- 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 ... - MW 12:30 PM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P Software Development: RE: Uart issue in Am62P
- Hi Rajkumar,
Is the only difference between the AM62P working and not the use of the application code vs. the loopback code?
Are you testing with the same data / BAUD rate in loopback vs. application? Same hardware configuration?
... - Hi,
We are working with the Critical Link AM62P and AM62a SoM and have installed Debian 13 on am62P the system. We are currently using UART5 for communication, and we are facing an issue specific to the AM62P module.
Initially, we ...

- AF 03:57 PM MitySOM-5CSX Altera Cyclone V 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 MitySOM-5CSX Altera Cyclone V 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 MitySOM-5CSX Altera Cyclone V 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 MitySOM-5CSX Altera Cyclone V 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 MitySOM-5CSX Altera Cyclone V 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...
- MF 03:42 PM MitySOM-5CSX Altera Cyclone V FPGA Development: RE: Clarification regarding LED 4 on MitySOM-5CSX DevKit
- 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 MitySOM-5CSX Altera Cyclone V 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.

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.

- SL 04:38 PM MitySBC-Agilex5 FPGA Development: RE: MitySBC A5E
- Thank you for the information. I am guessing the pre-installed FPGA does not enable FMC_EN_3V3.
I will start with one of the available reference projects.
Best regards, Sung Lim - MW 04:24 PM MitySBC-Agilex5 FPGA Development: RE: MitySBC A5E
- Hi Sung,
From the datasheet (page 14):
"All power to the FMC connector is gated by FMC_EN_3V3 which is tied to pin CG134 of the FPGA."
This will enable the +12V FMC power supply and the +3.3V FMC power Supply. VADJ should alrea... - Two questions:
1. On the prototype board, FMC +12V and +3.3V do not appear to be driven. Is there a strapping option to supply the two voltages from the SBC?
2. Would it be possible to obtain the Quartus pro project for the base FPGA?...

- MW 06:44 PM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P PCB Development: RE: SOM_62P Reset on LED_RTN
- Wondering if you could add a LPF filter (cap + R) across your FET to make the switch less aggressive. Kind of hacky, but it might work.
- AD 06:28 PM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P PCB Development: RE: SOM_62P Reset on LED_RTN
- That explanations seems probable, if I have any free time coming up I'll play around with the circuit on our side to get it working reliably.
For the time being we'll continue to not switch LED_RTN.
Thanks for the rapid reply! - MW 06:15 PM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P PCB Development: RE: SOM_62P Reset on LED_RTN
- Hi Adrian,
Haven't seen this before.
This is a snippet from the SOM schematic related to the Power Good LED and the LED_RTN Net:

As you can see, the PMIC_PGOOD is AND-ed into the main MCU_PORz. It is an... - We have a series of switchable LEDs on board for basic debugging of various on-board supplies, and for completeness I've included the ability to sink current from LED_RTN (pin 2 on SOM) to get some visual output from the SOM.
