- Sorry if I wasn't clear. The caps are optional. They might help in a worst case situation, but for most designs they are overkill. Leaving one off won't be a problem. If you are doing a design and have the option to put them on, it w...

- Hi David,
I understand that, but the eval board only has them on MSEL[3:0] and does not have one on MSEL[4]. So, should there be one on MSEL[4] on any design using the MitySOM or not?
Thanks,
Austin - DR 07:38 PM PCB Development: RE: MSEL[4] and return current cap...
- The intention of the caps to ground on these signals is to allow some high frequency ground currents from the SOM I/O's going off-SOM to have additional paths to ground, since the MSEL signals (and other listed signals) are essentially D...

- 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...

- Thank you for bringing this to our attention, I've updated the text on that wiki page so it now links to our reference project.

- 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)

- 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...
