- MF 08:29 PM FPGA Development: RE: MitySOM-5CSX Dev Kit – USB OTG J401 not detecting USB devices
- Hi Atef,
We just doubled checked on our side that the image you mentioned (Yocto (Poky 2.4.4, kernel 5.4.23-yocto-standard)) works as expected on the development kit.
Can you provide what type of USB OTG adapter you are using? We h... - Hello,
I am using a MitySOM-5CSX SOM on the standard Critical Link carrier (development kit) with Yocto (Poky 2.4.4, kernel 5.4.23-yocto-standard). I am trying to validate the USB OTG port J401 in host mode with a USB flash drive.
At b... - AF 07:18 AM FPGA Development: RE: Ethernet PHY configuration and SSH access

- Hi Atef,
You should be able to do this via ethtool: - AF 02:50 PM FPGA Development: RE: Ethernet PHY configuration and SSH access
- Hi Zach,
Could you please generate a Linux image for the 5CSX-H6-4YA based on the Linux image available at the following link (https://support.criticallink.com/redmine/projects/mityarm-5cs/wiki), but configured so that the Ethernet li... - MW 10:25 AM FPGA Development: RE: Ethernet PHY configuration and SSH access
- Hello,
For layout, the two groups you have outlined in your schematic snippet should be matched in length and ideally be on the same layer. The clocks should be separated from the data lanes by at least 5x trace width. We usually ... - AF 08:47 AM FPGA Development: RE: Ethernet PHY configuration and SSH access
- Hi Zach,
Just a quick update on my side.
I am now able to communicate over Ethernet with our custom carrier board. However, in some cases I still observe data loss that results in dropped connections. My current suspicion is that thi... - AF 08:15 AM FPGA Development: RE: Ethernet PHY configuration and SSH access
- Hi Zach,
Thank you for your reply.
I ran ethtool eth0 | grep PHYAD on my system, and it confirms that the PHY is detected at address 3, as shown in the attached screenshot.
Could you please let me know if the Ethernet hardware section...

- ZM 05:40 PM FPGA Development: RE: Ethernet PHY configuration and SSH access
- Hi Atef,
The image you downloaded should have an SSH server (OpenSSH) running by default, yes. @ps@ by default doesn't show all processes, which is why the grep in your screenshot didn't find it. Running @ps -A@ or @ps aux@ should con... - Hello,
I am working with a MitySOM-5CSx module on my own custom carrier board and I am seeing different behavior depending on which SD card image I use. I would appreciate your help to understand the correct configuration.

- Atef,
Can you make sure you have the MSEL set appropriately per the table below?
!image.png! - Hello,
I am trying to test bitstream encryption on a MitySOM-5CSx evaluation board and I am running into an issue during boot.
Here is what I have done so far:
In Quartus, I enabled bitstream encryption and generated an encrypted RBF ...

- AF 03:57 PM FPGA Development: RE: Using the design security for MitySOM-5CSX
- Hello,
I would like to encrypt the FPGA bitstream on the MitySOM-5CSX. I have been referring to Intel’s application note AN557 (Using the Design Security Features in Intel FPGAs) to understand how to enable bitstream (.rbf file) encrypt...
