I need someone to write a bootloader for the Atmel SAMD21 and Atmel SAMD11 that allows new firmware programs to be loaded over the I2C bus. Source code must be written in C or C++, compilable using the GCC toolchain, with comments in english. Compiled code must be smaller than 2KB. I will need an example new firmware loading sketch, compilable in the Arduino 1.8 IDE, that demonstrates sending new firmware from a PC to a target device using an existing SAMD21 board as a programmer. Bossac support is not required. Program should verify the checksum of the loaded firmware block and provide an indication back to the loading code if the new firmware was successful.

Will program in C. I2C bootloader is great, can update anytime instead of just while starting up - would find the work interesting. Relevant Skills and Experience I have never written a bootloader but I have written OTA update programs and so I think I can make it. I do honest work and if I see any hiccup I'll inform pre-emptively (and no completion no pay) Proposed Milestones $500 USD - Job done! Additional Services Offered $500 USD - Need a cheap wifi device (2 $) on I2C bus to trigger an update over the air? Hit me up in chat ? :-)

I propose to write the firmware using direct register addressing (i.e. not using the ASF). I would be developing and testing on Linux. Relevant Skills and Experience Wrote a USB bootloader for an STM32 home-automation device. Used i2c in temperature/humidity sensors and EEPROMs. My experience on Arduino has been mainly with 3D printer firmware. Proposed Milestones $150 USD - Initial proof of concept - a basic protocol layered on I2C $150 USD - Loading of new firmware over bootloader $150 USD - Testing, documentation and makefile Additional Services Offered $5 USD - Access to a password-protected Git repository (over HTTPs - not SSH) with latest software.
