AM2434: How to process 100 bytes of transfer from address A to address B infinitely with UDMA

太岡崎

Part Number: AM2434

Dear Sir

I am trying to implement the process of repeating 100 byte transfer from address A to address B infinitely with UDMA of AM2434.

Does UDMA of AM2434 have the function to realize it?

Is "Reload Enable" or "Reload Index" in TRM's "11.1.4.16 BCDMA --Block Copy Operation (TR Packet)" related?

thank you very much.

I have one additional question.

The description of Reload Count says "A teardown operation on the channel will cause the loop to be broken at the nearest iteration boundary.", But I didn't know how to teardown.

Should I set the TX_TEARDOWN bit of TRT_CTL as shown in "11.1.4.15 BCDMA --Block Copy Channel Teardown"?

Best regards

Hi,

This thread looks like a duplicate of another thread: https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1121821/am2434-how-to-know-the-reload-count-with-udma-block-copy/4166566#4166566

I'll close this thread since the other thread is answered.
