How much flash and RAM is required for the MCU bootloader?
Thanks in advance
Solved! Go to Solution.
It really depends on the features you select and optimization level too.
See https://mcuoneclipse.com/2018/03/03/flash-resident-usb-hid-bootloader-with-the-nxp-kinetis-k22-micro... where it shows different configurations.

Thank you very much.
I only wanted to have a general idea of required size.
By the way, I follow your blog and I find it very useful to learn MCUXpresso tricks.
Thank you :-).
To give you an idea:
My bootloader (McuBoot) for the K22 supporting USB HID needs around 18KB Flash and 8 KB RAM (-Os)
