- MW 07:42 AM Software Development: RE: Very high TX packet loss on gigabit Ethernet
- Hi Chris,
We've had this module deployed on a couple of different designs as well as the DevKits and I don't think we've had to tweak the pad skews and I know that our packet loss was pretty much negligible. Our validation test uses ... - Hi,
I've been having trouble getting gigabit Ethernet working on a MitySOM-5CSX dev kit using a preloader, u-boot and linux built as per the instructions at [[Building_u-Boot_and_Preloader]] and [[Yocto_for_MitySOM-5CSX]]. It works fin...

- DV 03:28 PM Software Development: RE: U-boot not bringing Linux kernel up correctly
- Hi Chris,
We've also just recently found that that commit is causing troubles for our 5CSX dev kit as well. It appears to be adjusting the SDRAM row size to 4GB instead of 1GB in order to workaround an SDRAM errata. We are currently l...

It's in a dev kit at the moment. Our base board borrowed heavily from the dev kit, so there shouldn't be any significant differences there.
I have tried other modules to no avail.
I did ... - MW 07:52 AM Software Development: RE: U-boot not bringing Linux kernel up correctly
- Hi Chris,
We will look into it. Can you post the module type and serial number just so we know your exact configuration?
-Mike - Hi,
I've built the preloader, U-Boot, Linux kernel and filesystem as per the instructions at https://support.criticallink.com/redmine/projects/mityarm-5cs/wiki/Building_u-Boot_and_Preloader and https://support.criticallink.com/redmine/p...

- DV 01:07 PM Software Development: RE: Auto-start script
- Hi Jack,
Is your software designed to be executed in linux?
If so then you will need to have linux execute it on startup and not uBoot. Here is a brief description of what needs to be done: https://support.criticallink.com/redmine/... - DV 10:44 AM Software Development: RE: Mounting the backing_file
- Hi Paul,
loopback devices are not built into the provided kernel. You will need to either build it in or add it as a module to your kernel.
Once loopback support is added to your kernel, you should be able mount it with following: - Ok so the enable-usb script works and my PC sees the storage made available by the dev kit but what is the mount command to get the backing_file available on the arm processor?
The docs state -

- Hi Jack,
You would use the *editenv* command.
