NetBurner Community Forum

Good morning, we are developing on MOD5441x.

For production devices, we need to disable the download of application through Ethernet, to prevent any unwanted remote device flashing. We searched the forum, but we were not able to find the information we need. We have tried to use alternate boot monitor, but when giving the command WriteProtect, it answers "Unrecognized command". Is any other commands available? Moreover, does "Write Protect" mean flash write protect, or does it refer to any other memory device like sd card?

This is what we see in MTTTY alternate boot session:

Thank you.

The only way network downloads are enabled in an application is if you call EnableAutoupdate(). So just delete that function call.

Thank you very much.
