Hello everyone. It has been a while since my last post. Today, I will go over using DFU over USB on PocketBeagle 2. I will only be loading the firmware to RAM, since that should be the normal use case when doing Zephyr development. It is possible to do DFU to MMC or SD Card, […]
Hello everyone. It has been a while since my last post. Today, I will go over using MCUboot based serial OTA on BeagleConnect Freedom. Everything required has already been merged to upstream Zephyr now, so no special considerations should be required. Introduction BeagleConnect Freedom contains a simple bootloader in ROM, which boots the Zephyr application […]
Hello everyone. In this post, I will go over the setup I use when doing Linux Kernel development. I will be using PocketBeagle 2 in this post, but the same instructions should work with most other BeagleBoard.org Boards. Setup The first step is to fetch the kernel repo. I am going to use linux-next in […]
Hello everyone. It’s been a while since my last post. Instead of doing the normal weekly update, I have decided to try writing something a bit more in-depth. Recently, I have been successful in publishing BeagleBoard Rust Imager to Flathub. So I thought it might be best to go over the development and publishing process. […]
Hello everyone. A typical work week. Let’s go over everything. Fix MicroBlocks CI Recently, the MicroBlocks CI which builds microblocks dev and pilot branches have been failing. After a bit of testing, I found that a cmsis_6 zephyr module is now required by BeagleConnect Freedom. The CI was fixed by allowing the module in the […]
Hello everyone. I ended up skipping some weekly updates since there was not much to talk about. Maybe I should make this series a bi-weekly thing instead of weekly updates. Anyway, I will be going over things from all the missed weeks as well. Let’s get started. Zephyr Add MAIN domain USARTs for PocketBeagle 2 […]
Hello everyone. A typical work week. Let’s go over everything. Use extlinux in Armbian images Thanks to all the amazing work by Andrei Aldea, PocketBeagle 2 and other BeagleBoard.org boards support Armbian. By default, it seems Armbian uses the old uEnv.txt file to specify the boot entry. This is fine, but the newer extlinux.conf is […]
Hello everyone. A typical work week. Let’s go over everything. Zephyr support for PocketBeagle 2 PocketBeagle 2 is a single board computer with AM62xx soc, and the primary supported OS is Linux. We provide Debian-based images for the board, with initial support for Armbian. This is what most people will be using it with. However, […]
Hello everyone. A typical work week. Let’s go over everything. PocketBeagle 2 M4 GPIO Support Initial ZephyrRTOS support for PocketBeagle 2 M4 core was merged last week. This only included tested support for UART (RX: P2.05, TX: P2.07). It is possible to enable GPIO and I2C using overlays, but there are no examples at the […]
Hello everyone. A typical work week. Let’s go over everything. PocketBeagle 2 Examples More work went to make the PocketBeagle 2 Examples as educational as possible. The goal of the examples is to teach Linux APIs. Thus the examples try to use the kernel drivers for the different devices as much as possible. Make Blinky […]
