I’m having the same issue as discussed in that old topic thread and I tried with 3 different SD cards (3 different brands) and tried it with no keyboard/mouse and monitor disconnected and got the same error. I’m using the latest image from the main download site.
Has anyone found a solution? Does the errors make any sense?
Note: if I use a USB flash/thumb drive (regular USB drive) it boots up to the login screen, but not with a SDCards. With SDcards it goes into that never ending error loop.
It’s looking like a fault in whatever SD card reader or app you are using to write the cards.
SD cards can be cleared using a proprietary formatter: SDFormat It’s closed source, so difficult to know what additional steps it is performing. Most useful for new cards.
Rodney Peters, thank you for the Formatter tool. I’ll give it a try.
For some strange reason, it boots and works with a regular USB flash drive/pendrive/thumbdrive. I’ll stick to the USB drive until I get more time to play with the SD Cards again. I spent all day today with the SD Cards and I’m tired LOL . USB works with no issues for some reason .
Years since I used RPi, but ISTR that activating USB boot on them was a one-way street, that simultaneously removed SD from the boot order. That might have changed with the later RPi.
I’ve had minimal problems writing SD cards for nanopi, bananapi & cubitruck, via a variety of SD card readers, so I think your problem is with the SD card reader. Are you writing the card on a 64-bit computer ?
