Support for the new nrf52 DK from nordic
Hello:
Just wanted to let folks know that we added support for the new nrf52 DK. The BSP is in hw/bsp/nrf52dk. If you have exisiting targets using either the nrf51dk or nrf52pdk it should be easy to copy them and replace the bsp with the nrf52dk:
newt target copy my_old_nrf52pdk_target my_new_nrf52dk_target
newt target set my_new_nrf52dk_target bsp=hw/bsp/nrf52dk
Aside from fixing a number of errata, one of the big fixes was that now it is possible to address all of the RAM as data ram. The nrf52 chips on the Preview Development kits could only access 32K of the 64K as data ram; the other 32K was code ram. This was not a big deal unless you want to DMA from memory; you can only use data ram.
Anyway, please give it a spin. If there are any issues please let me know.
Enjoy!

Hi Wayne,
As you suspected, the latest changes go into a development branch.
They'll be in the next release, but if you want to try them out ahead of
time, you can configure your project to download packages from the
development branch.
To use the development branch, change your project.yml as follows:
FROM:
repository.apache-mynewt-core:
type: github
vers: 0-latest
user: apache
repo: incubator-mynewt-core
TO:
repository.apache-mynewt-core:
type: github
vers: 0-dev
user: apache
repo: incubator-mynewt-core
(change the "vers" field).
Then upgrade your packages with "newt upgrade", e.g.,
[ccollins@iori:~/tmp/myproj]$ newt upgrade
apache-mynewt-core
Would you like to upgrade repository apache-mynewt-core from 0.7.9-none to 0.0.0-none ? [Yn] y
Naturally, this branch is quite unstable.
Chris

Hi,
Thanks or this.
Please could you let me know what else needs to be run / updated /
downloaded prior to those commands in order to update the repo and obtain
the bsp package?
I tried `newt upgrade` on an existing project and also tried creating a
project from scratch but there is no
repos/papache-mynewt-core/hw/bsp/nrf52dk folder
Do I need to move from using the release build of newt and switch to a dev
version ?
All the best
Wayne
