major environment mishap on NSA320

Hello,
in the process of tinkering with the environment of me NSA 320, i did a stupid thing:
i had a good serial connection to the box, and copied the output of "env print" to a textfile(2018-01-18_env_save.txt) on the NSA320.
This was meant to have a backup, in case i mess things up.
But when i did

sudo fw_setenv --script 2018-01-18_env_save.txt

it wrote all env lines in the wrong form key=value, not in the form "env set key value"(without the equal sign).


And then, after i painfully recreated every single line with

env set key value

and doublechecked the freshly typed env with the stored one via diff, i rebooted the NSA.
to my suprise, it didn't boot, and the env looked like:

To make a long story short, instead of restoring the former state of the env i made it worse.
Right now, the NSA does not boot, goes into blinking orange quite fast(maybe the led_error=orange line in the env?), and gives no life signs at the serial console.
I also checked the cabeling, it does not show anything anymore.
What did i do wrong?
Is there a way to revive the NSA?
I have another NSA320 at hand, and also a tftp-server, that i could use to boot the NSA. But i think i first want to regain access and response via serial port.
Will it accept a bootfile via serial?

2 Pieces NSA320 , u-boot 2016.05, debian 4.12.1, Several Mac and Linux boxes connected.
More into soldering than programming. Location:Hildesheim, Germany

Yes. Use UART booting with kwboot as mentioned in the u-boot release thread:
https://forum.doozan.com/read.php?3,12381

Quote

UART Booting: If possible, try to test this boot image with UART booting before flashing to NAND. See davygravy's UART booting using kwboot instruction here in this thread. The latest u-boot image released here should be used for UART booting, if your box is the type that supports it (these do not: Dockstar, Pogo E02, iConnect).
