Hi,
Just an FYI that when I upgraded, thread aware debugging no longer works due to this:
Received symbol: xDelayedTaskList1 (0x00000000)
ERROR: Mandatory symbol xDelayedTaskList1 not found.
Regards
Alex.

Thanks for taking the time to report this - really appreciate it. Which
debugger plug-in are you using?
This will be because the variable is now function scope, rather than
file scope, although the pointer to it is still file scope. That
particular change can be reverted - it was just neater and removed a
lint warning.

Hi Richard,
So its Segger’s JLink plugin e.g. /Applications/SEGGER/JLink/GDBServer/RTOSPlugin_FreeRTOS.dylib…
Its the latest version and both OSX and Windows behave the same.
Regards,
Alex.

There is also a problem with Segger Ozone and the FreeRTOS plugin.
I’m using Ozone 2.56u, STM32H7 Nucleo with reflashed STlink on-board adapter.
FreeRTOS 10.0.0:

FreeRTOS 10.1.0:

same result after moving xDelayedTaskList1 ,2 from function to file scope (but I don’t get an error message in Ozone either!)
There seem to be a lot of internal changes between 10.0.0 and 10.1.0… likely Segger will have to update their plugins.

Can you please try moving the two lines:
PRIVILEGED_DATA static List_t xDelayedTaskList1;
PRIVILEGED_DATA static List_t xDelayedTaskList2;
out of prvInitialiseTaskLists() to instead be function scope as they
were in the previous version and let me know if that fixes the problem.
Thanks.

It works, if the same order of Lists as in 10.0.0 is restored, i.e.:
/* Lists for ready and blocked tasks. --------------------*/
PRIVILEGED_DATA static List_t pxReadyTasksLists[ configMAX_PRIORITIES ];
PRIVILEGED_DATA static List_t xDelayedTaskList1;
PRIVILEGED_DATA static List_t xDelayedTaskList2;
PRIVILEGED_DATA static List_t * volatile pxDelayedTaskList;
PRIVILEGED_DATA static List_t * volatile pxOverflowDelayedTaskList;
PRIVILEGED_DATA static List_t xPendingReadyList;
If I move the definition of xDelayedTaskList1/2 somewhere else, Ozone doesn’t find it. It seems to take the position of pxReadyTasksLists and assumes the other lists in fixed order.

The problem seems to be much larger.
To my knowledge and understanding it is not about the order of these variables. I have ported a few applications to 10.1.0. I can confirm that the Segger debug awareness is not working any more with Eclipse (gdb based debugging). I guess it is because of changes in the task descriptor from 10.0.1 to 10.1.0.
It affects as well the NXP FreeRTOS plugins (https://mcuoneclipse.com/2016/07/06/freertos-kernel-awareness-for-eclipse-from-nxp/) which are not not able to display the tasks any more. I’ll keep digging into the reasons what is causing this.

Hi Erich - appreciate your help - need to fix asap.

Good info - thanks.

FYI - the IAR task aware plug in works fine with V10.1.0. The StateViewer tasks window works fine also, but the queue window needed the struct QueueDef_t type renaming back to its original struct QueueDefinition name to work. This was a very minor edit. Will look at the Eclipse StateViewer plug-in next.

This also fixes the problem for me (vanilla openocd-0.10.0). Openocd is the backend that most of the eclipse/gdb based stuff is using…
rtel wrote on Monday, August 27, 2018:
Try the code in the head revision of SVN now - it works with the Eclipse and IAR StateViewer plug-ins. I’ve not tried the Segger one yet. Please let me know your findings.
rtel wrote on Tuesday, August 28, 2018:
The head revision in SVN is now working with the Segger plug-in again. Please verify.
@Erich - can you please check the head revision is working for you too.
Once I hear back I can provide a patch release so the plug-ins are all functioning again.

Please try V10.1.1 - just released.
thomask wrote on Saturday, September 08, 2018:
Ok, Segger Ozone seems to work again!
But Segger SystemView 2.52b timeline now shows tasks in arbitrary order, instead of sorted by priority 
Unfortunately, I don’t have time to investigate further at the moment.
