Firmware begins!

We have started working on the E370 firmware, running on the ARM processor.

The very first thing is to write a bootloader from the mSD card. This allows for a field upgrade of the entire E370 OS to fix bugs or to add new features. The new file will be downloaded off our website, saved to the mSD card and when the E370 is turned on, the card is scanned.

The whole bootloader code is restricted to a special 32K region in the FLASH memory, so the graphics and text are a bit 'crude', but as you can see we are writing to the new TFT screen using SPI signalling. You gotta start somewhere! 

IT'S ALIVE!
