I would like to be able to reprogram the Flash program on my STM32F103 chip via in-application programming.

Essentially be able to upgrade the firmware without JTAG or bootloader jumper.

I have the PM0075 Programming Manual. I have the source, stm32f10x_flash.<c,h>

I have enough RAM to hold the entire program to be flashed.

I have not seen any application notes or forum postings on performing this task.

Many years ago, I had to perform this task and a small amount of code was located in RAM and this code performed the flash erase and write, along with the reboot after write.

Is this still the process to use to reprogram the flash via an application?

    Going to need to polish up on your Google skills, because this kind of stuff is pretty frequently covered.
