RTOS/AM5728: Lockup issue(-1323, Pipeline stalled) for customer EtherCAT Master board..

Part Number:AM5728

Tool/software:TI-RTOS

Hi all,

I am following up the customer lock up issue on the AM5728 MPU0 for their EtherCAT master board.

At that time, I tried to attach the MPU0 core but I can't attach the JTAG after lockup happened.
But at that time, JTAG message shows -1323 which noted pipeline stalled.

It is similar issue with the below e2e post.
https://e2e.ti.com/support/arm/sitara_arm/f/791/t/637787?tisearch=e2e-sitesearch&keymatch=pipeline%20stall

Customer and I are investigating the root cause, and checking the address right after -1323 @ 0x_xxxx_xxxx.
I think the address specified in the JTAG error log and its nearby address could be a key points.
The address is not fixed but it shows some functions so far.

At first, the address pointed terminal message function, so we removed UART terminal messages and its function.
And then it pointed cache_invalidate() function which is related OCMC shared memory. (actually they do process many data from PCIe and MPU0).
Sometimes, the address points at the customer's 3rd party's library, the address point out to the jump command.

One of question is, 
What does pipeline stall means, why this pipeline stall issue happened and when?

Could you please help me with your opinion?

Best Regards,
Ernest Cho.

Hi,

Our customer has a question bout below description on datasheet.

What's different for the initiate charge cycle and the during charger cycle?

Why the threshold is same VT1 and VT5?

Can you give some comments about it?

I'm a writer for AllAboutCircuits.com.  I've created a project around the CC2640 -- Everything works as intended, but I'd like to have a TI application engineer from that division have a look at the article prior to publication to ensure I'm not explaining something incorrectly, or done something unforgivable on the PCB.

Thanks,

Tool/software: TI C/C++ Compiler

Hello

I am a beginer in zigbee network.

I want use uart in generic_app in z-stack 3.0. I config uart in function zclGenericApp_Init :

halUARTCfg_t uartConfig;
uartConfig.configured = TRUE; 
uartConfig.baudRate = HAL_UART_BR_115200;
uartConfig.flowControl = TRUE;
uartConfig.flowControlThreshold = 48;
uartConfig.rx.maxBufSize = 128; 
uartConfig.tx.maxBufSize = 128; 
uartConfig.idleTimeout = 6; 
uartConfig.intEnable = TRUE;
uartConfig.callBackFunc = NULL;
HalUARTOpen (HAL_UART_PORT_0, &uartConfig)

after I put


uint8* mes= " UART0 Message ";

if ( keys & HAL_KEY_SW_1 )
{

HalUARTWrite (HAL_UART_PORT_0,mes,sizeof(mes));
}

in 

zclGenericApp_HandleKeys function.

in IAR preprocessor , i define 

HAL_UART=TRUE
ISR_KEYINTERRUPT
HAL_UART_DMA=1

But when i press key 1, no message trans over uart port.

Can you tell me where is problem ?

Thanks

TDA2EG: 2D Surround View Calibration Issue

Part Number:TDA2EG

Hi

     I am studying how to calibrate the 2D Surround View.

    According to the "VisionSDK_UserGuide_2D_SurroundView_Demo.pdf":

    1 first, i should use the fisheye distortion center tool to get the center position of 4 input frame;

    2 then, i should use the calibration tool to get the initial perspective matrices;

    3 But, how about GAlignLUT table? Except for contact FAE, is there any other ways that i can update the GAlignLUT table by myself?

    By the way, could you explain more about the information of GAlignLUT table?

    for example, distortion centers describe the 4 input frame's distortion centers from vertical to horizontal one by one; and  initial perspective matrices describe 4 camera's matrix (3*3) one by one.

    So what the physical description of  GAlignLUT table' information? It is a real huge array...

Thanks

Hi,

    I just recently downloaded SDK v1.50 and I would like to know what is the difference from SDK v1.40. Here are some questions below.

  1. SDK v1.50 Off-Chip OAD App only download time is very fast at 20 seconds, However using SDK v1.40 Off-Chip OAD App only takes 3 minutes to finish. What are the improvements at SDK v1.50 Off-Chip OAD example program that able to achieve fast OAD download time of 20 seconds?
  2. Why is that the SDK v1.50 does not have BLE 5 Stack included?
  3. What bug fixes have been done at SDK v1.50?

