No channel 4 stepgen direction on Mesa 7i92T

I new I would mess things up. Now when I enter
mesaflash --device ethernet --addr 10.10.10.10 --readhmid I get
lbp16_access.send_packet: Operation not permitted
Aborted

HELP please

That usually means either LInuxCNC is running or LinuxCNC was not shut down properly

(LinuxCNC blocks access to its Ethernet interface when running and this block remains
if LinuxCNC exits ungracefully)

You might tray again after entering:

halrun -U

Thankyou. halrun -U solved the problem.
