FS 02:58 AM Software Development: RE: MitySOM 5CSX SPI device not showing up in /dev: Hello Daniel,
We tried changing the keyword to *rohm,dh2228fv* but it still does not show up in /dev/. Is there anything that might be missing from the kernel? We did add “CONFIG_SPI_SPIDEV=y” but is there more needed? You linked a sp... Franz Sattler

JB 06:17 AM FPGA Development: RE: U-Boot Network Setup (MitySOM-5CSX-H6-42A): That did it. Jose Berlioz

ZM 03:10 PM FPGA Development: RE: U-Boot Network Setup (MitySOM-5CSX-H6-42A): Hi Jose,
You can make the following changes to the U-Boot environment to enable Ethernet: Zachary Miller
JB 07:32 AM FPGA Development: RE: U-Boot Network Setup (MitySOM-5CSX-H6-42A): Hey Mike,
Yes, I have a 300Mbps switch, but I can test it in a faster one. I am also testing it in the devkit, not the custom board.

When yocto comes up, it looks like it is able to get to 100Mbps: Jose Berlioz
MW 03:37 AM FPGA Development: RE: U-Boot Network Setup (MitySOM-5CSX-H6-42A): Hi Jose,
Are you using a MitySOM-5CSX Development kit board, or a custom carrier board?
The first couple of lines: Michael Williamson
JB 02:27 AM FPGA Development: U-Boot Network Setup (MitySOM-5CSX-H6-42A): Hello,
I was trying to load the kernel and fpga files through a TFTP server. I have to use a static IP for this as a requirement (cant use dhcp).
Is there any setup I have to do besides establishing environment variables on U-boot? I c... Jose Berlioz

JB 03:54 PM FPGA Development: RE: U-boot Error Message: Hey Zach,
Thanks for your reply! That worked. I was under the impression I only needed to rebuild the Preloader and U-boot if I changed the HPS.
Thanks for clarifying that.

ZM 07:38 PM FPGA Development: RE: U-boot Error Message: Hi Jose,
The issue is device tree nodes for FPGA peripherals that don't exist in your FPGA. As a quick-fix, I'm attaching a precompiled device tree you can include in the filesystem to make your SD card boot. You'll want put the devic... Zachary Miller
JB 04:19 PM FPGA Development: RE: U-boot Error Message: Hey Zach,
I included all three in the SD Card when I rebuild the SD Card. Also, the SOM yellow LED turns off and the green LED turns on.
Sure, I can do that. I am including a zip file with the SD Card Image and the individual files ... Jose Berlioz

ZM 08:13 PM FPGA Development: RE: U-boot Error Message: Hi Jose,
Thanks for the info. When you rebuilt your SD card image, you included your all three of your new preloader, U-Boot, and FPGA, correct? If there's a mismatch between those three binaries it can cause the kernel to hang like t... Zachary Miller
JB 04:21 PM FPGA Development: RE: U-boot Error Message: Hey Zachary,
Thanks for your help. Yes, that's as far as it goes. I flashed on a different SD Card and it has the same issue. Also, I can flash it with a working SD card img from criticalLink and that one loads.
Answering your questi... Jose Berlioz

ZM 09:07 PM FPGA Development: RE: U-boot Error Message: Great, I'm glad that helped!
Is "starting kernel" as far as it boots? As a quick sanity check, could you try flashing a fresh SD card from the pre-built image on our wiki? There are download links here: [[wiki#Variant-Specific]] (base... Zachary Miller

JB 10:17 PM FPGA Development: RE: U-boot Error Message: Hey Zach,
Thanks for the ubootenv.bin file, that seem to have done the trick and I was able to load the fpga image. I seem to have issues with the kernel though.
The console freezes at the end and Yocto never loads. I am using the mi... Jose Berlioz
DV 07:11 PM Software Development: RE: MitySOM 5CSX SPI device not showing up in /dev: Hi Franz,
I would recommend switching to our socfpga-4.9.78-ltsi branch that can be downloaded from git repo: https://support.criticallink.com/gitweb/?p=linux-socfpga.git;a=summary, which our current stable branch. This has a few fixe... Daniel Vincelette
