- 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...

- Hi Michael,
p/n: 80-000642RI-1
s/n: 14008623
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?

You would use the *editenv* command.

FPGA Development: RE: Load FPGA from uboot
- Hi Dan,
How do I change the fpgaimage uboot variable?
Thanks,
Jack - DV 04:28 PM FPGA Development: RE: Load FPGA from uboot
- Hi Jack,
That SD card image will automatically load the rbf file that is on the second partition at /home/root/mityarm_5csx_dev_board.rbf during uboot.
If you would like to boot a different rbf then you will need to update the *fpg... -

FPGA Development: Load FPGA from uboot
- Hi,
I tried to follow the instruction in "http://rocketboards.org/foswiki/Documentation/LoadingFPGAFromUBoot".
But I ran into difficulties where it complains that my file format is not correct.
The development kit sd card image ... -

Software Development: Auto-start script
- Hi,
I'm trying to have both my FPGA loaded and a software script running on initializing the system.
Any suggestions?
I know the FPGA can be loaded via uboot, but what about the script. Also, if FPGA is loaded via uboot, will be...
