Hello,
I am looking for a how-to / walk-through for writing a custom bootloader for STM32. I need my device to bootload from attached SPI flash, so I can't use the built-in bootloader. So far I have been unable to find information about how to do this -- can anyone send a pointer to a how-to? (I am using uVision 4).
Thanks, -David Merrill
AN2557: STM32F10x in-application programming using the USART
"The purpose of this application note is to provide general guidelines for creating an IAP application... The STM32F10x microcontroller can run user-specific firmware to perform IAP of the microcontroller-embedded Flash memory. This feature allows the use of any type of communication protocol for the reprogramming process (such as CAN, USART, USB). USART is the example used in this application note."
