- The dev board has MSEL[3:0] with 1000pF caps, and MSEL[4] does not have a cap, unless I missed it. In the design guide:
7.4 Return Currents
The module’s edge connector has GND connections distributed along the interface pinout to ma...

- Hi everyone,
For anyone who is reading, I have figured it out and I hope this will help you.
The U-Boot is running a script, see the bootcmd below - (posted on behalf of a customer)

it says:

- Part number 91115A501 is a 3/8" size standoff (1/8" tall, 4-40, hex). The one on the deb board I have is 1/4" size, which is part number 91115A160.

- Hello,
I was wondering, I found in u-boot-socfpga/include/configs - Hello,
As a follow up from this question:https://support.criticallink.com/redmine/boards/45/topics/6501
Luckily, I was able to compile U-Boot 2019 from your CriticalLink repo and compile the Linux kernal and Yocto Rootfs as specifi...

- Yes, I would say that's ignorable. We don't plan on removing the driver from our 2019.10 branch. Though I'm not sure if it's still in any of the newer u-boot branches that Intel is hosting.

- Is that ignorable?
Best,

- Great thanks Dan,
Worked with this warning!

- I've seen this error in the linux kernel, it's due to using a newer version of GCC (I think GCC 10 was were this broke). I beleive this patch should resolve the issue: https://github.com/altera-opensource/u-boot-socfpga/commit/018921ee79...

- Hello Dan,
Thank you so much!
I tried to compile the criticalLink repo of U-Boot (socfpga_v2019.10) as in the instruction: https://support.criticallink.com/redmine/projects/mityarm-5cs/wiki/Building_U-Boot_and_Pre-loader_2019

- Hello,
Running in 1 bit mode was a bug in our reference dts, which was fixed in the following patch: https://support.criticallink.com/gitweb/?p=linux-socfpga.git;a=blobdiff;f=arch/arm/boot/dts/socfpga_mitysom5csx_devkit.dts;h=f7ce4754... - Hi
We have an SD card connected to the MitySOM-5CSX the same way as on the evaluation platform with 4 data lines.
When running SD card read tests we have discovered that the read speed is only 6 MBytes/s, and that is not fast enough i...

- Hello,
We do have a reference for building using the newer flow for the preloader/bootloader but it's for the socfpga_v2019.10 branch and Quartus 20.1, which can be found here: https://support.criticallink.com/redmine/projects/mityarm... - We are currently using 5CSX-H6-42A-RC with our own base board.
I have recently upgraded Quartus 18.1 to the more recent version Quartus Prime 22.1std. Additionally I made changes to the Platform designer in the HPS system.
So in order ...
