Hi there, I wanted to upgrade my multi-purpose RasPi 3B to a RasPi 4 due to RAM constraints. I use the Dragino PG1301 as a gateway and just followed the instructions ([https://www.dragino.com/downloads/downloads/LoRa\_Gateway/PG1301/PG1301\_UserManual\_v1.0.6.pdf](https://www.dragino.com/downloads/downloads/LoRa_Gateway/PG1301/PG1301_UserManual_v1.0.6.pdf)). When I check the status of the service, I get: Process: 1402 ExecStartPre=/usr/bin/reset\_lgw.sh start (code=exited, status=0/SUCCESS) Process: 1415 ExecStart=/usr/bin/lora\_pkt\_fwd (code=exited, status=203/EXEC) Process: 1416 ExecStopPost=/usr/bin/reset\_lgw.sh stop (code=exited, status=0/SUCCESS) When I check the logs using “sudo journalctl -u lorapktfwd -f”: **lorapktfwd.service: Failed to execute /usr/bin/lora\_pkt\_fwd: No such file or directory** But the file is there, so I tried to edit the permissions using “sudo chmod +x /usr/bin/lora\_pkt\_fwd”, which didn’t help either. Any ideas are appreciated 🙂 Thanks, Benjamin ---

Try running ‘file /usr/bin/lora\_pkt\_fwd’ and post the output… ---

Are you using the 32 bit version of the Raspberry OS on your system? ---

No, 64-bit… ---

Based on the direction you went to, I have installed a 32-bit Raspi OS on my machine, now it is working. But do you have suggestions what to do if I want to keep the 64-bit OS? ---

Two options: - compile the packet forwarder as 64 bit application - use the 32 bit binary with the required shared libraries it depends on (ldd should list them) ---

Got it running now on a 64-bit RaspiOS. Actually, I was already pretty close to the resolution as in the instructions, Dragino also shows how to compile the pkt-fwd. Unfortunately, the repo is not only anymore, so I didn’t go this route as this meant, I need to use some other forwarder. Now I did it using [fhessel/dragino\_pi\_gateway\_fwd](https://github.com/fhessel/dragino_pi_gateway_fwd). Compiling it on a 64-bit system will also produces the app in 64-bit. Thanks for pushing me into the right direction! ---
