Bootloader for STM32, XMC, HCS12 and other microcontroller targets.
OpenBLT is mostly used as an STM32 bootloader, due to the popularity of STM32 microcontrollers. However, the bootloader’s architecture is such that it can work with any microcontroller and use any type of communication interface to perform firmware updates.
fxload utility from linux-hotplug project updated for the FX3
This is a branch from the fxload project, originally part of the linux-hotplug SourceForge project which seems to be abandoned. This branch incorporates the patch from Steven J. Magnani that adds support for Cypress FX3 USB 3.0 endpoint to the fxload utility. It has been tested on Ubuntu 12.04 with the FX3 development kit (part number CYUSB3KIT-001). Oddly, as of January 2013 Cypress doesn't include this utility with its (open source) Linux SDK but requires developers to purchase a copy...
SDBoot is a complete bootloader solution (MCU side and PC side), free, with source code for AVR MCU chip. It features a checksumed protocol for safe programming.
The Affordable BIOS Restoration Tool provides VHDL and C code to recover from failed BIOS upgrades using affordable CPLD's. EEPROM's and Flash chips can be restored with this flash programmer. Interfaces for DIP and tsop packages are being developed.
A Protected mode microkernel for the x86 system.
With features like memory management, multitasking and protection will be included in the kernel, the rest will be added as drivers/software.
