Re: Moving Linux Kernel to 5.4

I'm also seeing the CPU clock reported stuck at 200MHz, and these errors in dmesg; [ 1.003326] raspberrypi-clk raspberrypi-clk: Missing firmware node [ 1.003435] raspberrypi-clk: probe of raspberrypi-clk failed with error -2 This is on a 2Gb Pi4 with fully-updated Raspbian and a 64-bit kernel.

Re: Raspbian buster bluetooth failure after 2019.09.16 update

It seems this issue has re-surfaced with the latest firmware update (firmware-brcm80211 1:20190114-1+rpt5). My Apple keyboard pairs OK but the Pi won't respond. btmon shows the keyboard continually connecting and timing out - sorry this board won't let me attach the log file. Reverting to the +rpt4 ...

Re: Troublesome TCP SYNs

I've been seeing these for the last week. The source IPs (presumably spoofed) belong to hosting and cloud providers, and each IP sends roughly one SYN per minute. The largest number of different IPs I've seen at one time is 384. This article suggests a way of automating countermeasures, though facin...

Re: Raspbian buster bluetooth failure after 2019.09.16 update

@PhilE many thanks for the reply.

Replacing the three brcmfmac43455* files in /lib/firmware/brcm with the previous versions fixes bluetooth keyboard on my test SD - it wasn't necessary to downgrade the bluetooth firmware.

Thanks again.

Re: Raspbian buster bluetooth failure after 2019.09.16 update

I built a fresh SD card from the current Raspbian image (2019.09.24); the bluetooth keyboard worked. I then upgraded the packages one-by-one to the latest version, testing the bt keyboard each time. The package which 'broke' the keyboard was firmware-brcm80211. OK this may not be a valid test, as th...

Re: Bluetooth Devices keep disconnecting

Trying to narrow down the problem... I got my Pi4 on 18/9 and bluetooth was working fine for some time after. Now 'bluez' and the userland bluetooth software haven't been updated in that time, so the problem must presumably lie in the kernel or firmware. Unfortunately I've run 'rpi-update' a couple ...

Same problem on a fully-updated Pi4 when trying to use an Apple keyboard. Monitoring the bluetooth status with btmon, the initial pairing works OK, then there is a timeout after 20 seconds and pairing is lost. At this point the bluetoothd process goes to 100% CPU. 30 seconds later the Pi re-tries pa...

Yes, my CPC / Farnell 'Wi-Pi' dongle is seeing the same effect from a newly downloaded Rasbian. The fix mentioned in http://www.raspberrypi.org/phpBB3/viewt ... 28&t=44897 seems to fix matters, though I only made the change an hour ago.

Many thanks for the comments. I've connected my power feed to the 5v and 0v pins of the USB sockets (with a beefy 'idiot diode' upstream to guard against connecting the wrong way round) and everything is working well.
