Interesting. I don't believe there is a guarantee by the C standard as far as placement of memory. Each implementation may vary in the mechanics as long as the end result is a block of memory of at least the size requested. ... - Hi all,
I have a series problem with memory on ompl138, that the program.

Hello,
As I have a problem to set up the ADC with SPI interface through ARM, I found that I have to recompile kernel to support analog expansion suite from the page

Whenever you change anything to do with HPS pin assignments, you will need to rebuild the preloader and update it on the boot media (SD card or ROM)

Unsure whether to post this under the software or FPGA topic.
We are transitioning from a mostly working system developed on the Mitysom5CSX Devkit to a custom carrier board design (Cyclone V, 5CSX-H6-4YA-RC). In the previou...

Is there any specific doc. for the 5CSZ build? e.g. driver name, build instructions, code location, etc. Any examples kicking about? Do you know if anybody has tried this on the 5CSX?
Kind regards...

We will try to use Analog Expansion Kit provided by Critical Link.
btw do you have the 3D step file for the carrier kit (The Industrial IO Development Kit)?
we need that to design our enclosure.
