i3c_edma_b2b_transfer_master
Overview
The example shows how to use i3c driver as slave to do board to board transfer with EDMA.
In this example, one i3c instance as slave and another i3c instance on the other board as master. Master first enters dynamic address cycle to assign address to the connected slave, after success, will use I3C SDR mode to transfer data, then receive data from the connected I3C slave and check the data consistency.
Running the demo
The following message shows in the terminal if the example runs successfully.
I3C board2board EDMA example – Master transfer. Master will send data : 0x 0 0x 1 0x 2 0x 3 0x 4 0x 5 0x 6 0x 7 0x 8 0x 9 0x a 0x b 0x c 0x d 0x e 0x f 0x10 0x11 0x12 0x13 0x14 0x15 0x16 0x17 0x18 0x19 0x1a 0x1b 0x1c 0x1d 0x1e 0x1f
I3C master do dynamic address assignment to the I3C slaves on bus. I3C master dynamic address assignment done.
Start to do I3C master transfer in I3C SDR mode.
I3C master wait for slave IBI event to notify the slave transmit size. I3C master received slave IBI event, data size 1, value 0x20.
I3C master transfer successful in I3C SDR mode.
Start to do I3C master transfer in I3C HDR mode. Receive sent data from slave : 0x 0 0x 1 0x 2 0x 3 0x 4 0x 5 0x 6 0x 7 0x 8 0x 9 0x a 0x b 0x c 0x d 0x e 0x f 0x10 0x11 0x12 0x13 0x14 0x15 0x16 0x17 0x18 0x19 0x1a 0x1b 0x1c 0x1d 0x1e 0x1f
I3C master transfer successful in I3C HDR mode.
