I am trying to transmit Ethernet frame on LS1021A TWR board using RGMII mode.
I followed the initialization process mentioned in the datasheet.
I have created buffer descriptors array (txbd). "bufPtr" points to a data buffer.
I have loaded address of "txbd" in TBASEH and TBASE0 registers and also in TBDBPH.
In TQUEUE register, I have enabled the Queue 0.
And for transmission, I set READY, INTERRUPT (and also, LAST) flag. I was waiting for DMA to read this Buffer, Transmit the data and clear the flag. But nothing happened.
Am I missing something?
