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... John Iannuzzi

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... Mike Fiorenza

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. Anonymous fpga

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... Mike Fiorenza

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... Anonymous fpga

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... Mike Fiorenza

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. Anonymous fpga

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.

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... John Iannuzzi

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... John Iannuzzi

Hi Seth,
For the 1st bullet point above I followed your instructions using the *command line* and it worked. Great!
I login with *root* get the prompt, *root@mitysom-c5:~#*
I think the *unmount* instruction was the key.
Below, is ... John Iannuzzi
