Dmesg error

I'm not sure if this related to this mod.

After SPI flashed, I noticed Dmesg show this:

[ 0.000000] [Firmware Bug]: Kernel image misaligned at boot, please fix your bootloader!

Pinebook Pro just boots OK, same error after DD idbloader.img and u-boot.itb to eMMC.

Issues with Manjaro kernel 5.8.1

Hi,
I have used your v2020.07-1 flashed to SPI with Manjaro kernel 5.7.10 and everything have been working fine. I have upgraded to Manjaro kernel 5.8.1 and now I can not boot from nvme. I get to shell and can see nvme is not discovered with blkid. When I revert back to 5.7.10 it boot fine again.

I tried to boot 5.8.1 from emmc and root on nvme, and that boot fine. Can this be same issue addressed in patch0007-address-NVMe-instability.patch?

Unable to use dd to write spiflash.bin

I'm using Manjaro, kernel 5.8.6-1-MANJARO-ARM.
Following the below instructions copied from https://github.com/pcm720/u-boot-build-scripts/releases/tag/v2020.07-1:

Writing to SPI Flash (Manjaro):
# flash_erase /dev/mtd0 0 0
# dd if=spiflash.bin of=/dev/mtd0

I get:

$ sudo flash_erase /dev/mtd0 0 0
Erasing 4 Kibyte @ fff000 -- 100 % complete
$ sudo dd if=spiflash.bin of=/dev/mtd0
dd: writing to '/dev/mtd0': Connection timed out
1+0 records in
0+0 records out
0 bytes copied, 0.202538 s, 0.0 kB/s

Not sure why it didn't work for me. Instead, I used (after flash_erase):

sudo nandwrite -p /dev/mtd0 spiflash.bin

And that seemed to work. Is there a reason to use dd instead of nandwrite?
