Part Number:TPS61046

Hello,

My customer has a question about Feedback voltage min, max data over the temperature from Tj=-40C to 125C. Could you kindly help our customer to show the Feedback voltage temperature data (-40C < Tj <125C) for both PWM and PFM case.

If you have any question, please let me know.

Best regards,

TDA2EVM5777: TDA2EVM5777: Connecting AWR1642BOOST to TDA2XX over DCAN1 and SocketCAN

Part Number:TDA2EVM5777

Hi,

We have Following environment :

  • TDA2xx – REV H board
  • VisionApplication board
  • AWR1642BOOST– Rev B board.
  • Omnivision Cameras
  • VisionSDK 3.3

[ More details are at :1230:0]

Assuming the AWR1642BOOST REV B  board is connected TDA2xx over DCAN1 interface (node 1 to node 2, no other nodes),

we have following question  from software side.

Q1.  It seems default CAN interface in AWR1642BOOST is MCAN (CANFD) while on TDA2xx - DCAN1 is CAN.

     So we need to configure the driver / application running on AWR1642BOOST to ensure the Classic CAN data is sent to TDA2xx

     This can be done by configuring frametype to  "CANFD_MCANFrameType_CLASSIC"  on AWR1642BOOST side software.

Can you please confirm ?

Q2. On TDA2xx - with VisionSDK 3.3 - Linux already provides and CAN driver and already integrated and tested with Socket CAN ?

Is that correct understanding ?

Q3. For further integration with VisionSDK F/W, one need to write a Link to read the data using Socket CAN and share with other links in chain as per the usecase ?

We would like to confirm if DCAN1 is controlled from A15 and not from IPU / M4. Please confirm.

Q4.  We could see the ISS capture but it seems to be using the VIP/ CSI interface ( via some CAN to CSI - FPGA), it will not be useful for above use cases.

Is there any already available link in RadarSDK / VisionSDK for reading data from CAN  ?

Thanks,

Uday.

Part Number:TMS320F28069M

Tool/software: Code Composer Studio

Respected sir,

I am working on TMS320F28069M launchpad. I am trying to run the LED blinking code for this device.

But while setting the target target configuration file I found that TMS320F28069M controller is not present in the list so I have selected TMS320F28069.

While debugging I am facing the problem as below

(Error -1135 @ 0x0)
The debug probe reported an error. Confirm debug probe configuration and connections, reset the debug probe, and retry the operation.
(Emulation package 8.0.27.9) "

The development is in the CCS v8 and the debug probe is XDS100v2.

I tried to run the code by taking another probe for debugging but facing the same problem.

I have also tried the LED blinking for this launchpad using Energia software. While selecting the target board I get to know that

TMS320F28069M launchpad is not present in Energia also so I have selected TMS320F28069 launchpad and faced the same problem

" error: C28xx: Error connecting to the target: (Error -1135 @ 0x0) The debug probe reported an error. Confirm debug probe configuration and connections, reset the debug probe, and retry the operation. (Emulation package 6.0.14.5) "


kindly request you to help me out.

RTOS/CC2650: Can TIMAC implent I2C communication to interact with another Sensor on the Sensor Tag?

Part Number:CC2650

Tool/software: TI-RTOS

Hi all ! 

I wonder if its possible that TIMAC Can use I2C protocol to comunicate with another sensor on the Sensortag cc2650, I have read the documentation file MAC Cop Interface Guideline and says that CC26xx MAC Coprocessor currently supports UART only. So I want to corroborate that ! 

If that's not true, I would ask you for help to guide me how implement it on the sample project on IAR please. 

I noticed too that TIRTOS can be an option to get the drivers to implement I2c communication, but when I tried to add the drivers to the workspace at compiling it launches an error. 

Hope everything its fine and wishing you an excellent day !

Part Number:BQ24232H

Hi Team,

My customer considers to use bq24232H for 4.35V(full charge) battery.
He is studying what is occured if 4.20V(full charge) battery is connected to bq24232H by mistake.

I heard the 4.20V(full charge) battery has OVP protection and switches off when battery voltage increases more than 4.28V.
Is there any concern?

Part Number:AM3352

Tool/software: Linux

I have custom board - based on AM3352 and I am using Linaro GCC 7.3-2018.05, ti-processor-sdk-linux-am335x-evm-04.03.00.05.

On my board I have wired Ethernet which is working, and I have one eMMC (NO SD-CARD).

I want to know how to transfer my uImage, rootfs  image to eMMC. 

I can transfer file from host to target via tftp in u-boot, but don't know how to format eMMC and write to it, how to package uImage, rootfs and any other files e.g. .dtb etc...

If someone can give me instruction that will be very helpful to speed-up my work, or any pointer will be also useful.

thx.

Hello

Thank you for your support.

My Customer is evaluating TPS92518 EVM, but did not have linear curve like as

TPS92518EVM users guide(Fig4).

I think this is not correct characteristics for TPS92518 EVM right?

 

Would you please advise what should be checked by themselves?

Customer’s condition:

Vin=48V,Vled=10V,

Peak threshold=244, Dimming 1KHz,

Off time=43 And Rshunt=0.307ohm

Using TPS92518EVM ( L, C, FET is not changed)

PWMx were from customer's MCU. 

Thank you for your support.

Team 

What is the condition of battery charging voltage regulation accuracy (-1% ~ 1%)

According to the Datasheet, Ta is 25 degree C for -0.5% ~ +0.5% but there is no condition for -1% ~  + 1%.
