From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I have been banging my head against the desk over this. I can use u-boot on the SD card to boot alpine off a flash drive. I cannot get the entire thing running off SD card though. It keeps doing this. What am I missing?

Ah, so it's the boot order and why it can't mount the volume.

The wiki seems to suggest a process to boot reliably from SD card, but I'm seeing a lot of posts with the same issues. https://wiki.friendlyelec.com/wiki/index.php/NanoPi_R5C#Install_OS

I'm using the R4S, it's a different model with a different SoC. I know there used to be a weird bug on this board regarding SD cards that was supposedly fixed in 2022 (https://kohlschuetter.github.io/blog/posts/2022/10/28/linux-nanopi-r4s/)

The other option here seems to be using uboot to boot your SD card: https://docs.u-boot.org/en/latest/usage/partitions.html

Since you know you can boot it via USB, you can just tell it to then boot from your SD Card instead of relying on the r4s to boot it. Docs say it's possible to flash to the eMMC as well https://wiki.friendlyelec.com/wiki/index.php/NanoPi_R4S#eMMC_Boot

u-boot loads off the SD card because there is nowhere else to put it on this board. I want to put alpine there too. Alpine and u-boot can be on the same card but alpine wont finish loading unless it is being loaded from the USB port.
