Unable to install Debian Bullseye because of missing wifi firmware
I am trying to install Debian Bullseye. I have Tow-Boot already installed to SPI.

From http://http.us.debian.org/debian/dists/b...rd-images/ I downloaded 'partition.img,gz' and 'firmware.pinebook-pro-rk3399.img.gz' and combined them as per the accompanying README:

zcat ~/firmware.pinebook-pro-rk3399.img.gz ~/partition.img.gz > ~/complete_image.img

I then used Disk Image Writer to write the resulting image to SD.

The PBP/Tow-Boot boots the installer and I get to select Location, Language, Locale and Keyboard. The installer then probes the networking hardware and reports:

Quote:[!] Detect network hardware
Some of your hardware needs non-free firmware files to operate. The firmware can be loaded from removable media such as a USB stick or floppy. The missing firmware files are:
If you have such media available now, insert it, and continue.
Load missing firmware from removable media? [Yes/No]

I assumed this firmware would have been in the firmware image I used to create the installer.

I searched online but couldn't find these files.

On an SD card with Debian installed with Daniel Thompson's installer (unfortunately not longer working) I found 2 brcm directories with the following files:
Notably there is no 'brcmfmac43456-sdio.pine64,pinebook-pro.bin', but there is a .txt file with the same name.

I copied all these files to a USB thumb drive (EXT4). Running the installer again and answering 'Yes' to the 'Load missing firmware from removable media?' question only results in the installer repeating the question. Selecting 'No' gets me to a list of drivers to choose from but none of the Broadcom drivers selectable work.

What am I doing wrong?
OK, what I have in my debian sd card is
brcm]$ ls -l

I got rid of everything that was not 43456, except for the link, so long ago I don't remember details
But, I won't use a distro that does not have 'good' sleep, very few do
Thank you for your reply wdt and apologies for my late one: It turns out I didn't subscribe to my own thread and didn't get an email notification of your post.

I am very happy with my PBP on Manjaro now, it's quite an upgrade from Debian 10. As I would like my system to be encrypted I think I'll try Debian 11 again at some point with the latest image files and hope this issue will have disappeared. I'll report back either way.
Copy the files in the attachment in /usr/lib/brcm/ and you will have WiFi 2.4GHz & 5GHz. They're from Armbian. Works for me.
