We are not using certificates. All we are doing is signing the firmware image using the private key created by OpenSSL.

The only reason this is coming up is because a customer is concerned that we used a version of OpenSSL that is out-of-date and no longer supported. At the time we started signing ...

For signing firmware images, we are using OpenSSL v1.1.1f, which I think was provided by Netburner. It's been about 4-years since we started signing images. In any case, is it possible to use the current version of OpenSSL, which I think is v3.5.0, to create the private/public key pair?

Am I ...

It turns out I was calling StartTcpUpdate at two different locations in my code. I'm running out of feet to shoot.

It turns out the return code for OSTaskCreatewName is defined in OSTaskCreate. And error code of 40 mean the task priority is already used.
These are my priorities:

#define USERMAIN_PRIO (55)
#define NTP_TASK_PRIO (54)
#define UDP_TASK_PRIO (53)
#define SNMP_PRIO (52)
#define FTP_TASK_PRIO (51 ...

StartTcpUpdate just calls OSTaskCreatewName, and returns the value returned by OSTaskCreatewName. But the uCosLibrary document doesn't define any return values.

Well, this is embarrassing. It is in my code. It's generated when function StartTcpUpdate returns a non-zero value, which in this case is 40.

At the completion of programming a Nano module using Autoupdate, v2.5, the following message is output on the serial port:

TcpUpdate Error: 40

The module is programmed correctly and runs as expected. I have detected nothing wrong. What does that message mean?

The applications are built with v2.9 ...

Any guidance on how we should proceed?

So there is nothing we can do to correct the problem. Yes, these are brand new modules. We bought these through a distributor, Mouser. Should we go through Mouser to return them, who is fighting us tooth and nail about returning these, or send them direct to Netburner?

Yes, we used the Alternate Boot Monitor to successfully download MOD5441x_FactoryApp_APP.s19 to both modules using the FLA command with MTTTY serial terminal. But the app never ran. The same error messages I put in my previous posts were issued.

Neither module was able to get an IP Address when ...
