DR 02:35 AM PCB Development: RE: MSEL[4] and return current cap...: 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... David Rice

AF 11:34 PM PCB Development: RE: MSEL[4] and return current cap...: 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 Austin Franklin
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... David Rice

AF 06:54 PM PCB Development: MSEL[4] and return current cap...: 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... Austin Franklin

DV 06:10 PM FPGA Development: RE: Link missing on System Design Overview wiki page: 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.

SA 08:00 PM Software Development: RE: How to boot FPGA from U-Boot without having the uboot.env file in my SD card: 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 Shahad Alrawi

AF 06:54 PM PCB Development: RE: Standoff on Mounting Hole Locations page: 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.

I was wondering, I found in u-boot-socfpga/include/configs Shahad Alrawi

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... Shahad Alrawi

DV 04:54 PM Software Development: RE: Moving Forward with U-Boot and Quartus 22.1std: 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.

Best,

SA 04:13 PM Software Development: RE: Moving Forward with U-Boot and Quartus 22.1std: Great thanks Dan,
Worked with this warning!

DV 04:00 PM Software Development: RE: Moving Forward with U-Boot and Quartus 22.1std: 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... Daniel Vincelette
SA 03:24 PM Software Development: RE: Moving Forward with U-Boot and Quartus 22.1std: 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
