TI code vs, RidgeRun code, evm vs Leopardboard

Wesley Miller said:

Is the Ti build (kernel, DVDSK, gstreamer(?), PSP, etc.) meant only for the EVM.  It runs on Leopard but when it boots I see lots of errors and warnings about unneeded stuff, many tvp7002 retries, disabled clocks and modprobes that fail.

Should that happen?  Or do I have compile errors that I need to figure out?

Can you attach the boot log containing the errors that you notice?

I am not too familiar with Leopard board, but here are few top level comments:

1) If the kernel for EVM boots on Leopard, then the 2 boards should be quite similar

2) Since you see many errors during boot, they could be due to differences in the on-board devices or just their connectivity with the processor e.g. using different GPIO for reset, ...

3) Is there a kernel configuration defied for Leopard board? If so you may want to build kernel against this configuration.

4) Else, you can start with the configuration for the EVM and use "make menuconfig" to customize it for leopard. This customization can help you exclude the devices that don't exist on Leopard - and reduce the errors you would be noticing during boot.

5) Changes would be required in other layers (e.g. u-boot) as well.

BTW, which EVM platform are you referring here?

Wesley Miller said:

The long and short of this is that my management really does not want to touch RR code since there are all those fees and royalties involved.  Is that reasonable?  Are there other code development teams/projects that are GPL or best LGPL or Berkley/MIT/CPL?

This should be best addressed by the legal team of your company. You shouldn't be making decisions on public opinions.

Just to let you know Linux is GPLv2 and different software components on the user-side are licensed differently. The license information is included in corresponding packages.

Wes,

You would have to follow the steps as documented in the Leopard EVM documentation/website.

As I understand RR did the basic port for the TI platform and used TI EVM to validate it.  Leopard would have used the RR port as the base (and modified it to suite Leopard EVM) to test the kernel and other products on top of it.

Linux Kernel is GPL and hence there are no royalties as I understand it.  You can modify it and share the modification with others.

There would be a leopard EVM config as part of Linux kernel config you would have to compile the kernel using that if you are using Leopard EVM.

Sanjeev,

There are no files in /var/log on the LeopardBoaard i.e. in the NFS dir on the host PC).  Why?

Here is the output from the console:  (sorry for the long post)

There seems to be difference between the filesystem and the kernel version you are using...  You need to create the directory /lib/modules/2.6.32.17-davinci1 in your filesystem and ensure that modules corresponding to the kernel version you are using are added to this location. If you aren't using any modules, you should be able to safely ignore these warnings.

I still don't quite know why, but i fixed these by just creating the directory /lib/modules/2.6.32.17-davinci1.  On the next boot, several files were created there and I got a completely different set of happy messages (at this point, anyway).  I did not have to put any .ko's there!

 

One down!

Thanks,

Wes

 

Hi Wes,

I'm Diego Dompe, head of embedded software development at RidgeRun.

TI provides ports of the Linux kernels validated against the official EVMs for the platform, along with DVSDKs (meaning the software stack to use the HW accel codecs or the DSP). Most of that code is open source or royalty free (check the licenses, I'm not a lawyer). TI only provides software for their EVMs, other third-party boards like Leopard or Beagle rely on the community support.

RidgeRun is third party to TI and creates a product (RidgeRun SDK) that integrates the software components provided by TI into a coherent, structured and proved solution for developing products. You can achieve the same results that the RidgeRun SDK by putting together all the open source components yourself or using other tools like Arago/OE. Depending on your level of Linux expertise may find that is cheaper and easier to just buy a RidgeRun SDK instead of wasting your time focus on your tools instead of creating the value-add of your embedded product.

RidgeRun specially supports the LeopardBoard and has adapted TI software stack for the LeopardBoard itself (with sponsor from TI). RidgeRun offers an evaluation SDK that allow you to use the RidgeRun software included on the SDK for non-commercial proposes on the LeopardBoard hardware.

Since RidgeRun SDK uses open source software, these software is ruled by their respective licenses. This means that if you download a RidgeRun SDK for evaluation and you want to use the patches to the kernel that you found there, you are welcome to do so. RidgeRun SDK also includes software that belongs to RidgeRun and is licensed on different terms.

RidgeRun SDK is a product that you buy with a single upfront payment and have no hidden costs. I wonder where do you get the idea that RidgeRun SDK has any royalty associated with it?

Hopes it clears a bit the panorama. Let me know if you have any question.

Regards,

Diego
