How do I prevent a SD cardf rom automatic flashing my embedded flash

Hi,

How do you prevent an sd card form automatic flashing my embedded flash (why is this possible in the first place, is pushing a button that hard)
Because I like my data on the embedded flash and i want to keep it there. it’s nice data.

Hope you can help.

RTFM. Use the right image.

Can you please point me too the (technical) documentation where the mechanism is described.
Thanks,

You unplug the SD card. If the SD card has a flasher image on it, it automatically loads it and flashes the eMMC. That is the way it is designed to work.
