Need Help Recovering Manjaro /boot Contents on Pinebook Pro

[calinb]

While (intending to) backup files before installing Tow-Boot, I accidentally deleted all the files in my boot partition on my NVMe SSD. The root partition is fine.

Afterwards, I installed a fresh Manjaro image to my eMMC and I am currently booting it. I suspect that my NVMe root partition contains everything I need to restore /boot on the NVMe. For example, I have /var/cache/pacman/pkg/linux-6.25-1-aarch64.pkg.tar.zst and all my other package archives.

Can I run pacman from my eMMC system and tell it to install the needed package(s) from my NVMe drive onto the boot partition of my NVMe drive?
Perhaps I can simply umount the eMMC /boot partition, mount the NVMe boot partition in its place and then open a terminal in on the NVMe (/run/media…/var/cache/pacman/pkg/) folder and type "pacman -U <package.zst> but I also suspect a chroot to the NVMe system will be necessary.

What packages do I need to install? Maybe all I need to do is re-install the kernel under chroot and it will build a new initramfs-linux.img, etc.

Thanks so much for any help with the process.

P.S. Unrelated but why does Tow-Boot say

Code:

WARNING: Bad CRC. Using default environment.

during boot.

I recently installed Tow-Boot to my SPI to replace u-boot installed on various other drives at various times.
