Nios V uC/TCP IP Failed

Hi,

I may need some days to debug this issue, I shall update to you again in the next few days.

Hi,

From my findings, the signal issue you mentioned, it seems that it has something to do with some settings that need to be tweaked.

I will further investigate towards that and get back to you soon with some suggested workaround.

Thanks for your patience.

Hi,

Does the issue always have the "ff_rx_rdy" high? OR do you have it work at random times?

One of the workaround I could find was implementing a reset. I am not that familiar with the TSE IP, you could try to perform a reset signal:

Hi,

From the STP content below, I think the ff_rx_rdy is a signal from DMA.

After downloading the sof and elf, the system booted with ff_rx_rdy high, which indicate to the core ready to receive data.

But it went low after with the network connected..

Therefore I guess there are problems on the msgdma ..

I read back some register settings on TSE core, and thought it should be configured correctly.

Hi,

I modify the design with Nios V to EMIF through a memory mapped clock crossing bridge and DMA through another bridge.

But for unknown reason the DMA bridge is not running...

I STP the bus and found only Nios V is running..

Any suggestions ? DMA driver or ...

Hi,

I believe so, as

Hi,

Since we currently do not have the example for the Simple Socket Server with EMIF for Nios V, can you try with the OCRAM as per the Nios V handbook?:

https://www.intel.com/content/www/us/en/docs/programmable/726952/23-4/processor-using-the-microc-tcp-ip-stack.html

Try with OCRAM, if it works then I can recommend to try with EMIF.

HI

I am Jingyang and I will be taking over the case from Eber.

Sorry for the late response as there are a surge in cases at the moment.

Please give me sometime to try get the example design running and try probe the behavior of the ff_rx_rdy pin.

Hi

Sorry there is a current surge in case and I will need more time in this case.I managed to run the example design and able to connect to the board through Telnet. Currently I will need more time to acquire the signalTap waveform.

Previously when you switch the Example Design to DHCP. Are you able to connect to the board through Telnet?

Hi Jingyang,

Thank you for the update.

So you can run the example design on the Cyclone 10 GX device and can telnet it?

If this is the case, would you share me the example?

As I never have any change to connect to the board.

BRs,
