RAK5146 Gateway Concentrator Module for LoRaWAN - Cross compilation in arm64

Hello,

I need help with the RAK5146 Gateway Concentrator Module (mPCIe to USB board). We are integrating this module with an i.MX8MP for AWS data transfer using the Basic Station code from this guide.

We first compiled the code on an x86 system so we can do this all steps to transfer data by proven guide first as a test and then will do same with the ARM64(aarch64). However, when running it with generated the station binary and our AWS credentials (tc.key, tc.uri, tc.crt, tc.trust) and station.conf, we received the following error:

2025-03-06 12:45:38.857 [HAL:ERRO] [lgw_start:742] FAIL TO CONNECT BOARD
2025-03-06 12:45:38.857 [RAL:ERRO] Concentrator start failed: lgw_start
2025-03-06 12:45:38.857 [RAL:ERRO] ral_config failed with status 0x08

Could you please advise on how to properly set up the concentrator on x86 before moving to aarch64 integration? I’m happy to provide more details if needed.
