Re: Why are Raspberry Pi still using Java 8 when Java 11 is available?

It's probably not going to be updated anymore and Buster will only have OpenJDK. Unless there's some reason to ship newer versions of Oracle Java 8 & 9? An update to 1.8.0_202 would be good as there a quite a few people running UniFi controller of a pi that are having issues https://community.ubnt....

Re: (New) Official nightly full and cutdown/headless images

Are the official jessie images and these nightly builds still build using the same process and is that still using spinlde as found here https://github.com/RPi-Distro/spindle ? We at WirelessThings would like to offer customised version of the official jessie images using a tweaked version of the im...

Re: Serial ports -- using both

You need to make sure you have a device connected to the serial port before opening it with something like minicom

Re: Serial ports -- using both

Thank you dpslwk for your detailed instructions. You are right, of course. I missed the overlay part. Now it is working great here as well. And thank you all who contributed to providing the UART1 support in the stock RPi kernel. Ondrej With the overlay you do not need to do any pin changes in the ...

Re: Serial ports -- using both

If your setting pins with wiring pi make sure you use the -g switch so the pin numbers are the actually BCM pin numbering scheme If your using the linux 8250 driver you need to add something to the BCM's kernel init file to enable the AUX peripheral For me that looked something like this arch/arm/ma...

Re: i2c0 dual camera and HAT eeproms

edit: read the OP HATs are not probed on compute modules. Thats disappointing, I'm working on the design for the OpenPi and had included a ID EEPROM thinking that we could push DT overlays for our CM board, then a user could just load a stock raspbian OS images onto a CM, boot it and have it automa...

Re: Serial ports -- using both

Just an quick update I actually got this working. Big issues seemed to be getting the pins configured to ALT5 Using dt-blob.dtb does not seem to be having any effect, not sure why yet and using $ gpio from wiringPi to set pin 14&15 I had my numbering out by one so doing the following currently works...

Re: Serial ports -- using both

I've been trying to get this running on a compute module but with little success. I can get the module built and loaded see the new /dev/ttyS0 but every time I try to open the port with minicom or screen e Pi just freezes. Has any one else got this working and what steps did you follow? Here are are...

Re: EVE Alpha: In search of passionate linux / RasPi users /

Hi We have a mix of interface's to go with the mix of radios, but yes most are on the SPI bus. The Xbee socket is on the UART The EnOcean is on a UART to I2C bridge, we had intended to use SPI but found out the EnOcean's SPI is master only. On the SPI we have the following SRF 868Mhz RMF12B Z-Wave S...

Re: Slice of pi - GPIO breakout board

The Slice of pi is 52.5mm x 36.5mm and so should stay just with in the size of the R-Pi.

Looks like my R-Pi is not going to be here for another 4 weeks so can't check for myself till then
