The "linux" command still produces the "file not found" error message.
It looks like GRUB is found and started. But then somethig goes wrong.
To check for bad USB stick, I downloaded debian-12.8.0-amd64-DVD-1.iso and built
a new 12.8 USB installation stick using command
dd if=debian-12.8.0-and64-DVD-1.iso of=/dev/sdj1 bs=4M && sync
I tried booting this and got to a GRUB command line. This time ls -l reports
that (hd0) has "no known filesystem detected", although (hd0,msdos1) reports
"File system type ISO9660. Label Debian 12.8.0 amd64 1".
It seems to me that the GRUB command line comes from the T5820 BIOS and not from
the USB stick. To test this I restarted and hit F2 to get to the BIOS Setup.
This reports Boot sequence: 1) debian, 2) UEFI SMI USB DISK 110 (Windows Boot
manager is excluded). The boot option is UEFI. It's the mention of "debian" by
the BIOS itself which says to me that the T5820 contains a GRUB.
