Trying to boot DM368 board with linxu 2.6.32 (either from TI or from RR), but I could not get any console output at all. I got u-boot output via rs232 though, so that means the hardware platform work. But could not see anything from Linux.
Could some upload a working uImage or shed some light here?
bootargs is 'console=ttyS0,115200n8 mem=60m root=/dev/nfs nfsroot=<blahblah>".
Below are two logs from TI and RR 2.6.32 kernel

Have you tried using an Installer SD or an Image at a SD card? The images are available at:
Just download the SD image that you need and boot from a SD.
You can use a DM365 SDK, everything should work fine, the only difference is the speed clock. If you want to get DM368 SDK demo, please let us know.

Yes, I have tried SD card boot and that worked. But nand boot is desired. Please help! Thanks.
There is an installer SD at:
The file is: Leo365Eval2011Q2_JFFS2.zip
You will need to boot from SD, the installer SD will install: uboot, kernel and file system. After using the installer SD you will be able to boot from nand normally.
i.c. I have tried the SD img and RTSP img, never thought about the JFFS2 image. Now the board boots up from the nand. Can we reproduce the JFFS2 img from the eval 365 SDK?
Yes, I would love to test the dm368 DEMO, especially for 1080P30 video!
Anyways, thanks a ton!
Yes you can install the file system from the 365 Eval SDK:
For the DM368 DEMO you will need the DM368-EVAL2011Q2 SDK but 1080P support isn't available at the eval version at this time
Could you please tell me where I can get the DM368-EVAL2011Q2 SDK? I went to the RR website, seems I can only find 365 SDK? Thanks.
You can fin at the RidgeRun download center web page the following information:
For DM368 you can use the same evaluation SDK for DM365 Leopard, you will get the same results, the only difference is the speed clock. If you want to get DM368 SDK demo, please let us know.
By "DM368 SDK demo", you mean, a pre-built image that can be installed to the nand and run the applications built-in from it?
For evaluation purposes, most people can complete their evaluation using the DM365 SDK. You can require the DM368 SDK from RidgeRun's website. At this time we are unable to support the hobbyist community with a DM368 evaluation SDK.
Hi, Todd, if possible, we can start the evaluation with a DM368 SDK without support. Where can it be downloaded? I went to RR's website many times and only saw DM365 EVAL SDK.
Please contact RidgeRun at firstname.lastname@example.org
Back to the topic. I have built the SDK, by doing a make build, got kernel uImage, u-boot , uBL, etc built, then tried to make the SD image by doing a "make sd_boot_recover device=/dev/sdb", where sdb is my SD card device. then got "make: *** No rule to make target `sd_boot_recover'. Stop.", "make help" did not give sd_boot_recover" option. Please advice.
RR SDK don't use those commands anymore, it appears that the guide that you were using was out of date, the guide has been updated now, please check:
Now that the bootloader of your board was updated by the Installer SD you can also use the SDK to install kernel and file system directly into the board without the need of using an SD card, all the instructions are available at:
Thanks. Will try that. Cheers!
