The T1000-E ships with the Adafruit nRF52 Bootloader, you can find flashing instructions [Adafruit nRF52 Bootloader](@ref boards_common_adafruit-nrf52-bootloader) section.
DFU mode must be entered manually before flashing. Follow the SeeedStudio instructions to put the device in DFU mode, then run:
BOARD=seeedstudio-sensecap-t1000e make -C examples/basic/hello-world flash
@note Accessing the SWD pads requires opening the device enclosure. Overwriting the bootloader via SWD would make UF2 flashing unavailable and is not recommended for normal use.
By default, stdio uses UART_DEV(1) (P0.16/P0.17).
UART_DEV(0) is reserved for the GNSS module. Connect a USB-to-UART adapter
to P0.16 (TX) and P0.17 (RX) to access the terminal.
To use USB CDC ACM (virtual serial port over the existing USB cable) instead,
you can add USEMODULE+=stdio_cdc_acm to your application's Makefile or to
the compiler call:
USEMODULE=stdio_cdc_acm BOARD=seeedstudio-sensecap-t1000e make -C examples/basic/hello-world flash term
