After NVIC_SystemReset() is the SRAM content retained?
I want to write some magic value to SRAM and make NVIC_SystemReset() then in my bootloader check this value to go in boot mode.

I have found:
https://www.lpcware.com/content/faq/after-software-reset-wd-reset-bod-reset-sram-content-retained

I just want to check only one variable in SRAM. I use for that SRAM section not used in software. In link "LPC1769 - keep settings after restart of program" there is example with variable retained after software reset.

So is it possible or not?
