I just released my proof-of-concept dual bootloader(serial/mmc) for the arduino platform. Code is on github
Features:
- Just 2kb of flash, fits into normal 2kb bootblock of most atmega chips
- Serial (stk500v1) bootloader, compatible with avrdude and Arduino IDE
- Additional MMC bootloader, can read directly a intel .hex format file from an MMC/SD
- Includes all of ladyada’s fixes to the original bootloader
You might ask why?. I have quite a few arduino “in the field”. With this bootloader, I can simply drag a .hex file to an SD card, insert it in an SD shield, and field-upgrade my boards without additional hardware. But I can still use the serial/usb port to develop on the very same hardware.
Does someone out there want to try this with our data logger shield? Let us know if this works well! 🙂
