Hello, I am flashing core-image-minimum Yocto image to Hummingboard AIOT. I am following “Flashing QSPI flash” under “Manual Firmware reflashing” section in [https://solidrun.atlassian.net/wiki/spaces/developer/pages/722042882/HummingBoard+Hailo+15+SOM+Quick+Start+Guide](https://solidrun.atlassian.net/wiki/spaces/developer/pages/722042882/HummingBoard+Hailo+15+SOM+Quick+Start+Guide) . But I am getting the following error.

UART recovery firmware version which is now loaded: 1.4  
Error: [Errno 13] could not open port /dev/ttyUSB0: [Errno 13] Permission denied: ‘/dev/ttyUSB0’

Can anybody help with that. I have set the DIP swith in QSPI mode(000001)

the error you are getting is a permissions error for the USB device. You can run the command with sudo to elevate the permissions, or add your user account to the group that is given access to serial devices, usually dialup or something similar.

Thanks for your reply. The issue was from my side. Once I had stopped all networks in pc, I could successfully flash it.
