Hello, I have recently got some used Cisco Meraki MR18's and tried to use JTAG to flash OpenWRT onto them. However, I have got issues as OpenOCD will not recognize the Meraki MR18 and I have read the documentation and I can confirm that the AP is wired correctly.
Here I include some screenshot's and pictures of the wiring diagram and OpenOCD error:
ohh, that's why it probably doesn't work as I only have the one ground connection.
Additionally what JTAG pin header is responsible for ground on the MR18?
I now have these messages
Error: isa info not available, failed to read cp0 config register: 0
