How to flash STM32F429 LQFP176 through USART during production? I have tried STM32 Flash Loader demonstration tool but it looks like STM32F429 with 2MB flash is not supported. Any other tool to flash this chip during mass production?

TIA

The underlying protocol is pretty simple, and source code for the Flash Loader Demonstrator is provided. There are also Open Source solutions. A coder with Windows/Linux experience should be able to build a solution in a couple of man days or less.

The loader could also push in code to RAM, and then use a more robust XMODEM/YMODEM transfer to complete the job if you're more familiar with those protocols. See also ST's IAP examples.

What's your budget for a commercial solutions, per station?

Segger has a number of JTAG/SWD based solutions. With USB there's DFU Manager.
