Subject: [Zephyr-users] UART flash
we're using Zephyr for providing the HCI for a NRF52 chip.
The example from samples/bluetooth/hci_uart is working very well.
However the flashing is done using jtag (the integrated Segger chip on
the PAC10040 dev board).
Is there an option in Zephyr to have a bootloader that would support
flashing firmware through UART?
Yes, MCUboot supports serial recovery to upload flash images, and it's the main open source bootloader for Zephyr.https://github.com/runtimeco/mcuboot
Also in the future we'd like to map firmware update to HCI so that it's all integrated.
