Thank you for your reply!

In the past a few days, I have been debugging the system in Cyclone 10.

I did the following things:

1) In Platform Designer, I create a new IP whose name BF5V. Please see the following picture.

2) the interface of my IP is AXI4Lite.

3) I convert Avalon to AXI4Lite. please see the picture below.

4) in C code, I try to control ADC and etc, and I can control them successfully. however, If I use the following C code to write Avalon bus, the data in S_AXI_AWDATA is not as expected. For example, I write 0x55AA, 0x33, 0x0001, 0x4000 to the bus, but the data on S_AXI_AWDATA is 0x55AA, 0x33, 0x4000. The data 0x0001 is missing.

Is there any doc about how to convert Avalon to AXI4Lite?
