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 ... Chris Weinman

Hi Chris,
We will look into it. Can you post the module type and serial number just so we know your exact configuration?

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/... Daniel Vincelette

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: Daniel Vincelette

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... Daniel Vincelette

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.

02:42 PM 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... Anonymous
