Hello,

I'm trying to figure out the production process of my product and I cannot understand how the SYSCFG_MEMRMP bits work.

Is it possible (and how) to put the boot pins physically (via pu/pd res) to boot the builtin bootloader, use this bootloader to program my own bootloader, and add some code in my own bootloader to disable the built-in bootloader (and additionnaly enter ReadOut Protection, at least level 1) ?

This way we could plug empty boards to USART 1 (I use it for PC communication too in the application), and do the whole programming process without the need for an another programming port.

Thomas.
