My Raspberry: Pi 3B
a) I configured Raspberry to boot into USB:
echo program_usb_boot_mode=1 | sudo tee -a /boot/config.txt
Result: vcgencmd otp_dump | grep 17: 17:3020000a
b) I installed The Raspbian on the Kingston a400 (120Gb) SSD card using the "etcher"
c) I removed the SD card from the slot and booted into the Raspberry with my SSD card
d) Apparently, everything worked normal. The System expanded the partition inside the SSD and then opened the working screen.
However, the green LED (indicates read / write data on SD card) blinks the entire time the raspberry is turned on ... even when I am not working on it.
I notice that there is a constant exchange of information between the Raspberry and the SSD Card (even though it is only switched on without any activity).
This was not the case when I used the SD Card ...
What is going on?
Missing some configuration?
Is the process actually accessing the SSD and causing unnecessary wear on the card?
I am grateful for the attention and for any response to my topic.
