Part Number:LM3914
Hi,
My customer is using LM3914V ans has issue below.
Could you let me know causes and solutions, please?
The circuit is showed the attached file.
Issue 1 : LED1 always lights a little.
Issue 2 : There is the case of different sequence of lighting LED by resister setting.
For example, LED2 -> 1 -> 2 ->3....

Hello,
I want to program flash using usb_flash_programmer provided in c2000. I connect my microcontroller with PC via USB and on PC message coming " TMS320F28X7X USB BOOT LOADER" (please see the screen shot)
But when I run usb_flash_programmer utility and use the example "blinky_cpu01" and "F2837xD_usb_flash_kernels_cpu01" using command "usb_flash_programmer.exe F2837xD_usb_flash_kernels_cpu01.dat blinky_cpu01.dat" then I getting message .
"
Error enumerating device interface: 0x0103
This may mean that the device is not attached or the driver is not installed
Error: Couldn't open the USB device
PS C:\ti\c2000\C2000Ware_1_00_06_00\utilities\flash_programmers\usb_flash_programmer>
"
I think this error come because I am using example file for F2837xD and I am using TMS320F28377S. So please tell how to generate both files for TMS320F28377S.

Hi Linda,
Thanks for your feedback. Please refer the attached pdf file. I have made changes in schematic as suggested by you. Please validate the same.
Also, I want to control dimming using WiFi or BLE or any other external RF-SOC. For this, I need 3.3V or 5V power supply. Is the auxiliary power supply is available in this design? If yes, can you help me to find out the pin from which I can take the 3.3V or 5V power out? If no, can I use LM2596 as buck converter to get it from 40Vout pin or do you suggest any other chip?
Thanks.
Best regards,
Amit

Part Number:OPT3101EVM
Dear Technical Support Team,
I'd like to know general spec of OPT3101EVM.
①How is the FOV?
②How is the max / min distance?
OPT3101 datasheet shows up to 15m, however I think that distance and FOV depend on the lens mounted on EVM.
③How is the operation temperature of EVM?
→EVM has temp sensor and it calibrate itself.
However EVM user guide doesn't have the operation temperature.
Best Regards,
ttd

Part Number:TMDSEMUPROTRACE
Tool/software: Code Composer Studio
Hi
Recently my company purchase an XDS560v2 PRO TRACE Receiver & Debug Probe from Spectrum Digital.
I saw on TI.coom.It said that the Trace receiver can monitor the entire device by capturing system events such as the state of processing cores, internal buses and peripherals
I confuse that how to monitor peripherals of devices on CCS,like spi or EMIF ?
I try PRO TRACE on EVMK2H, software is CCS 7.3
Does anyone has document ,example ,or videio about how to trace peripherals?
Thanks and Regards

Part Number:AM5718
Tool/software: Linux
I have a AM5718 custom board. The board has QSPI boot options.
(0b000110 : First device SD / Second device QSPI_1)
we had it working in u-boot 2018 in linux SDK 05.00.00.15
SPI boot is not working properly . we are facing following errors
Below is a QSPI flash boot failure log.
U-Boot SPL 2018.01 (Dec 26 2018 - 15:52:46)

Invalid bus 0 (err=-19)
Failed to initialize SPI flash at 0:0 (error -19)
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###
But, After booting to the SD card, the spi flash will work normally when the sf probe is used.
Below is sf probe log after SD boot.

Part Number:TM4C1290NCPDT / TM4C123AE6PM
Hi,
DATA SHEET of TM4C123A/1290 said 2.5uF-4.0uF capacitor is required for LDO.
So my customer used 3.3uF, but capacitor makers are discontinue.
Can they work correctly on 4.7uF capacitor instead of 3.3uF?
The reason of this question is capacitor maker continues supplying 4.7uF capacitors and pin-to-pin compatible capacitors.
Also, Capacitor has the frequency-characterization. Does TM4C require 2.5uF-4.0uF capacitors on DC component only? How frequency range is required on 2.5uF-4.0uF capacitors?
My customer is urgently re-making the board. Please advise me.
Thanks and best regards,
M.HATTORI.
Hi Team,

Part Number:TMS320F28379D
Tool/software: TI C/C++ Compiler
Hi,
I was wondering how this problem is solved? Because I'm in exactly the same situation here. Also if I zip the project and send it to my colleague, he is able to open and debug the project, algorithm works fine but when it comes to running the motor, DC bus current increases dramatically (which is never happened in my case). All compiler settings (include options, linker option etc.) are exactly the same in these two projects.
My compiler version is 15.12.7. And I'm running the code from ram.
I would be glad if can suggest anything.
Thank you,
Eray

Customer is looking for a single chip to support 2.1 sound audio amp. please find enclosure for the conditions and topology.
Part Number:LAUNCHXL2-RM57L
Tool/software: Code Composer Studio
I want to get started with this Board.
I wrote very simple program.
int main(void)
{
const int a=5,b=10;
int c;
c = a + b;
return c;
}
I am using GNU compiler. Default linker options are there.
For Debug Connection i am using XDS110 USB now I am trying to debug and setting breakpoint on main. Its not able to do so.
ERASE and FLASHING is Done but debugging is not allowed.
One Warning is coming: "Memory Map Setup for Flash @ Address 0x0 due to System Reset"
Please let me know if anyone has the same problem
Part Number:TAS2557
I use the EVM board to debug.
I connect the EVM , and open the Audio processing page of PPC3 tool, It will auto download some cfg,
then I try to adjust the gain, it can work normally.
Then I download the " combined_configuration_0_ROMMode1_48KHz.cfg " to put the TAS2557 into ROM Mode 1,
and use the IIC cmds generated before to adjust the gain, but it does not work, the audio gain has no change.
The IIC cmds generated in the Audio processing page of PPC3 tools seems have no effect to adjust the aduio gain in ROM Mode 1.
Why?
But I have find that I can directly wirte to the SPK_GAIN_EDGE reg to adjust the output audio Gain.
And also how can I adjust the EQ?

Part Number:AWR1642BOOST
Tool/software: Code Composer Studio
I had read the PDF file of "AWR1xxx Data Path" , and traced the Demo Code of MMWave SDK 2.0.
Then, I know how to transmit the ADC Data to CBUFF by EDMA, and the EDMA was set by using the CBUFF_createSession function.
Now, I want to transmit the detMatrix of L3 memory to CBUFF , but i can't find the source address in the EDMA setting of LVDS.
I would like to know if I could change the source address in the EDMA setting of LVDS to the address of detMatrix.
Thank you.

Part Number:TPS65987D
Hello
1.can we set TPS65987D's I2C channel in Master mode so that it can control BQ25713 and read the status of BQ25713 through I2C??
2.we have 2 PCS TPS65987D and 1 PCS BQ25713 in the system, we want to set TPS6587D communicate with BQ25713 through I2C channel.
The question is: Both 2 PCS TPS65987D are set in I2C Master mode, and BQ25713 is set in I2C slave mode, and this I2C channel has 2 Maser and 1 Slave, can they work normally？
Thanks
Part Number:WL1837MODCOM8I
Dear Team
One of my customer has below question:
In WL1837 board, there are LC matching circuits on the board SMD antennas. But for the optional micro-coax connectors (which were disabled by default; but we enabled them by turning two jumper resistors) there are no LC matching circuit. They are directly connected to the module; as can be seen in the attached picture. Is the LC circuit only needed for on board SMD antennas? Should we also put LC circuit to microcoax connectors? (In our system we are using microcoax connectors to carry the signal to an external antenna.)
Could you please help?
Best regards
