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

[pcm720]

I tried it but this is the output:

dd: writing to '/dev/mtd0': No space left on device
8129+0 records in
8128+0 records out
4161536 bytes (4.2 MB, 4.0 MiB) copied, 12.889 s, 323 kB/s

I see in lsblk there is no mtd0 device, just this:

mtdblock0     31:0    0     4M  0 disk
mtdblock1     31:1    0    32K  0 disk
mtdblock2     31:2    0   256K  0 disk

So I am a little afraid to reboot now

@Wizzard was able to fix incomplete SPI flash using Rockchip's rkdeveloptool.
Since the first 4 Mbytes of SPI image contain only DDR initialization and SPI bootcode, device got stuck in Loader mode.
Connecting it with USB-C cable to PC and executing the following was enough to fix it:

Code:

rkdeveloptool wl 0 /path/to/spiflash.bin
