"I want to create simple tasks to send address and data from the master to the slave without any burst-length violations, making sure to include wstrb.
wstrb
When an AXI4 master and AXI3 slave are connected via an NoC bus and perform transactions, the AXI4 master is set with awburst = 1, awlen = 1, awsize = 2, and wdata is 64-bit. Meanwhile, the AXI3 slave is configured to receive inputs with awburst = 1, awlen = 1, awsize = 2, and wdata is fixed at 32-bit.
awburst = 1
awlen = 1
awsize = 2
wdata
I think that if the master sends a 64-bit transfer in one burst, and the slave receives it as two 32-bit transfers, there shouldn’t be any protocol issues. However, GPT suggests that the awlen of the AXI4 master and AXI3 slave must match to avoid burst-length violations. If I make awlen match, it will change the original behavior I intended.
awlen
In what cases does a burst-length violation occur?"
I mean ChatGPT.
BTW, If I send a 64bit data from AXI4 to axi3 32bit slave, first data recognized but second data doesn't. I have attached waveform. Would you please give me any idea for this issue?
sorry my waveform is very small, so I make a link. https://imgur.com/a/CfYaHdj
I sent a 64bits data 'hcafe_c8c8_a5a5_1f1f to 32bit data width slave. but slave only recognized a5a5_1f1f.
