Help with booting NSA310S - Linux Kernel 5.7.1 (no replies)

Hi,

First of all, thank you bodhi for your hard work for these devices :)

I have an old, unused NSA310S in my gardrobe so I decided to try to install Debian on it. I don't want to use a USB drive for this purpose, so want to install the rootfs on the HDD (plan is to create 3 partitions, ext2 sda1 for kernel, ext4 sda2 for rootfs and swap). Downloaded your last (5.7.1) kernel, put the uimage and a generated netinstaller uinitrd on an USB-drive (which has only one FAT partition) and set the uboot parameters like in this article:

Unfortunately it dont' start the uinitrd as when I try to boot I got this error message:

As I can understand it is an uboot env problem. My uboot env is (original uboot):

Do you have any idea what to change? :)

Thanks in advance!
