How to build an image for the SIMATIC IOT2000?

Hi bergmanu,

I've tried to build the image following your HowTo, but I'm fail on task 4367 of 4369 :-/

I've been resated the bitbake for several times due some network issues. The origin error is in File: '/home/projects/iot2000/poky/meta/classes/license.bbclass', lineno: 33, function: write_deploy_manifest
and the error is

Exception: IOError: [Errno 2] No such file or directory: '/home/projects/iot2000/iot2000-build/tmp/deploy/licenses/iot2000-example-image-iot2000-20161121095438/image_license.manifest'

Checking fhe build/tmp/deploy/licences direcory shows that there is a directory iot2000-example-image-iot2000-20161118115245, but it contains a different timestamp. So, I assume that I must force to redo one of the 4367 task in order to build a actual directory. But which one? Or can I pass this directory to Bitbake for using instead?

Thanks Olaf

Hello bergmanu,

thanks for your reply, I will try this next time. Meanwhile I found a pretty straight forward solution. I let bitbake list the environments via

bitbake -e iot2000-example-image

and, to me, it looks like, that bitbake always creates a new timestamp each time it runs:

DATETIME = "${DATE}${TIME}"

So, I replaced "${DATE}${TIME}" of the line above with the timestamp from the previous build and bitbake completes without errors. Perhaps it’s not a good idea, to use the timestamp within the license directory name.

Best regards

Hello,

I was able to build the Yocto image. I created a guide to add a little more detail explaining the process here:

https://www.dmcinfo.com/latest-thinking/blog/id/9395/creating-a-linux-image-for-the-siemens-iot2000-series

I would appreciate any feedback you have and would be happy to answer any questions.

Hi Andrew,

I suggest

git cherry-pick b4df9df462

for fixing the error. Seems easier and "safer" ;) But nice description for adding a layer.

DevGuy, 

Thanks for checking it out and thanks for the feedback . I'd like to discuss further whether cherry-pick makes more sense. I'm going to PM you to keep this thread clean. 

Hi, I've tried to build the example image following this https://github.com/siemens/meta-iot2000/tree/master/meta-iot2000-example but keep getting this error:
