DV 07:35 PM Software Development: RE: MitySOM 5CSX-H6-53B-RC not booting

Hi Franz,
We do have a reference SD card for the 5CSX-H6-53B on our wiki page: https://support.criticallink.com/redmine/projects/mityarm-5cs/wiki#Variant-Specific
Here is a direct link to that SD card: https://support.criticallink.... Daniel Vincelette

FS 06:53 PM Software Development: MitySOM 5CSX-H6-53B-RC not booting

Hello,
We are having some difficulties getting the MitySOM 5CSX-H6-53B-RC board to boot with our firmware, we get the following error with SDRAM shown in attached image. Our firmware works fine with the MitySOM 5CSX-H6-42A-RC and we a... Franz Sattler

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

Hi Jose,
You can make the following changes to the U-Boot environment to enable Ethernet: Zachary Miller

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

Hi Jose,
Are you using a MitySOM-5CSX Development kit board, or a custom carrier board?

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
