How to flash to SD #1

Open TopperBG opened 6 years ago

TopperBG commented 6 years ago

Once finished, you will find u-boot.bin, zImage, and rootfs.tar.gz in buildroot/output/images you can now flash these to your SD card.

How to flash it - in one boot partition, in two partition (one boot with u-boot.bin & zImage, second rootfs with excrated rootfs.tar.gz) or just place files in fat32? ext4? partition

Please advice Thank you

I believe what you need is this, it creates the SD Card with the bootloader in the correct place, if you need to use your own, the should got in the prebuilt directory, you can look at the fusing.sh script for what happens.

Yeah, already use it, also my script (very similar) but have a bad feeling like I'm not change the u-boot or other content ... Thank you, will continue to dig.

Hi TopperBG -- If you are using the NanoPi 1, you may want to try nanoboot: https://github.com/ARMWorks/NanoPi-nanoboot

It uses a FAT filesystem for /boot and ext4 for /. Its configurable with a simple text file like the RasberryPi's bootloader.

Best regards, Jeff Kent

I'm using NanoPi Air but there is no big difference.

jkent commented 6 years ago

There is a HUGE difference between the NanoPi and the NanoPi Neo Air. The NanoPi has a Samsung S3C2451 and the NanoPi Neo Air is an Allwinner H3.

These are the tools you need: https://github.com/friendlyarm/h3_lichee/tree/master/fa_tools
