Hi Bruce,
This is for adding rt-app, please let me know what you think.
For next patch, I will add schedtool_dl
Reading this more closely, can you split this into two patches ?
We need to review this in chunks, patch 1 for the rt-app (it
looks fine), and another for the image definition ?
oe-core already has core-image-rt and core-image-rt-sdk, so the
naming and content here will be a bit confusing. We should
determine where we want the image definition, and if we can
simply extend the oe-core ones versus introducing new ones.
Cheers,
Bruce

Insop
