Intel yocto images?

Jump to solution

Hi,

I have problems understanding yocto images for Galileo available at Intel.

I do not have problems when following the step-by-step guides for using Arduino or XDK IDEs, but I find confusing:

a) Right now, there are several images available for download:

a.1) http://www.intel.com/content/www/us/en/support/boards-and-kits/intel-galileo-boards/000005614.html Software Downloads for Intel® Galileo Gen 2 Board

a.2) https://software.intel.com/sites/landingpage/iotdk/board-boot-image.html IoT Download - Board Boot Image

a.3) https://software.intel.com/en-us/iot/hardware/galileo/downloads https://software.intel.com/en-us/iot/hardware/galileo/downloads

 

a.1) Seems to be only for Galileo Gen 2 card, and it has a 48MB image, is it the so called uclibc based image?

a.2) ... maybe it's an old version of the so called eglibc based image?

a.3) Seems to be for every Galileo (Gen 1&2), is it the so called eglibc based image?

b) Why two versions and strong size difference of images?

c) Some time ago I was warned about

This page https://software.intel.com/en-us/iot/hardware/galileo/downloads IoT - Intel® Galileo Board Download | Intel® Developer Zone says : "The uClibc image is no longer supported, but offered here for your convenience." Although what that means is up to interpretation.

now, that page does not include that statement and there is no explanation about the change/update, can any body explain it?

thanks in advance,

Fernando.

Hi,

 

 

Check out our answers below:

 

 

A1. This is the uclibc image but not necessarily for Gen 2 only, you can also use this image in the Galileo Gen 1.

 

A2. This is an old version of the eglibc image.

 

A3. This is also an eglibc image. Can be used in both versions of the Galileo board and is the newer version.

 

 

b. The user is supposed to choose the uclibc or eglibc image depending on the requirements of the project. For example, the uclibc image is a lighter image that's recommended if you're going to use the Arduino IDE. The sketches compiled in the IDE are compiled in uclibc. The eglibc image is used for more complex applications. This image has the libraries to use Eclipse or the XDK. This, and other features of this image is what makes the difference in size.

 

 

c. About the removal of that disclaimer, the images themselves have not changed. Both images are available for download so that users can choose which image to choose based on the requirements and the explanation of b.

 

 

Let me know if this answered your questions.

Thanks for your reply, mostly explains everything...

So the disclaimer was either erroneous or any other thing changed?

No, there are no changes in the uclibc image. If users in the community are using the uclibc or eglibc image we'd still provide suggestions and help out as much as we can, regardless of the image used. However the latest image is the eglibc image, which is the one the website says it's supported.

It's not completely clear...

" uclibc or eglibc image we'd still provide suggestions and help out as much as we can"

and

(eglibc) " which is the one the website says it's supported"

but never mind, it's good to know you are still giving your support.

And thank you very much,

Fernando.
