Hi @ShaneCCC,
On the Jetson Xavier NX, I haven’t known yet how to disable the firewall. I followed the relevant discussion to dump the address 0x15a00000 as below :
nvidia@ubuntu:~$ sudo devmem2 0x15a00000
[sudo] password for nvidia:
/dev/mem opened.
Memory mapped at address 0xffffbbd38000.
Value at address 0x15A00000 (0xffffbbd38000): 0x0
Could you help to instruct more about what register(s) you wanted to dump, please ?
