Code examples for STM32 in circuit programming

[CAnde.1]

Using a STM32L0538-DISCO as the host for a production programmer/tester for a small STM32-based device. Production floor has no place for a PC+STM32Link!

In part I chose this board because it already has dedicated SWCLK/SWDIO interface...but I'm not entirely sure how to use it to interface with D.U.T.'s built-in bootloader.

Could also use some pointers on best way to hold the (small) .hex file in memory in host memory prior to transfer...