MSP430FR6047: Problems with EVM430-FR6047 test results

Part Number:MSP430FR6047

hi,

I use the EVM430-FR6047 2.0 to test the flowmeters DN50 and DN32. The test results of the DN50 flowmeter are basically the same as those described in the white paper,Zero flow drift measurement data is good. However, with the DN32 flowmeter, the test results are very unstable.The following is the DN32 flowmeter configuration and sampling results.

DN32 is In-line and reflective transducer placement and DN50 is In-line and diagonal transistor placement.Does this mean this measurement method is not suitable for in-line and reflective transducer placement?

CCS/ADS1247: Burn-out Detect Current Source

Part Number:ADS1247

Tool/software: Code Composer Studio

Hello,

I am using ADS1247 and basically I want to detect when the sensor is disconnected. I looked at datasheet in the page 34, section 9.3.9 describes what I want. Hence I used the Burn-out Detect Current Source Register in MUX0 and set it to 0x41. I am using AIN0 as positive input and AIN1 as negative input. If sensor is not connected, I am supposed to get full scale reading, i.e, 7f ff ff. But I am not observing that. I am getting 0x5528A6. Here, the lower 2 bytes are varying and the 1st bytes which is '55' is remaining constant. I tried with 2uA and even 10ua but results are same.

I am sending values in this way-

0x40 - to select WREG

0x03- to write to 4 registers

0x41- MUX0- 0.5uA, AIN0, AIN1

0x00- default

0x00- Internal clock and normal operation

0x15- gain is 2, output rate is 160sps

To verify whether I am writing properly, I even read back the registers and it was correct.

What am I doing wrong ? Can anyone guide me?

Regards,

Adhitya

CCS/TMS320F28035: How to set or change values of variables in watch window under debug mode

Part Number:TMS320F28035

Tool/software: Code Composer Studio

Hello,

I am doing emulation on a ILPFC c2000 development board where the controller is F28035. My CCS is version 7. The user manual of the development board gives instructions for incremental builds of the control loops and I have trouble following one of the instructions. For open loop emulation, the instructions suggests to add a variable 'DutyA' in watch window and change the value of it to change the duty ratio. I was able to add it in expression tab and see its value but not able to add it in 'variable' tab. The variable tab is empty and there is not an option 'add variable' when right click in the tab. I also noticed I can click the value of 'DutyA' in expression view and input a new value but it will not stay and will go back to the initial value after hitting enter key. It makes sense that expression tab is only to watch values during debug and is not for setting variable values but why making it possible to click and change in the value column in the first place. Bottom line is I want to update the duty ratio value on the fly in debug mode as opposed to having to change value in the code and recompile. The user manual makes it sound like a simple task to add and change 'DutyA' value but does not elaborate how to do it. Any help or suggestions will be greatly appreciated.

TMS320DM8168: Execution of Video Processing Algorithms on DSP

Part Number:TMS320DM8168

Hi all,

I have developed One application using Qt 4.8.5 and OpenCV for video capturing, Processing (Automatic Video Tracking) and Display. Video Capturing and Display is done through V4L2 libs which is quite fast, No delay is observed.

processing is done using OpenCV libs which takes lot of time on ARM processor (more than 100 ms per frame).

I want to run the Video Tracking Algorithms which is developed using V4L2 and OpenCV libs on ARM processor using DSP core also.

The Video Capturing and Display can use ARM core and the Video Tracking Algorithms can run in DSP.

I have no idea how to configure the ARM and DSP for this, what are the tools to be used, what will be the framework of my application etc..

Any suggestion on the above subject would be highly appreciable.

Thank You.

Dear TI experts,

   Would like to ask if CC3200 supports APSD? APSD somehow is the advance option in WMM scheme.

   And i have read another previous post (link as shown below) in forum states that CC3200 is WMM-certified. 

Reference post link: "e2e.ti.com/.../384380

   The reason i am asking is because we are trying to optimize our product using CC3200 with new routers with these options available.

   Thank you very much for your kind attention.

Yours faithfully,
