Occasional ContributorHow to correctly read data from FIFO on HPS and send it out through HPS Ethernet
Hi,
We only have two examples, but on old version so you can use them as references, unfortunately we do not have the latest version for this:

Occasional ContributorHello EBERLAZARE,
After the FIFO of the sending board, I used mSGDMA to first send the data into the HPS DDR, and then used the sendto function on the HPS side to send this data. After receiving the data on the HPS side of the receiving board, the data is sent to the HPS DDR through the mmap function. Next, I will study how to use PL330 DMA to write data from the HPS side to the HPS DDR.
Thank you again for your help. Please close this thread.
Best regard.
