Using nucleo board as offline programmer

Hi,

i'm wondering if there is an easy solution for using nucle board as field programmer over SWD interface. I would like to programm blank stm32 device directly from nucleo board using external flash or stm32 device content. It should be done over onboard STlink or from embaded stm32 device directly.

Does someone have an example to turning stm32 device to swd programmer, or turning the onboard Stlink as offline programmer?

    The ST-LINK device doesn't have enough space to carry your firmware.

    You might look at the complexity of open source SWD/JTAG tools and decide if you want to manage that, and have a NUCLEO-F767 type part which can carry 2MB of firmware and payload.

    Connecting high speed via a USART and using the System Loader on the target may be simpler to do.

    I believe Segger and other vendors have commercial grade standalone programmers
