DSP UART support in K2E processor

Other Parts Discussed in Thread: 66AK2E05

Hello,

The 66AK2E05 has 2 no of UART ports.

Can we use one of the UART port as a K2E DSP debug console?

Please clarify.

Regards

    Hi Tarang,

    The UART ports can be used as debug console.

    Hello Tsvetolin, 

    so, that means, we can provide two no. of UART ports on our board using 2 ports of K2E SoC. 

    Also we can access both UART at the same time - one of K2E DSP Debug console and other for ARM Debug console. 

    is my understanding correct? please confirm. 

    Thanks and Regards

    Tarang,

    Yes, your understanding is correct you can use two different UART instance as debug console from ARM and the DSP. If you use a single UART instance then there is a possiblity of resource conflict when both ARM and DSP access it. However when you use 2 different instances there is no conflict as the UART has independent configuration registers and resources associated with them.

    We generally recommend this kind of an approach when UART based logging is required both from the ARM and the DSP.

    Note that on the EVM however we have onnly one UART instance that has been brought out to connect to the serial console for logging so you may not be able to this on TI EVM platform but on custom hardware you can design the board to have 2 UARTs to log console messages from ARM And DSP.
