CCS/BOOSTXL-AOA: Queries in function: RTLSCtrl_estimateAngle

Part Number: BOOSTXL-AOA

Tool/software: Code Composer Studio

Hi,

If i am using only one array in BOOSTXL-AOA then which pair angle are getting averaged in this code snippet:

// Calculate AoA for each antenna array

const int16_t AoA_A1 = ((antA1Result->pairAngle[0] + antA1Result->pairAngle[1]) / 2) + antA1Result->channelOffset[antA1Result->ch];

As i will be having three antenna pairs in one array then why not averaging third one?

If i want to use only one pair then do i need to take only one pair angle with channel offset to compute AOA?

Please clear above mentioned doubts.

Thanks

Hello,

I am trying to find a way to extract "td" from CCSv9. I want to use it as standalone tool in CI for processing data dumped from TCI6638K2K

Could you tell me what is minimal set of files which are needed by "td"? I do not want to install CCSv9 to use single tool

So far, I am using "strace" linux tool to check what "td" is doing on different machines.

I observed the following libraries / files are required:

  • in /etc/ folder:
    • ld.so.cache
    • localtime
  • in /lib64/ , /lib/x86_64-linux-gnu/ or  /usr/lib/x86_64-linux-gnu/ folder:
    • libstdc++.so.6
    • libc.so.6
    • libgcc_s.so.1
    • libm.so.6
    • libpthread.so.0
    • librt.so.1
    • libpython2.7.so.1.0
    • libutil.so.1
    • libdl.so.2
  • relative paths:
    • emulation/analysis/xmldb/trace_config/devices/device_cc13x2_26x2.xml
    • emulation/analysis/xmldb/trace_config/devices/device_kepler.xml
    • emulation/analysis/xmldb/trace_config/devices/device_omap3430.xml

    • /home/<username>/.TI-trace/settings/CSSTM_0-STMCfg.txt.dcm
    • common/uscif/xdsalias.cfg
    Copying mentioned files helped on single machine but did not work on another. Could you help in finding dependencies?
    Please be aware that different commands may fail or work fine and td will not complain about anything. One must check if output file is corrupted or OK. The command I want to use is:

      "td -procid stm -devicekey 0x1B98102F -dcmfile 0x1431.dcm -bin 1431_crash_1431_60520000_8000_MEMDUMP.bin -rcvr ETB -app UlDspKeCpu1.out -timestamp abs -output trace_messages.csv"

Part Number: SN75LVPE802

Hi team,

My customer has the following problems, which are described in Chinese. I am not familiar with eye diagram test. I translate the questions from Chinese to English. If there are descriptions that confuse you, please point out.

1、U.2-1  without redriver : eye diagram test PCIE GEN3 RMS jitter fail,lan0-lan3 all fail,3.2~3.6ps, Shorter route, Intel spec less than 3ps

U.2-2  with redriver : eye diagram test PCIE GEN3 RMS jitter fail,lan0-lan3 all fail,3.7~4.2ps, Longer route

2、PCIE  GEN3 clock test：About jitter part test pass

3、Use the PCIe X4 and U.2 that passed the test to cross verify the clock and date eye diagram test:

U.2 clock + PCIE X4 date： RMS jitter pass.2 date  + PCIE X4 clock： RMS jitter  fail

4、Adjust DEW,DE,EQ, eye diagram changes, RMS jitter still fail

Help to see the relationship between RMS jitter fail and date, thank you!

I imported the "NIMU_BasicExample_evmK2G_armExampleproject" from the example projects and compiled successfully. then I tried to create a new project to implement the functionality of NIMU I am getting asm undeclared error.

I made all the necessary changes and configurations in the new project with the help of "NIMU_BasicExample_evmK2G_armExampleproject" this project still I am getting error.

I also changed the compiler options c99, when I change it I am getting different errrors.

could anyone please help me to resolve this issue.

