We are using CM4 with CM4 IO Board. There is already an OS in the eMMC flash. We want to backup this OS.
How can we backup the existing OS from the eMMC flash ?
Latter we need to program the new OS into the eMMC. The programming eMMC procedure is know to us.
If we put the OS in the SD card through RPi Imager and insert the SD card, given that eMMC also has an OS, than how the RPi will boot, through eMMC or through SD card ?
