- 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...

- Seth,
I got the GPIO pin on the FPGA side to work as you described. This is just as good as having an LED because the whole point was to have an example to study how the GPIO is triggered from the linux side,i.e. how the command "worms...

- MF 08:59 PM FPGA Development: RE: Clarification regarding LED 4 on MitySOM-5CSX DevKit
- Atef,
Okay that makes sense! In that case, I would look into Arm Developer Studio then. You should be able to obtain an evaluation license and it should be able to accomplish what you are asking for. There are potential open-source so... - AF 08:50 PM FPGA Development: RE: Clarification regarding LED 4 on MitySOM-5CSX DevKit
- Mike,
Thank you for your response, I’ll have a look at it.
I was focusing on using JTAG because I’m having an issue with SD-card boot on the carrier board I designed.
Thanks again for your help. - MF 04:03 PM FPGA Development: RE: Clarification regarding LED 4 on MitySOM-5CSX DevKit
- Atef,
If you see our Wiki page here: https://support.criticallink.com/redmine/projects/mityarm-5cs/wiki we post full SD card images for the development kits. These SD cards will use U-Boot as the bootloader which the HPS loads first t... - AF 03:50 PM FPGA Development: RE: Clarification regarding LED 4 on MitySOM-5CSX DevKit
- Mike, Thanks for your response. Yes, I was trying to load the compiled C code binary directly to the HPS via JTAG. Since there is no tutorial available for that method, could you please send me (or point me to) your tutorial explaining h...

- Atef,
Glad to hear you resolved your JTAG issue. Can you elaborate on how you are trying to load the HPS portion? Are you trying to load binaries directly to the HPS via JTAG? Unfortunately we do not have any tutorials at the moment t... - AF 10:31 AM FPGA Development: RE: Clarification regarding LED 4 on MitySOM-5CSX DevKit
- Thank you Mike, the system works by reversing the USB Blaster connection. I have another question please: Do you have a tutorial that explains how to load the HPS portion using WSL on Windows? Thanks.

- Atef,
From your picture, it looks like you have the JTAG pod plugged in backwards. Pin 1 on your ribbon cable does not align with Pin 1 on the JTAG adapter board.
Please try rotating your pod connection and report back.
- Mike - AF 04:13 PM FPGA Development: JTAG programming issue on MitySOM-5CSX DevKit with Quartus (Windows 11)
- Hello,
I’m trying to program a MitySOM-5CSX board via JTAG using Quartus on Windows 11, but I encounter an error immediately when starting the operation.
I'm using :
-Tool: Quartus [version], Windows 11
-Interface: USB-Blaster [I...

- Hi John,
Hope you are well. I'll go ahead and try and answer your questions and comments below!
* @Is there a specific example program/script, that I might have missed, to exercise an LED connected to the FPGA from a program/script...

- In the above, I don't know where the strike-thru lines came from.
- JI 01:12 AM FPGA Development: RE: Building the MitySOM-5CSX
- Additionally, in comparing the provided sd card with the built one, I found that the directory, *scripts_auto* , does not exist. This is where the LED test (and some others) lives on the provided card.
Also, the following listing retu...

- JI 02:47 AM FPGA Development: RE: Building the MitySOM-5CSX
- This past weekend I was experimenting with the provided sd card and the examples. Specifically the LED example to light and change colors of D1 on the mitysom module. I got that to work ok. After doing a little digging, it appears tha...
