Long story short. I ordered 2 pack AML-S905X-CC (Le Potato) from the USA on Amazon UK for delivery to the UK. They arrived surprisingly quickly and hassle free. I bought them to run Pi-Hole. I currently have Pi-Hole running on a Raspberry Pi 3B, but wanted to run 2 instances, so unable to actually get hold of any Raspberry Pis for such a long time, checked out the alternatives and settled on the AML-S905X-CC (Le Potato).
I also got 2 new Official Raspberry Pi Power Supplies (5v 3A, 15.4 Watts). I downloaded Rapbian 11 Bullseye images (2022-09-22-raspbian-bullseye-arm64+aml-s905x-cc.img.xz and 2022-09-22-raspbian-bullseye-arm64-lite+aml-s905x-cc.img.xz) from the Libre Distro Server.
I ordered some SanDisk Extreme Pro 32 GB microSDHC Memory Cards and already had some SanDisk Ultra 32 GB Micro SDHD cards.
I followed the guidance to install the OS, formatted the SD Cards with SD Card Formatter, and imaged with Win32DiskImager. All of many attempts using different SD Cards and different Windows 11 PCs Wrote the image Successfully, but all immediately failed “Verification failed at Sector: 8192”.
So I imaged using RaspberryPiImager and it Verified OK.
I plug the SD card into the AML-S905X-CC (Le Potato), plug in Ethernet, Mouse and Keyboard and power up, but it does not boot successfully. It starts to boot, flashes up the following, and then reboots, and cycles round this continuously:
I try to build a bootable SD Card, using both AML-S905X-CC (Le Potato) and 5 different SanDisk SD cards, and different imaging software, including BalenaEtcher. I also tried with a Ubanto Image – Same Result!!! All results the same!
Wondering if it is a power issue, I unplug everything and try all sorts of different combinations, and eventually discover that it will boot properly on both boards, with all 5 SD Cards, IF the Keyboard is not plugged it, and will work fine if the keyboard is plugged in after boot has completed.
So I order an expensive 5v Power supply, an Anker USB C Charger, 726 Charger (Nano II 65W), which has oooodles of power and headroom. SAME Issue!!! So the problem is not power (Reading 5.01V on GPIO Header).
Now in my initial requirement, running Pi-Hole on a Headless board, it is not such a problem because it will work, but it means I will not be buying any more Libra SBCs unless I can fix this problem, and most applications will require a screen, keyboard and mouse as well as ethernet.
