- BK 12:52 PM FPGA Development: RE: MitySOM-5csx custom board PL fabric ethernet access
- Hi,
Actually that timing issues were resolved and ping performance also well as of now without packet loss. And now I am working fine with RGMII splitter connected to the HPS EMAC of latency 2 microseconds in my setup, I want to under...

- TI 03:39 PM Software Development: RE: Receive and send data using vlan tag
- Bhardwaj
There should be no devicetree changes necessary to use the VLAN feature of the Ethernet.
You verified that the 8021q module is loaded.
You should be able to create a VLAN interface and configure it from the shell and then add... - Hi,
I am working on ethernet using vlan. I had used the ip command to create the vlan after that some data sent from another PC having vlan and run receive code on board to receive data but we didn't get any data. when we try these e...

- GG 07:47 PM Software Development: RE: how to access gpio using pio ip core in c code
- Hello,
I would look at the avalon memory mapped slave address in your signal tap. It's possible the hps is requesting a read from a different address for one of those two cycles. It's also possible two reads are queued up back to bac...

- Hi,
Yes, I am verified in Signal Tap only. and as off now like, we are able to do read and write HPS to FPGA using LW_AVALON_MM interface. In case of read from HPS, avalon_slave_read signal is being high for two clock cycles. Where as...

- GG 04:12 PM Software Development: RE: how to access gpio using pio ip core in c code
- It looks like you posted a couple different versions of your C code. Which one are you running and what does the output look like? How are you verifying the FPGA is receiving data from the HPS? Are you using signal tap?
Thanks,
Greg

- BK 03:16 PM Software Development: RE: how to access gpio using pio ip core in c code
- Hi,
In my implementation, the Avalon Memory Mapped interface automatically assigned a base address in platform designer with that address only I successfully sent an 32bit incremental data from the HPS to the FPGA and received it corr...

- DV 02:11 PM FPGA Development: RE: MitySOM-5csx custom board PL fabric ethernet access
- Hello,
For the reference project the makefile removes those lines from the sdc file before it does the build, if you aren't using the Makefile for doing the build then you need to manually delete those lines after running Platform Des... - BK 06:45 AM FPGA Development: RE: MitySOM-5csx custom board PL fabric ethernet access
- Hi,
Yeah, I am removed that two lines in dev_5cs/synthesis/submodules/dev_5cs_hps_0_fpga_interfaces.sdc, before updating this one i am getting 30-40% of packet loss in ping , as off now I am updated that one now i am getting 5-7% of ...

- DV 07:40 PM FPGA Development: RE: MitySOM-5csx custom board PL fabric ethernet access
- Hello,
I have verified that the reference design does meet timing when built via the makefile (ie make rbf). The makefile removes 2 incorrectly autogenerated clock assignments for the MAC clocks. The following lines need to be deleted...

- GG 06:58 PM Software Development: RE: how to access gpio using pio ip core in c code
- The most straightforward way to do that would be to create your own Platform Designer Component with an Avalon Memory Mapped Slave interface. (See https://www.intel.com/content/www/us/en/docs/programmable/683364/18-1/creating-components....

- BK 03:16 PM FPGA Development: RE: MitySOM-5csx custom board PL fabric ethernet access
- Hi,
with the provided reference project there is no packet loss but there are timing errors (screenshots attached) even after modified the reference project, as we said in first query, we observed similar timing errors with the same h...

- DV 01:39 PM FPGA Development: RE: MitySOM-5csx custom board PL fabric ethernet access
- It sounds like you are on edge for timing so please verify that your design meets timing via TimeQuest in Quartus. Also when you used the provided reference project you did not see this packet lose, correct?
Dan - BK 12:05 PM FPGA Development: RE: MitySOM-5csx custom board PL fabric ethernet access
- i had made HPS and emac Splitter Conduit signals to external in Platform Designer and I had assigned that conduit signals properly in top Module accordingly like, hps_0_emac0_phy_txd_o to rgmiib_emac_phy_txd_o and for that reference, ple...

- DV 01:08 PM FPGA Development: RE: MitySOM-5csx custom board PL fabric ethernet access
- Hello,
For the case that you are seeing 60% packet lose, what did you change in the reference FPGA project that was supplied in the bnet_mps project? Also have you verified that your project is meeting timing?
Best regards,
Dan
- BK 12:07 PM Software Development: RE: how to access gpio using pio ip core in c code
- Yes, I wanted to send the 256 BITS of raw data from HPS to FPGA. Can you give me the supplies for that.

- I just did a clean pull of the kernel and built it using the poky 3.0.4 sdk with no issues.
It sounds like either there was some old/other config in the build tree or your environment is different
my build did _not_ attempt to build th... - GG 01:20 PM Software Development: RE: How to access gpio using c code in yocto linux, which is created using PIO IP with HPS

Thanks,

- Hello,
Can you share capture of your console so we can evaluate what commands you are using and exactly what errors are being reported?
As long as you do not exceed resources on the FPGA you should be able to add the required pio ...
