- MF 03:31 PM Software Development: RE: cl_msgdma.ko has the wrong version
- Hi Samuel,
We plan to integrate this kernel module into our kernel in the near future, so this would be handled automatically for the end user.
However, until then you could explore options such as adding a recipe into the Yocto bu...

- SP 10:03 PM Software Development: RE: cl_msgdma.ko has the wrong version
- This way works to make a compatible version of cl_msgdma.ko. (/) :D
Is there a way to build it inside the docker container at the same time we build the file system.

- Hi Samuel,
The Wiki instructions say to deploy the compiled kernel and kernel modules to the SD card as well. This way you ensure that all binaries are in sync and the vermagic matches.
You can however try to work around this by ma... - When I try to insert the cl_msgdma kernel module I get the following message.

- Hi Max,
As mentioned in the "HPS/FPGA Shared Memory thread":https://support.criticallink.com/redmine/boards/75/topics/7293 the data errors you saw were caused by a bug in my xor data generator core. This will be resolved in our next r... - MK 03:32 PM Software Development: RE: make_sd.sh doesn't take command line parameters
- Hello Zach,
We are back to test DMA example design.
Do you have any update regarding the failure that we saw??
Thanks,
Max

- MF 02:44 PM FPGA Development: RE: HPS/FPGA shared external memory
- Hi Max,
Just to make sure we're aligned on the DMA example — what it demonstrates is really the same use case you're after: exchanging data between the FPGA and the ARM through HPS DDR. The example uses the F2H (FPGA-to-HPS) path. The... - MK 01:42 PM FPGA Development: RE: HPS/FPGA shared external memory
- Sorry, forgot to mention, as you suggested, ve tried first DMA example design and we tried to run it. But for now we are interesting in shared memory access, so that's why we are trying FPGA to SDRAM
- MK 01:40 PM FPGA Development: RE: HPS/FPGA shared external memory
- Hello again,
I've created a project based on mitysom-a5e-ref-base project.
We made following modifications:
- we added FPGA to SDRAM Subordinate Bridge into HPS Subsystem
- we added AVMM to AXI4 Bridge (because all of our modules a...

The "Agilex-5 datasheet":https://docs.altera.com/r/docs/813918/current/agilextm-5-fpgas-and-socs-device-data-sheet/i/o-pll-specifications specifies the Input clock frequency source from HVIO clock input at a max of 156.25 M... - Hello,
I'm working on an FMC PCB that will interface with the MitySBC-A5E. The board contains an ADV7611 HDMI receiver and an ADV7513 HDMI transmitter, both of which have decoded pixel bus inputs/outputs at 3v3 logic levels. The pixel...

- Hello Mike, thanks a lot. Yes, not it is working
Max - MF 04:51 PM FPGA Development: RE: Signal Tap not working
- Hi Max,
As shown on the right side of your screenshot, you do not have the correct device selected. You need to select Device: @2 which is the FPGA. @1 device is the ARM.
Let me know if changing that drop box resolves your issue.
... - Hello !!!
We are using mitysom-a5e-ref-base as a reference and we've added FPGA2SDRAM port to HPS and some Avalon Memeory-Mapped generator to initiate some traffic from FPGA to the SDRAM. We also addd Signal Tap to see if the generator ...

- Hi Samuel,
To use a USB-to-Ethernet adapter, the Linux kernel needs to include the appropriate USB networking driver for the adapter chipset.
For the USB Ethernet adapters we have been using, the required kernel option is: - I am working with Maxim on the same machine.
We would like be able to make usb to ethernet adapter work. - MK 09:09 PM FPGA Development: RE: HPS/FPGA shared external memory

Thanks a lot for your answer. I've found the same after I posted the question...
Thanks,
Max - MF 08:55 PM FPGA Development: RE: HPS/FPGA shared external memory
- Hi Max,
Yes, this is possible on the Agilex 5 platform, but the external memory connected to the HPS EMIF is not intended to be modified directly through the hidden emif_io96b_hps.qsys block.
For FPGA logic to exchange data with th... - Dear Sir/Madame,
I would like to create my own design based on mitysom-a5e-ref-base, but with shared between HPS/FPGA external memory. The purpose of this is to exchange data between HPS and FPGA. We would like to try this and see if ...

Apologies on the delay for your first question, my colleague who's more familiar with the DMA example is looking into that now. I'm not sure yet when we'll have an answer for you, but he is able to (intermittently) reproduce t... - MK 06:17 PM Software Development: RE: make_sd.sh doesn't take command line parameters

- Hello Zach,
Yesterday, we din't pay attention, but actually DMA test fails on Rx side. We run few times and it faild always in the same index.
We will try on other unit (we have 2), but do you have any idea why it can fail??

- Hi Max,
Thanks for the feedback, I can definitely see how in this case that wording was misleading. In general it is not mandatory (e.g., some device tree changes do not require an updated Image file), but I'll make a note to see if w...
