I‘ve got an RaspberryPi 4 2GB.
I want to control an self made cam slider.
With Flask I want to host a web site with the control panel.
When Flask is started there is no network conectivity on wlan0 and eth0.
In addition to that the CPU load is 90-92%.
After stopping Flask the CPU load is still 50%.
I figured out the process systemd-journald is responsible for that heavy CPU usage.
The log is full of the following error:
Code: Select all
raspberrypi kernel: brcmfmac: brcmf_sdio_htclk: HT Avail request error: -110https://github.com/raspberrypi/firmware/issues/1289
But the downgrade to 4.19.86 wasn‘t the solution. With the newest version the same problem appears.
Any suggestions?
