Part Number: AM5708

Hi,

Which one refers to pr1_uart0 of the ten uarts in this picture? I really can not understand this in the AM570x TRM Rev. H.

Hi,

None of these. These all are standard UARTs. PRU UART pins are listed in Table 4-24 of the AM570x Datasheet Rev. D (page 93).

HI Echo,

Can you give us some more information about how you'd like to use the PRU UART? Do you want to use it with Linux or RTOS? Do you want to control it from the PRU itself, or from the Cortex-A or DSP cores?

Thank you.

Hello Echo,

We have an example of the PRU controlling the UART within the ICSS in our Linux Processor SDK. Take a look at example-applications/pru-icss/examples/am335x/PRU_Hardware_UART. You can run that example on a beaglebone black, or any AM335x board.

PRU controlling the UART on AM57x should be similar, but there could be some differences.

Regards,

Nick
