 |
|
...but, they're a block...?
I'm trying to set up my first Gentoo instance on a RaspberryPi 4 machine. It will need to do WiFi.
At: https://wiki.gentoo.org/wiki/Raspberry_Pi4_64_Bit_Install#WiFi I read:
| Quote: | WiFi needs three firmware files from in /lib/firmware/brcm/:
brcmfmac43455-sdio.bin
brcmfmac43455-sdio.clm_blob
brcmfmac43455-sdio.txt |
[...]
| Quote: | | These files, including the Pi 4 version of above file, are found in sys-firmware/raspberrypi-wifi-ucode, to install it you'll also need to install sys-kernel/linux-firmware with the savedconfig USE flag |
So, let's do: | Code: | | # emerge -auvb linux-firmware raspberrypi-wifi-ucode |
...nope:
| Code: | Total: 2 packages (2 new), Size of downloads: 363156 KiB
Conflict: 2 blocks (2 unsatisfied)
* Error: The above package list contains packages which cannot be
* installed at the same time on the same system.
(sys-kernel/linux-firmware-20240410:0/0::gentoo, ebuild scheduled for merge) pulled in by
linux-firmware
(sys-firmware/raspberrypi-wifi-ucode-20221012.1_p1:0/0::gentoo, ebuild scheduled for merge) pulled in by
raspberrypi-wifi-ucode |
Maybe irrelevant but just in case: I did add, in 'make.conf': | Code: | # because, Broadcom
ACCEPT_LICENSE="*" |
...figuring, I'll fix that to be more specific than "*" once I have this fixed; my guess is it doesn't matter but who knows...
Might the HowTo that I'm reading is out of date, maybe? |

It's in | Quote: | | also need to install sys-kernel/linux-firmware with the savedconfig USE flag |
When you enable savedconfig for the sys-kernel/linux-firmware package, it allows you to only install the firmware you want by using these instructions.
If you set savedconfig then install sys-kernel/linux-firmware first, then try to install sys-kernel/raspberrypi-wifi-ucode the ebuild will spit out a list of the files you need to remove via the config file. |

Ah, thanks! I was misreading that line, now I understand the need to build those in sequence.
Next, I'm realizing what a mistake it's been to have a Pi VM build stuff. This is getting old. Time for me to learn how to make arm64 builds on the Real Computer... |

twork,
| Code: |
roy@neddy_static ~ $ ls /lib/firmware/brcm/brcmfmac43455-sdio.bin
/lib/firmware/brcm/brcmfmac43455-sdio.bin
roy@neddy_static ~ $ ls /lib/firmware/brcm/brcmfmac43455-sdio.clm_blob
/lib/firmware/brcm/brcmfmac43455-sdio.clm_blob
roy@neddy_static ~ $ ls /lib/firmware/brcm/brcmfmac43455-sdio.txt
ls: cannot access '/lib/firmware/brcm/brcmfmac43455-sdio.txt': No such file or directory |
Only brcmfmac43455-sdio.txt is missing from linux-firmware now. At least, by name.
The other files are symbolic links to .../cypress/cyfmac...

OK thanks, that's (part of, sort of) what has been confusing me. In:
https://wiki.gentoo.org/wiki/Raspberry_Pi_Install_Guide#WIFI
...there are explicit references to the Pi5, and some explicit "in all cases" elsewhere, so I checked the Pi4 page -- I know, not as up to date, but still, Different; I can't tell when I'm guessing and when I'm guessing wrong.
I should just go plug this into hardware and see what happens. It's a Pi, FFS, WCPGW. Practice the Way, all that, wat ho. |

twork,
The Pi3, 4 and 5 wifi firmware are all different.
The https://wiki.gentoo.org/wiki/Raspberry_Pi_Install_Guide#WIFI was written around the Pi5. That section really needs to be moved into the Pi5 specific section and the wifi part from the Pi4 guide updated and moved over to the Pi4 part, which in currently empty. Bluetooth is similar.
