- Hi Franz,
Based off your boot log the board is stuck at the preloader, before getting into u-boot. The preloader/u-boot are built using outputs from the firmware build, the preloader get's it pinmux/DDR settings from the options you s... - FS 12:14 AM Software Development: RE: MitySOM 5CSX-H6-53B-RC not booting
- Hello Dan,
I made the changes you suggested and the same issue is still there, at this point I don't think the issue is with the firmware files. You mentioned that the preloader/u-boot images would be different, are there any other ch...

- Hi Franz,
One difference that stands out to me is the INPUT/OUTPUT TERMINATIONs used. Because the SOM uses a different RZQ value than the defaults that quartus use please change the HPS DDR INPUT_TERMINATION/OUTPUT_TERMINATION for the... - FS 02:23 AM Software Development: RE: MitySOM 5CSX-H6-53B-RC not booting
- Hello Dan,
I have attached the .qsys and .qsf files. These have the instances added as well as the row address width set to 16 so I'm not sure what other change is needed, maybe the clock needs to be changed for the 53B-RC?
Thanks,...

- Hi Franz,
For the issue with the 53B SOM hanging at "Initializing SDRAM ECC" the device tree doesn't come into play, at this point the SOM would only care about the preloader. From a highlevel your soc_sys.dts looks ok.

- Hello Dan,
I did already have those instances added to my .qsf. Before I share my .qsys and .qsf files I would like to verify if my device tree files had the correct changes, I have attached all the ones being used here. The changes b...

- Hi Franz,
I don't believe changing the pin mux like you have would cause the preloader to hang at initializing the DDR, this normally occurs if the row width wasn't adjusted to account for the extra size. Also you are right the row ad...
