Intel Arria 10 SoC - HPS Ethernet and FPGA

[RubenPadial]

Hello,

I need to receive some data with the HPS Ethernet with TCP/IP protocol, process them and share with the FPGA.

Is there any example or AN?

What are the steps to get a program to process the data in the SoC and share with the FPGA?

Thank you in advance.

Hi,

Kindly take note that they will be some slowness on the first reply due to the public holiday, we will get back to you as soon as possible.

Thanks

Hi,

Which one you are targeting the baremetal application or Linux or MicroC/OS II ?

Hello,

I'm working on Linux.

Hi, 

In linux you need to write the socket programming to build the TCP/IP application over ethernet for server or client on board. 

It is generic way of writing the linux TCP/IP app. For reference you can refer below link

https://www.geeksforgeeks.org/tcp-server-client-implementation-in-c/

For HPS & FPGA data transfer, please refer the below link. Same need to be implemented for Arria 10.

Hello @Jeet14,

Thank you for this information.

If I'm not wrong, the example you sent me about DMA is to manage data between HPS and FPGA memories once data is received by an Linux client application in the HPS. That's very useful but it will be very helpful if you could give more details about how to build/run the client app for the Arria 10 HPS.

Thank you in advance

https://www.geeksforgeeks.org/tcp-server-client-implementation-in-c/

For your reference, you can follow steps as hello world application.

Add yocto application and compile using meta-bake.py script 

  

$cd meta-intel-fpga-refdes/ 

$mkdir recipe-example 

$mkdir helloworld 

$cd helloworld 

Add the .c & .h files and create the helloworld.bb file in helloworld directory. Snapshot from the helloworld.bb file.

$nano helloworld.bb

LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/BSD-3-Clause;md5=550794465ba0ec5312d6919e203a55f9" 

  

  

inherit systemd pkgconfig 

  

SRC_URI = "file://helloworld.c" 

  

S = "${WORKDIR}" 

  

do_compile() { 

        ${CC} ${CFLAGS} ${LDFLAGS} helloworld.c -o helloworld 

} 

  

do_install() { 

        install -d ${D}${bindir} 

        install -m 0755 helloworld ${D}${bindir} 

}

Hello @Jeet14 

Thanks for the information.

Is EDS needed to create the TCP/IP client application or the application to transfer data from HPS to FPGA memory?

Is it necessary to create a linux yocto with the custom applications/recipes?

Is there any detailed guide?

[Jeet14]

Hi,

You need to use the EDS for creating the preloader or uboot.

For creating the linux userspace application, you need to use the host linux machine where you need to use the intel cross compiler or yocto application method.

please refer the create your project with timer example for arria 10. ethernet TCP/IP not availble but you are try the previous links and follow the same steps.
