Thank you for your help. So far so good, it seemed to work.
Here are my steps loading the boot loader.
Will continue with the app later. My plan is to build the blemesh app from
Nimble on this board.
pip3 install click cryptography
newt new NewtBLE
cd NewtBLE/
add external repositories to project.yml
repository.juullabs-oss-mcuboot:
type: github
vers: 1-latest
user: JuulLabs-OSS
repo: mcuboot
Bootloader
newt target create da1469x_boot
newt target set da1469x_boot app=@mcuboot/boot/mynewt
newt target set da1469x_boot
bsp=@apache-mynewt-core/hw/bsp/dialog_da1469x-dk-pro
newt target set da1469x_boot build_profile=optimized
newt target create da1469x_flash_loader
newt garget set da1469x_flash_loader
app=@apache-mynewt-core/apps/flash_loader
newt target set da1469x_flash_loader
bsp=@apache-mynewt-core/hw/bsp/dialog_da1469x-dk-pro
newt target set da1469x_flash_loader build_profile=optimized
newt target set da1469x_flash_loader
syscfg=FLASH_LOADER_DL_SZ=0x10000:RAM_RESIDENT=1
newt install
newt build da1469x_boot
newt build da1469x_flash_loader
newt load da1469x_boot
Loading bootloader
