Platform Details:
Board: STM32MP257-dk and STM32MP257-ev1 series
OS: Linux (Debian-based, provided by STM)
Architecture: ARM64
.NET Version: .NET SDK 8.0.407 (linux-arm64)
SCADA System: Rapid SCADA (runs as a systemd service)
Description:
I'm trying to run a .NET 8-based SCADA application (ScadaAgentWkr.dll) on my STM32MP2 embedded Linux system. However, the application crashes when launched via systemd. Here’s what I’ve done and the issues I’m facing:
What I Tried:
Installed .NET SDK 8.0.407 for linux-arm64 from Microsoft.
Installed libicu packages:
Configured systemd service at /etc/systemd/system/scadaagent6.service.
Added environment variables to support ICU:
Environment=DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1 Environment=LD_LIBRARY_PATH=/usr/lib/aarch64-linux-gnu
Also tried using a wrapper script to export these before calling dotnet.
Error Logs:
From systemctl status scadaagent6.service:
Main PID: XXXX (code=dumped, signal=ABRT) Failed to start Rapid SCADA Agent.
Couldn't find a valid ICU package installed on the system. Please install libicu (or icu-libs) using your package manager and try again.
Goal:
I need to run the SCADA .NET app as a stable service on STM32MP2, with proper globalization support or fallback using DOTNET_SYSTEM_GLOBALIZATION_INVARIANT.
Request:
Can STM32MP2 Linux support full ICU with .NET 8?
Is there an official recommendation for using .NET services with systemd on STM32MP2?
Any known issues or limitations with libicu or environment variable propagation under systemd?
