AM3359: NIMU_ICSS issue

MarioP12

Part Number: AM3359

Hello,

because of an unknown issue with the "NIMU_BasicExample" (see ) I tried the same code (Source and Header Files) with the "NIMU_ICSS_BasicExample".

Here the situation is a bit different. Interestingly , the mentioned exception doesn't appear when I call connect().
But, now I get (6) as return value which says this is Error ENXIO. Referring to the Guide it says that I have to declare a special SocketOption, but I use StreamSocket Communication where this option should not be necessary. This is the result, when I create the respective task with a priority of "5".
Another very interesting thing is, that when I create the task with priority "4", then I don't get this return value. Additionally, I can't see any console information (system_printf is not activ?!).
However, the communication works with priority "4" and for me it would be interesting why?!

If I call the "TcpEchoServer" I get again this strange exception (as in the above mentioned post), when I come to the accept() in line 105.
This is also a bit confusing for me.

I will add the current source and main file for investigation.

Mario,

>>Here the situation is a bit different
Did you change the CPSW/ICSS jumper setting on AM335x ICE v2?
processors.wiki.ti.com/.../AM335x_SYSBIOS_Industrial_SDK_Getting_Started_Guide
... CPSW can be selected by connecting a jumper pin between pins 1 & 2. ICSS can be selected by connecting jumper pin between pins 2 & 3.

Regards,
Garrett

Hello Garrett,
Of course I changed the jumpers.
Otherwise it would not work in task priority "4" as I mentioned above.
The problem must be different.

Mario,

NIMU_ICSS_BasicExample_icev2MA335x CCS project includes netHoooks.c that creates dtask_tcp_echo daemon, have you tried to enable it in .cfg file instead of using files from industrial SDK 1.0?

Global.networkOpenHook = '&netOpenHook';
Global.networkCloseHook = '&netCloseHook';

Regards,
Garrett

Hello Garrett,

Unfortunately, enabling the "OpenHook" and "CloseHook" in the config-File doesn't solve the problem with the task priority >4.
Is there an additional modification necessary?

I am not sure if there are any files connected from the industrial SDK, because there is no link, no include and no library used within my project.

Hopefully you have further ideas regarding my problem :-(

0 Garrett Ding over 9 years ago in reply to MarioP12

TI__Mastermind 43296 points

Mario,

The ndkThreadPri is set to 5, see "Properties' of NDK core stack when openning nimu_icss_arm_wSocLib.cfg with XGCONF. This may explain why your task priority need to be lower than 5.

So you have removed industrial SDK dependence? how does your project build log look like?

Regards,Garrett

0 MarioP12 over 9 years ago in reply to Garrett Ding

Hello Garret,
if you mean the "Network Scheduler Task Priority" then I have to say, that I increased it to "High Priority".

As you can see on the attached screenshot, the NDK Stack Thread runs in priority 8.

Nevertheless, it is not possible to connect to a socket() with task priority 5.

Yes ... Every dependence should be removed. See the project build log:
1731.buildlog.txt

Any new ideas regarding my issue with higher task priorities?

0 Garrett Ding over 9 years ago in reply to MarioP12

TI__Mastermind 43296 points

Mario,

The Priority level for normal priority NDK tasks is set to 5, which results in the daemon function priority to be 5. You may try to increase this and see if it changes the behavior with your higher priority tasks.

Regards, Garrett

Hello Garrett,

thank you for your response. I have tried your suggestion and I think this works.
I have know configured the following situation:

Setting the Task-Prio to 5 now enables the System_printf() to the Console.
But, I can not understand the reason for 100% and I would like to do so ..

Maybe you could explain me in some short sentences the reason for this behavior ... This would also be interesting for the future
