Subject: [Zephyr-users] UART flash

Hi,
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.

Also in the future we'd like to map firmware update to HCI so that it's all integrated.

Regards,

Carles
