This repo is a Mynewt playground meant for development of Ambiq Apollo 3 support. It pulls in my custom mynewt-core and mynewt-nimble forks located at t3zeng/mynewt-core and t3zeng/mynewt-nimble respectively. An Apollo3 EVB is required to run the targets in this repo.

Setting this repo up is very standard for a Mynewt repo. Run newt upgrade to pull in all of the necessary repos to run the applications.

The bootloader target is named my_blinky_boot. You may build it using newt build my_blinky_boot and load it using newt load my_blinky_boot. The Ambiq Apollo3 Secure Bootloader located at 0x0000 cannot be modified and the memory is protected all the way up until 0xc0000. The Secure Bootloader will run code starting at 0xc000 so mcuboot is placed at this address.

The main app used to validate Ambiq Apollo3 support on mynewt-core is called my_blinky. This app can test GPIOs, LEDs, I2C, SPI, UART and the ADC. There are also a couple of nimBLE apps brought into this repo to test Bluetooth. These are the bleprph and btshell example apps which can be run using the target ble_test_target. Currently I am switching between the apps by changing the app in target.yml.

The Apollo 3 work for mynewt-core is ready for review to go upstream into apache-mynewt-core so you can use the master branch of t3zeng/mynewt-core fork. The nimBLE stack is still a WIP so instead of using master branch in t3zeng/mynewt-nimble, use the branch tian-playground.
