Hi Jason,
The problem we have isn’t specifically with ARM, but with the FTDI USB libraries on *nix systems. The restrictions exist even with x86 Linux systems. The FTDI libraries for our chip (both the ones provided by FTDI and the open source version) are unable to meet the throughput required for our device to operate optimally (for reasons unknown).
Additionally we know that using a Linux low-latency kernel on x64 will not have any restrictions. The same cannot be said for ARM.
So, the options as we have seen,
Windows: x86/x64 – full capability.
*nix: Standard kernel – x64 – limited functionality.
*nix: low-latency/real-time kernel – x64 – full capability.
*nix: ARM – (all systems we have tested) – limited functionality.
Let me know if you have additional questions.
Regards,
Andrew
