wasp-reloader is a tool that is used to update to the latest version of the wasp-bootloader.

It is a application payload that, when executed, will replace the softdevice and bootloader with an updated version and then reboot into the new bootloader ready to receive a new payload.

Note: wasp-reloader is tested using the GNU-RM toolchain (9-2019-q4) from Arm.
