Re: Headers 4.19.75-v7l+ (Buster on PI3B+) and modules compile

New kernel v8 seems to be the default one with 4.19.75 also on PI3B+ .. is it true? I had to force, in config.txt, the kernelv...

For what I see, many scripts in the linux-headers-4.19.75-v7l+ dir don’t work. I needed to make recompile all scripts .. they are probably 64bit version :o

Re: .Net Core Avalonia UI Frozen

I figure out the problem and now compile and run on Buster (I missed a using directive) (net core 3.0 rc1). This is a mess anyway becouse nightly build seems NOT to run on Stretch, and MessageBox class is not working anymore. So I will wait next release and check again. I need a runnable program for...

Re: .Net Core Avalonia UI Frozen

Pi4 renamed wwan0 interface..

I'm using QMI interface with a Quectel BG96 modem. This creates WWAN0 interface on the Pi. A couple a days ago, without any notice, on Pi4 (Raspbian Buster) my "wwan0" interface became "wwp1s0u1u4i4" ... ouch! This didn't happen on Pi3 (stretch). Can I reset to default name wwan0? How can be done? :?:

Re: Pi 3 b+ and waveshare HAT

Hi VanVince,
I think you need to move join PWR to P4 (BS0-H3). This will connect POWERKEY Pin to BCM pin 4 (pin 7 of the connector). Setting pin BCM 4 to 1 will start power to SIM7000. I don't remind if it needs a steady 1 or just a 100ms pulse to start modem.

I read somewhere, that microchip lan951x chip production has changed recently for some weakness in the industrial model due to temperature. I can’t remind where I got the news, but this was not related to Pi.

To me is not really clear what Farnell, in my country, sells as Computer Module Kit "RASPBERRY-PI RPI-COMPUTE3-KIT Raspberry Pi Compute Module 3 Development Kit" ... They show 2 CM3 boards included with 1 CMIO board, but I'm not sure you get 2 CM modules.
