- Hi John,
Glad you were able to work through the stuff I described and get things working, you're welcome!
Yes, great observation. Lines 549-562 are the I/O available on the partial header, while the rest are available on the full h... - JI 12:28 PM FPGA Development: RE: Building the MitySOM-5CSX
- Hi Seth,
I found all the stuff that you described below and have started to study the .vhd file. Thanks. I also got bit 30 to work as described.
That said, it appears (from the .vhd file, lines 549-562) that those I/Os are only avai...

- Hi John,
Apologies, I believe I sent you an internal link. The schematic you have is correct and has the same connections for the HSMC connectors. They can be found on page 6. Hope this helps, apologies once again for any confusion!

I'll take a look. Also, I get a page load error with the 1st link :

- Hi John,
Thank you, happy (belated) Holidays to you as well! I appreciate your patience for a response as I was out of office. Glad you were able to rebuild the device tree and get the RGB scripts to work.
I went ahead and took a l...

- Hi Seth,
Happy Holidays!
Ok, I was able to rebuild the device tree as you instructed and got it all to work, including the RGB scripts. It appears now I have a fully operational sd card image.
Back to the FPGA GPIO. So I connected...

- 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,
