AM6442: IO-Link Master Example Project - What is the order numbers for Breakout boards.

Part Number: AM6442
Other Parts Discussed in Thread: TMDS64DC01EVM, AM2431

Dear Ti support,

1)

Per software-dl.ti.com/.../page_quickstart.html

is the following required to evaluate IO-Link master.

Connect the Evaluation Board

  • Connect the IO-Link/Breakout Board TMDS64DC01EVM to the AM64x EVM board via J2 and J3.
  • Connect the AM64x EVM to a 12V power supply.
  • Connect the IO-Link/Breakout Board TMDS64DC01EVM to a 24V power supply.
  • Connect the evaluation board to the computer using two micro-USB cables going to the J26 UART
    (for IOLink SMI Communication) and J28 JTAG (for uploading and debugging) on the AM64x EVM board.

I have the SK-AM64 board and i can ran the demo and connect it to IOL_Master_GUI application. It is possible to evaluate IO-Link master on SK-AM64? Could you please share the link where the IO-Link/Breakout can be ordered. Is there any guide how to connect Breakout board to SK-AM64?

Second question is about uart.

Per https://software-dl.ti.com/mcu-plus-sdk/esd/AM64X/latest/exports/docs/api_guide_am64x/RELEASE_NOTES_08_00_00_PAGE.html is UART DMA not supported.

UART R5F, M4F YES Basic read/write, polling, interrupt mode, HW flow control not tested. DMA mode not supported

Does this affect also AM2431 part number? Is DMA from UART peripheral not possible at all? We plan to scale down to this part number in future. We will be running two tasks that communicate over uart. One is doing polling based transfers at >100 kbps baud rates and have to achieve real time response. Second one is communicating at >1 Mbps baud rates and is not so important thus we planed to offload it via dma and keep MCU free for polling.

Thank you.
