Hello
I have a question about writing hex file in MCU (STM32F767xx) without a development board.
I want to draw my PCB schematic but I am confused about which pins are used to flash the memory.
I tried finding it on the datasheet but with no luck. Could you please give me directions ?
Also, datasheet claims that on boot-up the MCU uses internal RC oscillator and switches to external one if software commands to. So can I exclude external oscillator and stick with that one only without any major issues ?
Solved! Go to Solution.

If you use SWD then pins SDIO SWCLK and optional SWO for debugging. Internal RC oscillator is less precise then external and more temperature depend.

OK thanks, got it. I would rather go with external oscillator then

pretty much what I was looking for
