Features which we did not test by ourselves an listed in this table are taken from
(1) the YouTube video maker Leepspvideo
and
from
(2) alaraajavamma from the Pine64 forum:
https://forum.pine64.org/showthread.php?tid=18639
(3) Booting from an SD card is possible with the Seeedstudio Ethernet Carrier Board with a a CM 4 without eMMC:
(4) Test of the MRIS
- We where not able to install Raspberry PiOS on the eMMC of the CM4 after our first attempts as described here:
- We where also not able to erase the eMMC of the CM4 as described here:
youtu.be/a0S-_lCMZu4
- We tried to boot Raspberry Pi OS from an usb-c plug with an SSD card in a reader, as described here:
youtu.be/a0S-_lCMZu4
- We flashed Raspberry Pi OS on an SD card in an SC card reader, but when we started up the Pi Pad 5, it did not boot up.
- The Pi Pad 5 did not show the the boot up command lines as in the mentioned video, eventually because we where not able to erase the eMMC of the CM4 as in the video. Is this required for booting up from usb-2?
- We tested the dip switches for boot and the second one next to it, we tested both positions, the Pi Pad 5 did not boot up.
(5) Test by MRIS
- We have instslled it and tested it on a Pi 4 and it worked.
- SSD installation can be found at leepspvideo.
- Samsung bar memory stick speed tests can be found at leepspvideo. These sticks are according to leepspvideo almost as fast as SSDs. But they are handier for mobile applications.
