switch to Operational Mode not working ?

[tinyaitmess]

After modifying the OD files of the demo folder with CANOpen Editor in order to automate PDO sending, the device is stuck in pre operational mode.
I ran the following and deleted persist files but it's still impossible to switch to operational mode and send PDOs :

cocomm "1 w 0x1011 1 vs load"
cocomm "4 w 0x1011 1 vs load"
cocomm "0 reset node"

[CANopenNode]

Check error register, emergency messages. If necessary, to switch to operational use:
cocomm "0 start"
