JK 08:28 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: SPI Comm - can transmit data from Linux, but not receive

Are you referring to modifying the FPGA such that MOSI is connected to MISO?
If that works, it might indicate that somehow our MISO signal isn't hooked up correctly in the FPGA (which I'd be surprised by due to another test described ... Jared Kirschner

MW 06:43 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: SPI Comm - can transmit data from Linux, but not receive

Have you tried using the Loopback option to see if you can just loop back the command data and if RX is OK?

Code Composer is very finicky about exact paths for the Platform.tci file. It's possible you went too many, or too few directories in when specify this information under Properties->Build->TCONF->General Options or when creating the DSP/... Jonathan Cormier

MR 10:27 PM MitySOM-5CSX Altera Cyclone V PCB Development: Standoff on Mounting Hole Locations page

I believe there is a small errata on the [[Mounting_Hole_Locations]] page.
At the bottom it states... "Standoff: McMaster Carr PN - 91115A510" ... This is not an actual part number in McMaster.
I think the last two numbers where switch... Michael Ruen

Your right I can't find the u-boot-tools archive anymore.
Luckily the mkimage tool is built by u-boot. So it can be copied to the system so its available in the path.

Hi Jonathan,
We followed the instructions in the link, but we continue having problems to get the U-boot-tools package, it updated some other things, but we got this error:
