Hello!

I got a new starter kit and a NetDCUA5 board, which I connected to the starter kit. I powered the setup and, when I connect to the serial (using 115200 8N1, no flow control), both via PuTTy and via TeraTerm, it only displays what seems to be…

Anyone knows if this is this still an issue in kernel 5.15.148?

Thanks. It did not make any difference for me, but what actually worked was changing the chip select to use GPIO instead of native chip select line:

(Code, 7 lines)

Using GPIO instead of native chip select is also mentioned here:

but you are right, it should be active low by default.
For some reason, this device tree entry seemed…

I am currently using the heat sink that came with the evaluation package, which is a combination of the Heat Spreader PicoCore100 and Heat Sink PicoCore100.

Alright, thank you for the information!

After upgrading to Linux 5.15.148, the chip select on spidev on ecspi3 goes high when active instead of low. I've tested using unmodified device tree files on armStoneA9r2q. Running on kernel 5.4.70 works fine. ecspi2 spidev seems to work as expected.…

The temperatures look OK for me.
Other customers have reported similar temperatures.
Which heat sink are you using? Only the heat speader or an additional heat sink?

Running the board without the heat spreader is not recommended.
A peak load can lead…

Great news, F&S has created a library for easy integration of OSM into customers carrier board.
The library contains:

1. Schematic:

• library (fs_osm.olb) including:
  • general OSM symbol (V1.1, size S)
  • symbols of F&S OSM modules (module-specific

Hello again,

I am working with the PicoCoreMX8MM + FS-BaseBoard.
Currently I am taking a look at the temperature while running an UI-Application.

Setup:

• Qt-Application with simple animation (3 simultaneously moving arrows)
• Resolution: Full-HD

The crash happens with OpenJDK 11 - server.
The crash is systematic. I tested with different setups and different buildroot environments.

Meanwhile I could build successfully with OpenJDK 17 - server, and this version runs properly.
Note that I first…
