La Frite AML-S805X-AC not booting and with UART message Firmware load fail!

I started using my La Frite AML-S805X-AC again. It has been dormant for a few month with no power.
After providing it with power it did not show any image on my monitor.
Curious way it did not boot I conneted my TTL232 to it and sag that it was stuck
in a loop, showing the following message over and over again, see below.

unfortunately it will not boot from usb.

I also provided it with power over USB_A-to-USB_A cable while holding the u-boot button. This only gave the following line with no other option and no image on my monitor.

Any help and suggestion would be much appriciated.

Where did you get the unit? The software on the SPI NOR was corrupted.

To be honest, I do not remember. It have been approximately over 1,5 year.

I never heard of SPI NOR, is there a way to bring it back to life?

What can I do to make it work again?
