Bootloader with support for firmware updates from SD-cards

Question asked by Frank Voorburg on May 29, 2013
The OpenBLT bootloader now supports making firmware updates from a Motorola S-record file stored on an SD-card. It uses Chan's FATFS module for file access.

Firmware updates are now as easy as: (1) store S-Record on SD-card, (2) insert SD-card in slot on microcontroller board, and (3) press reset. Everything else is done automatically.

The OpenBLT download package contains demos that support firmware updates from SD-card for the following boards:

  • Olimex STM32-E407
  • Olimex STM32-P103
  • TI EK-LM3S6965
