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

FS 12:14 AM Software Development: RE: MitySOM 5CSX SPI device not showing up in /dev: Hello Daniel,
I’m working with Evgeny on this and we’ve tried updating the compatible keyword to *cl,spidev* and we still don’t have SPI show up in /dev/, I have attached the updated dtsi file, also we are using kernel version 4.14.13... Franz Sattler

ZM 04:08 PM FPGA Development: RE: U-boot Error Message: Hi Jose,
I think your U-Boot environment may have become corrupted somehow: the "bad partition specification" error can occur when the partition number doesn't parse correctly. Since it _looks_ right in the error message, I suspect th... Zachary Miller

JB 05:21 PM FPGA Development: RE: U-boot Error Message: Hey Daniel,
Thanks for the help.
This is the full log:

I posted the UbootEnv.txt file. This is the print env output.

DV 03:17 AM Software Development: RE: MitySOM 5CSX SPI device not showing up in /dev: Hi Evgeny,
Which branch of the kernel are you using? Mainline linux removed the keyword *spidev* from the compatible list of the spidev driver around the 4.x branches. The socfpga_mitysom5csx_leigh.dts uses an earlier kernel.
If yo... Daniel Vincelette

EG 11:44 PM Software Development: MitySOM 5CSX SPI device not showing up in /dev: Hello --and hoping that someone can please help me with the following.
I’m trying to get the SPI device to show up in /dev. I added spidev for SPI0 to my dtsi file like in the socfpga_mitysom5csx_leigh.dts file from https://support.crit... Evgeny Galyaev

DV 08:30 PM FPGA Development: RE: U-boot Error Message: Hi Jose,
I'm going to need a bit more info to help you get further. Can you provide your full console log? Also is the ubootenv you provided a copy and pasted from the uBootMMCEnv.txt file or is it the print out of running "print env"... Daniel Vincelette
