Version: bookworm

I know it is a little out there, but when I try to install Bookworm via netboot installer on my Nvidia Tegra K1 dev board, it hangs in "Starting kernel". I've copied the files from here: https://deb.debian.org/debian/dists/bookworm/main/installer-armhf/current/images/netboot/ to my TFTP server location on my laptop.

 I load them with the following commands, and it seems fine.
tftpboot ${kernel_addr_r} jetson-tk1/vmlinuz tftpboot ${fdt_addr_r} jetson-tk1/tegra124-jetson-tk1.dtb
tftpboot ${ramdisk_addr_r} jetson-tk1/initrd.gz

Subsequently I start the installer with:
bootz ${kernel_addr_r} ${ramdisk_addr_r}:${filesize} ${fdt_addr_r}

It starts, but hangs on the text "Starting kernel". I don't know how to get any log messages. I am installing it via serial interface. The files are retrieved via ethernet lan. When I do the same with Bullseye: https://deb.debian.org/debian/dists/bullseye/main/installer-armhf/current/images/netboot/
the installer starts successfully.

I am running the latest stable u-boot, armhf 2023 https://packages.debian.org/bookworm/u-boot-tegra

My device is Nvidia Tegra K1, Arm7, 32 bit. https://wiki.debian.org/InstallingDebianOn/NVIDIA/Jetson-TK1 http://neelus.eu5.net/nvidia-tegra-k1/ Thanks,
