Release 2.8.2 Errors

[SeeCwriter]

I installed v2.8.2 and rebuilt the system because I'm using SNMP, and it won't compile.

As installed, with IPV6 defined, these are the errors:

BEGIN:

This has been fixed. Contact support for the patch.

[SeeCwriter]

I contacted support and received some updated files. Now everything compiles without errors.

However, this release turned my application into a brick. Was there something that needed to be changed to be able to use this release?

My MOD5441X application runs fine compiled with 2.8.1. I see in the release notes a change was made to I2C. The last that happened I had all kinds of problems with the NANO until I changed I2C include files.

[dciliske]

uhh.... that's not good. Unfortunately, I have no idea what features you're using and/or what the component that might be failing to cause your application to "turn into a brick".

Function StartSnmpProcessor(SNMP_TASK_PRIO) never returns.

SNMP_TASK_PRIO = MAIN_PRIO-3.

[SeeCwriter]

This is a stab in the dark, but could the problem in StartSnmpProcessor() be related to OSTaskCreate(). Is the variable 'portnum' being passed correctly?

Code: Select all

   int portnum = SNMP_PORT;
   . . . 
   if ( OSTaskCreate( SnmpReaderMain,
                      ( void * ) portnum,
                      &SnmpStk[USER_TASK_STK_SIZE],
                      SnmpStk,
                      priority ) == OS_NO_ERR )

[SeeCwriter]

Had I bothered to check how 'portnum' was used in the created task I would have seen that there is no problem with the way it's passed. I was too busy getting my exercise.

[SeeCwriter]

So I followed the trail about as far as I can go. Ultimately, the problem is that function AddToIndex() in file Mibcls.cpp never returns.

Code: Select all

// Call tree...
StartSnmpProcessor(SNMP_TASK_PRIO);
   InitializeMibs();
      InitializeUDPSnmp();
         AddTableElementudpEntry( ( void * ) IANA_ECHO_PORT, IPADDR4::NullIP() , IANA_ECHO_PORT );
            AddToIndex( ASN_typeIpAddr, udpLocalAddress, len, IndexSuffix );  <-- never returns

void AddToIndex( int asn_type, snmp_typeCounter val, int &len, int *oidadd )
{
   oidadd[len++] = val;
}
