what about PI 4

[GeorgeRaven]

I have the same issue on pi 2,3,4. try using the camera twice, the second time goes through. Its not pretty but it works. (apologies if the spacing is incorrect)
$this->bbcode_second_pass_code('', '
import picamera
for _ in range(2):
try: # try to init camera _ times
cam = picamera.PiCamera()
cam.start_preview()
except picamera.exc.PiCameraMMALError:
print("warning: unable to start camera")

cam.whatever.you.want.to.do()
')

Looks like Pi 4 aarch64 bit kernel has matured very fast. Sakaki already released an 64bit gentoo image with working V3D, dual screen, an support for the complete 4GiB RAM.

Hello,
someone have also problems with pi4 and nfs with current kernel?

wondering because lsmod shows no output.
It looks like the kernel module nfsd is not loaded. Can someone help me solve this problem?

tx in advance

tx graysky,
$this->bbcode_second_pass_code('', '
pacman -S linux-raspberrypi4

solved the problem.

cheers

I'm unable to get any audio for almost a month now out of the pi4. This started soon after the pi4-specific kernel was made available. Is this happening to anyone else?

Hello, are there any news at the 64bit kernel front?

Hi,

The thread below talks about a new "rpi-eeprom" package for Pi4 for updating the firmware:

https://www.raspberrypi.org/forums/view ... 4#p1534285

https://github.com/raspberrypi/rpi-eeprom

Will this package eventually make it to ALARM for manual invocation, or might it be automated during pacman updates?

Thanks!

Hi.

Just stepped over this thread.

I outlined my 64-bit -rpi-kernel, -userland, -userland tools journey for the 3B+ over here: https://archlinuxarm.org/forum/viewtopic.php?f=65&t=13948&p=62340#p62340.
based on the 64bit-RPI3 package and the RPI git kernel.

Does anybody know if meanwhile somebody is working on a PI-4 64bit package ? mainline or RPI kernel?

Thx.
