U-Boot with direct NVMe boot support for eMMC/SPI Flash

[mamboman777]

Thanks for the encouragement.  Making a backup now.  

Just to be clear, you are saying I should follow instructions from this, right?  https://github.com/pcm720/u-boot-build-scripts

No, his earlier, rockchip-based uboot has this command for writing to SPI:

Code:

sudo dd if=spiflash.bin of=/dev/mtd0

Looking at the build script of the most recent (your link,) that spiflash.bin will be in your build folder.

Ok.  Still seeking clarification as I'd really like this to work the first time.  1. Download and extract from https://github.com/pcm720/u-boot-build-scripts
2. Run build.sh
3. then run "sudo dd if=spiflash.bin of=/dev/mtd0

If this is already documented someplace, I apologize, but could you please point me in the right direction.  

Thanks!

First of all, to build the U-Boot on x32/x64 PC, you'll need to install aarch64-linux-gnu-gcc cross-compiler.
Then, clone the repository with "git clone --recursive", this will also clone ATF and U-Boot repositories as submodules.
After that, just build the U-Boot with build.sh and write spiflash.bin to /dev/mtd0 via dd.

It's going to be a while, based off of the speed it looks like dejadup is running.  I've also got to make sure I have a working SD manjaro image before I get started.  That being said, I was planning on building and running this on my aarch64 PBP then flashing directly from there.  pcm720, are you saying that I should do something else?
