Where do I get the Firmware updates for MK20

Hello,

does anybody know where firmware updates for MK20 are provided?

Thanks, railwaycoder

Question relating to:

Last updated: 27 Aug 2020
BLE Nano is the smallest Bluetooth 4.1 Low Energy (BLE) development board in the market. The core is Nordic nRF51822 (an ARM Cortex-M0 SoC plus BLE capability) running at 16MHz …

The last change to the CMSIS-DAP repo (https://github.com/Cheong2K/CMSIS-DAP) for the RedBearLab MK20 firmware is in was in late July, so I doubt there are any updates to shipping BLE Nanos. I don't have a Nano, but I'm using a modified version of this fork on an MCHCK MK20 board. Flashing with USB-MSD is spotty with this firmware, but recent pyOCD works great.
