MF 07:01 PM FPGA Development: RE: Ethernet Interface for MitySOM-A5E

Hi Max,
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 ... Mike Fiorenza

MK 06:14 PM FPGA Development: Ethernet Interface for MitySOM-A5E

Hello Sir/Madame,
I'm trying to add GbE IF to MitySOM-A5E (version: A5ED-B64-144-SRC-X)
In the Dev. Kit document this is described in p.16.
The Interface SGMII connects to Bank-2A
When I'm trying to add EMAC to HPS, it allows me only... Maxim Kanevsky

ZM 06:51 PM Software Development: RE: make_sd.sh doesn't take command line parameters

Hi Maxim,
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 ... Zachary Miller

MK 05:21 PM Software Development: RE: make_sd.sh doesn't take command line parameters

Hello Zach,
Let me please thank you for your time and support!!! We getting closer, but still have some issues...
We've got some progress.
In order to find a problem, we've replaced one-by-one the files in a script and found that wh... Maxim Kanevsky

ZM 04:15 PM Software Development: RE: make_sd.sh doesn't take command line parameters

You're correct that we don't post the rootfs_overlay, because in general it can have different things in it depending on the project's needs.
In your case, you just need to put the RBF into it per the instructions in this wiki section... Zachary Miller

MK 03:44 PM Software Development: RE: make_sd.sh doesn't take command line parameters

We have decided to build the reference design using the files from https://support.criticallink.com/redmine/projects/mitysom_a5/wiki/A5ED-B64-144-SRC-X_Quartus_Pro_2531_20260310
To make sure that we are building the correct way.
Here... Maxim Kanevsky

ZM 07:53 PM Software Development: RE: make_sd.sh doesn't take command line parameters

Thanks! The boot script (both boot.cmd and the compiled boot.scr) does have windows line endings, which I think unfortunately appears to be confusing U-Boot. The config_pll script appears to be okay, which I think rules out a git hook ch... Zachary Miller

MK 06:30 PM Software Development: RE: make_sd.sh doesn't take command line parameters

Hello Zach!!
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.
Thanks!!! Maxim Kanevsky

ZM 06:11 PM Software Development: RE: make_sd.sh doesn't take command line parameters

You're welcome!
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.
Would it be possible for you to z... Zachary Miller

MK 04:35 PM Software Development: RE: make_sd.sh doesn't take command line parameters

Thanks Zach!!!
Just to mention, we compiled mitysom-a5e-ref-dma project.
We've succedded to flash the SD card with Image and tried to run on MitySOM A5E board and getting following:

ZM 03:56 PM Software Development: RE: make_sd.sh doesn't take command line parameters

No problem, getting close!
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.
If so and you didn't want that, you could either run @gunzi... Zachary Miller

ZM 03:05 PM Software Development: RE: make_sd.sh doesn't take command line parameters

Hi Maxim,
The make_sd.sh script is intended to be run with bash, not POSIX @sh@. Could you please try running it as @./make_sd.sh@ instead of @sh make_sd.sh@ (keeping the rest of your arguments the same) and see if the errors are reso... Zachary Miller
