Hi,
I correctly configure my LPC55S06 to use secure boot and Debug Authentication.
I have an issue I can't go to ISP mode from "nxpdebugmbox ispmode -m 0" command.
How can i do that?
Can i allow this command only for people with correct credential (as defined by AN13037)?
Thanks for helping me
Hello ,
Below is information from SE, you can refer to:
"
The root cause is the command should use "-n" parameter.
The tool always exits from debug mailbox after successful authentication when “--no-exit” parameter is not used. But when you need to execute “enter ISP” command, you should not exit the mailbox to remain in authenticated state.
nxpdebugmbox -p 1.0 auth -b 0 -c dck.dc -k dck.pem -n
Also, need "-n" for "Enter ISP Mode", this avoid the reset and keep the debug permission.
nxpdebugmbox -n -p 1.0 ispmode -m 1
