- MF 03:43 PM Software Development: RE: make_sd.sh doesn't take command line parameters
- 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...

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,

- 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

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...

It's fine to have multiple folders in @/lib/modules@, although you could delete the yocto-standard one if you wanted to reclaim the storage space. Just be aware that if you do that for the kernel you're using by mistake, some ... - MK 08:10 PM Software Development: RE: make_sd.sh doesn't take command line parameters

Glad to hear the base design is working now! And no problem asking questions, most likely they'll help someone else too. :)

Thanks again for your help.
So, I’m not sure what’s was wrong, but now we are able to create our own SD-Card image by compiling and building mitysom-a5e-ref-base.

That USB dongle should be fine. Our reference design SD card should have the drivers pre-installed for that to work.
In terms of production silicon, we are hoping to have them available sometime this summer for customers.

If you are trying to use the SGMII Ethernet interface that goes to J19 on the board then this will not work due to limitations with Engineering Silicon.
In order to hook this up you need to enable GMII for FPGA in the HPS ... - Hello Sir/Madame,

Happy to help!
It looks like this is a case of the JIC and RBF files not matching.
In general, the JIC and RBF need to be both created from a project that has the same HPS I/O and clock settings. Altera documents this ... - MK 05:21 PM Software Development: RE: make_sd.sh doesn't take command line parameters

I've uploaded mitysom-a5e-ref-dma.tar.gz (1.29G) - I've compressed the whole folder.
We didn't changed the design and scripts.

The build seems to have partially worked since it was able to boot into U-Boot proper after the SPL, but past that it seems unable to load anything from the SD card for some reason.

Did the script produce sd_card.img.gz instead? You're giving it flags for both gzip (@-g@) and zip (@-z@), and gzip should be taking precedence.
