nrf52 and PCA10040 blinks but doesn't shout (no radio)
Hi,
I can't get the bletiny or the bleprph or the nimble walkthru to work,
although the blinky sample does.
macOS: 10.11.4
board: nrf52 on a PCA10040
Please note that in order to get the bleprph app to compile in my new
project I had to perform a copy and monkey patch the app name as the
pkg.yml was missing from the bleprph folder, e.g.:
cp repos/apache-mynewt-core/apps/bletiny/pkg.yml
repos/apache-mynewt-core/apps/bleprph/pkg.yml
nano repos/apache-mynewt-core/apps/bleprph/pkg.yml

Re: nrf52 and PCA10040 blinks but doesn't shout (no radio)
Posted by will sanfilippo <wi...@runtime.io>.
Hello:
The nrf52pdk cannot be used with the new nrf52dk which you are using (PCA 10040). It is not hard to fix; you just need to remove the CODE_RAM section from the linker script and adjust the total amount of RAM. We just got our nrf52dk boards and will have a bsp for it shortly (next week) but the changes are simple. I can send you an updated linker script if you like or you can make the changes locally. There are only three lines you should have to change:
1) Remove CODE_RAM from MEMORY sections.
2) Change RAM from 0x8000 to 0x10000 (since this has 64K).
3) Change CODE_RAM to RAM for bssnz section.
I am on the IRC so if you have issues let me know.