When reading or programming request is run through the TI nowFlashWin.exe, the nowFlash.exe is executed and following log appears:
"nowFlash version 3.42 Build <official>

Check that the INSTALL_PATH and DRIVERS paths in the nowFlash.ini file represent valid paths, and that the specified driver exists in these paths.
***************************************************

The driver for Spectrum Digital xds510 is installed appropriately and the TI nowFlash application is configured. The SDXDS510USB device is connected. The driver can be found in the device manager version 6.0.999.2 2.40.0.1315.
Other devices (like xds200) and Uniflash work appropriately. The tested nowFlash config works appropriately on other PCs.

What is meaning of forcing the driver path using the "'-dll <driver>' option"?
What other system/Windows configuration may be checked?

TMS320F280049: ePWM: GLDPRD and SOCAPRD synchronization

Part Number: TMS320F280049

Hello everyone,

I'm using the TMS320F280049 for a power converter where the PWM frequency is a multiple of the control loop frequency. I'm using the SOCAPRD register to rescale the control ISR frequency.

I would like to transfer the PWM shadow register to active registers at the same frequency of the control loop, and I see that GLDPRD can help me but I have the following doubt:

Is there a way to ensure that SOCACNT and GLDCNT counts toghether, having always the same value or at least starting them at the same time? If I set the same value into SCAPRD and GLDPRD and their respective counters count together, the shadow to active transfer should happen at the same time the control ISR is called. Is there a way to ensure the synchronization between the two counters?

Thanks

Angelo

Hi,

I use TDA2EX_EVB connect to a camera.
The sensor output is Bayer RGGB 12 bit RAW data.
I am making a new chain
IssCapture -> (Bayer RGGB 12bit -> RGB888 or YUV420 )-> Display_video

I set :
pPrm->videoIfMode = SYSTEM_VIFM_SCH_CSI2;
pPrm->videoIfWidth = SYSTEM_VIFW_4LANES;
pPrm->bufCaptMode = SYSTEM_CAPT_BCM_LAST_FRM_REPEAT;

pPrm->outParams[0].dataFormat = SYSTEM_DF_BAYER_RGGB;
pPrm->outParams[0].inCsi2DataFormat = SYSTEM_CSI2_RAW12

than I get a error meaasge

The error message is from

because the dataFormate = 0x0056 is FVID2_DF_BAYER_RGGB

Is the setting correct?

Is TDA2EX supported this color convert?

IWR1642BOOST: COM port is lost during operation

Part Number: IWR1642BOOST

Hi team,

I have a trouble using IWR1642BOOST.

Use DEMOvisualizer in the cloud and start up normally.

Data has also been acquired.

However, over time, the connection is suddenly lost and the following error is displayed:

"No Texas Instrument USB ports detected. Please check your USB connections."

I checked the COM port in the device manager of the PC, but it is the same as before the error occurred and I can find the set port.

I think that virus security software may have affected, and installing and DEMOvisializer on a PC instead of the cloud does not change the results.

Does DEMOvisualizer installed on the PC also connect to the Internet?

I do not know what is happening.

Can you give me some advice?

Best regards,

Tomoaki Yoshida

LAUNCHXL-CC1310: Why do I see current peaks of magnitude 10mA after execution of chained RF Tx and Rx commands in 'rfEchoTx' example?

Part Number: LAUNCHXL-CC1310

Hi everyone,

I am working with rfEchoTx and rfEchoRx examples from simplelink sdk v3.20 using CCS v9.1 on LAUNCHXL-CC1310 boards. I have removed the while loop in rfEchoTx code so that the Tx and Rx chain od commands execute only once. However, on the DMM, I see current peaks of magnitude 10mA after the RF command chain is done executing i.e, after receiving acknowledge from receiver. 

Why do I see these periodic current peaks? Is there something else happening once the rfEchoTx node completes it's function?


Can someone suggest what can be done?

Thanks in advance,

Hi team, 

When running CCS, there is an error for c2000 compiler. Could you please tell me how to solve this? The notice is shown below.

This project was created using a version of compiler that is not currently installed - 6.4.2 [C2000]. See 'Help > Install New Software' and select 'Code Generation Tools Updates' to check if this compiler is available through a CCS update.

After following the hint of the system to install new software, the project still can’t be compiled. I think the 6.4.2 is installed but it can't be used.

 

Thanks.
