On a brand new MOD54415-200IR module, when I power it up the serial port spits out:

App Header Failed
No Valid app

App Header Failed

NetBurner MCF5441x SPI Boot Monitor V1.06 Feb 28 2020 18:20:21
HELP for help

Using the serial terminal MTTTY, I uploaded MOD5441x-FactoryApp_APP.s19 (from v2.9.5) and when it finished, the terminal output was:

Code: Select all

Starting address = 40000490
S Record End detected

And then nothing. A reboot does the same thing.

Is there any way to recover this module?

Yes, have you tried the shorting jumper recovery procedure? https://www.netburner.com/NBDocs/Develo ... overy.html

Yes, I tried the shorting jumper. It didn't help. I have two modules in this state. Both are new. The serial output of the first one is what I put in my first post. Shorting jumper TP1 during bootup produces the same messages as above. It doesn't appear that the Alternate Boot Monitor is started.
The second module has a higher rev monitor so its output is a little different. On bootup with TP1 shorted the output is:

Code: Select all

Configured Mask= 255.255.255.0
