCU UART) for communication purpose.
Thanks,

Hi @sudip_k,
Please try configuring UART0 – USER UART and UART1 – MCE UART in the parameter.txt file
TX delay | 0 |
InterfaceConf0 | 113 |
InterfaceConf1 | 0 |
This enables user UART communication from UART 0 Pin 45 and Pin 46
Note: MCE Designer will not be accessible.
Can you please share the MCE Wizard Configuration File(.mc2) this will hep us to understand the issue better.
Thanks,
Krupashankar
