nrf: ld: add ARM.exidx to output image2020-05-27T03:28:48+00:00Sean Crosssean@xobs.io2020-05-20T12:06:36+00:00urn:sha1:17ef2df2cacc234e98f729ab60c3af9ec02dd08d
With the WDT changes, building Circuit Python results in the following error:
/opt/gcc-arm-none-eabi-9-2019-q4-major/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld: section .ARM.exidx LMA [00000000000621c8,00000000000621cf] overlaps section .data LMA [00000000000621c8,0000000000062383]
This is because unwinding data is getting generated, but has nowhere to go.
Re-enable this data in the linker script so it is saved.

nrf: linker: add a new .uninitialized section2020-05-18T03:52:17+00:00Sean Crosssean@xobs.io2020-05-18T03:43:21+00:00urn:sha1:f002c784c0af2272b1fdd5430379bc7775d89743
This section immediately follows the .bss section, and is designed to
contain uninitialized variables that should persist across reboots.
The section is placed directly after .bss, under the theory that the
size of Circuit Python's .bss + .data is bigger than the bootloader's
.bss + .data, so there is less likely to be a conflict.

nrf: add support for nrf528332020-04-21T04:29:56+00:00Sean Crosssean@xobs.io2020-04-17T02:35:33+00:00urn:sha1:3ed5b87b8fea218c0485282ed1cf9fdf5a6f687f
This adds preliminary support for the nRF52833, which is a variant of
the nRF52840 with half the RAM, half the flash, and fewer peripherals.

PacketBuffer facilitates packet oriented BLE protocols such as BLE
MIDI and the Apple Media Service.
This also adds PHY, MTU and connection event extension negotiation
to speed up data transfer when possible.
