Part Number: TMS320C6678

Hi,

   Using C6678 and last pdk version and TI edma example: configure EDMA3_DRV_SYNC_A mode, acnt=4, bcnt=ccnt=2 and use it with EDMA3_DRV_TRIG_MODE_MANUAL.

     I observed that the interrupt is triggered twice as it should be in this case: 8 times instead of 4 times (expected 4times = bcnt * ccnt).

    If you disable the transfer intermediate interrupt (comment this line: "paramSet.opt |= (1 << OPT_ITCINTEN_SHIFT)") I observed the interrupt is triggered only after the first transfer request, then the interrupt is no more triggered, even if it is not disabled.

    Is this happening on your side also?

    What exactly should influence the enable or disable of intermediate transfer complete for this scenario - how many interrupts should be received after every transfer request (4 in total for my scenario) in both cases: intermediate interrupts enable or disable?

Thanks

Hi,

I am trying to enable  interrupts for DSP core (for bare metal /non OS application). I'm already completed it in arm core using APIs( from the file named 'interrupt.c').Similarly how we enable interrupts in DSP core.??.i think it is not available in your sdk. Please share API documents regarding this.   

Part Number: TPS65235

Hi Experts,

Our customer is using our TPS65235 in their design, they found if they are not mounted D1 in below by mistake, the DC/DC will be easily burnt and damaged. Can you help to check what's failure scheme for this phenomenon? Is it expected behavior for our device? Thanks.

Part Number: UCD90160A

Hi all,

In the design, customer set SHUT_12V_B to 12V output high enable and controls DC-DC power-on. SOCPL_SHUT_12V_REQ_3V3 is 12V power-on trigger signal, "high" is enable.

When verifying on the Demo board, when SOCPL_SHUT_12V_REQ_3V3 is high. After 12V enable is turned on, if SOCPL_SHUT_12V_REQ_3V3 is set low again, it is found that the 12V enable signal is always on and cannot be turned off to power off 12V.

Part Number: TMS320F280049C

We are currently developing a BLDC motor driver with DRV8353RS-EVM and F280049C MCU.

We are facing repeated failures of the DRV8353RS chip when trying to run the board with the motor connected.

Most of the time the gate driver failure occurs and the gate pin of one of the Mosfet gets damaged.

The test setup consists of

1. DRV8353RS-EVM board
2. LaunchXL F280049C microcontroller card
3. A custom daughter card to connect these two boards
4. BLDC motor (R 0.245 ohm, L 30uH, 2pole, 80,000 rpm motor)
5. 24V 5A CV/CC power supply.

Configuration settings

1. PWM Carrier: 100kHz center-aligned HRPWM
2. 6 step control (Bipolar commutation)
3. 6 PWM IN Mode
4. Gate Drive current 150mA/300mA, tdrive 1us (taken from FOC example used in GUI)
5. Deadtime (50ns in DRV, 45ns in the controller)
6. OCP Mode (cycle by cycle) / 50us retry time
7. VDS OCP set to 0.100V and deglitch time of 2us
8. SEN OCP set to 0.25V (8.33A with 0.030 ohm shunt)

Board Modifications

1. Changed shunt resistors to set current trip at 8.33A

When we try to accelerate the motor by giving a higher PWM duty cycle, and the current crosses 8.33A. The gate drive in one of the phase fails.

The SPI status register shows Gate Drive Failure (GDF) and one of the MOSFET (VGSxx) failure.

We have tried similar PWM inputs/overcurrents in DRV8301-HC-EVM. It never failed.

We have checked the PWMs and found no cross conduction/shoot through happening.

In a recent case, the Failed driver gives 3V continuously to the MOSFET and the charge pump voltage is also around 3V.

The Failed Mosfet gate to source resistance shows (Mosfet in still in the board) around 91 ohms. (good one shows >100k)

Kindly suggest any modifications/workarounds we can to mitigate the driver failure.

Part Number: TPS54160

Hi,

As shown in the datasheet, "the COMP pin voltage will increase and decrease as the output current increases and decreases." 

And i did some test,shown below.

Image may be NSFW.
Clik here to view.

And in these two tests, Vcomp is aligned with the datasheet. Iout increase, then Vcomp increase.

Until i see these in the datasheet: "The transconductance (gM) of the error amplifier is 97 μA/V during normal operation". So the output of the error amplifier, should be 97*0.795=77uA. Test 1 and test 2 should has the same EA output.

Here comes my question: 

1. Why does Vcomp change while the output of the EA doesn't change? Is this relevant to the outside frequency compensation?

2. What in the output of EA? volt or current? 

3. If Vout fixed, Vsense fixed, then the EA output should fixed. Am i right? And can i say the resistor divider outside the Vsense controls the Vout? and the PWM comparator controls the Iout?

Also, If you have some learning resources, you can send it to me.

Thanks.

Best regards

Team,

Customer is trying to make the firmware SW update (see pictures 1/2/3 below):
    -Win 8.1 PC.
    - run installer as ADMIN
At some point the USB2ANY need to be disconnected/reconnnected and BSL button pressed.
Doing this does not seem to update the firmware.
How can it be fixed?
Do we have a video or guide showing the exact sequence?

Part Number: AM5718

I am using AM5718 IDK EVM,and ti-processor-sdk-linux-am57xx-evm-05.03.00.07. I have enabled McSPI2 and have done McSPI transfers successfully .

I have a small issue.

I modified am57xx-idk-common.dts as given below to enable McSPI2:

-------------------------------

&mcspi2 {
status = "okay";
ti,pindir-d0-out-d1-in;

mydev@0 {
compatible = "rohm,dh2228fv";
spi-max-frequency = <1000000>;
reg = <0>;// Chip select 0
spi-cpol;
};
};

----------------------------------
/dev/spidev1.0 is created in this case and I am not able to open it.

/dev/spidev1.0 and /dev/spidev2.0 are created if I enable both McSPI1 and MCSPI2 as given below:

-------------------------------------------------------------
&mcspi1 {
status = "okay";
ti,pindir-d0-out-d1-in;

mydev@0 {
compatible = "rohm,dh2228fv";
spi-max-frequency = <1000000>;
reg = <0>;// Chip select 0
spi-cpol;
};
};
&mcspi2 {
status = "okay";
ti,pindir-d0-out-d1-in;

mydev@0 {
compatible = "rohm,dh2228fv";
spi-max-frequency = <1000000>;
reg = <0>;// Chip select 0
spi-cpol;
};
};

----------------------------------------------------

In this case, I am able to acces /dev/spidev2.0 and do McSPI transfers successfully.

I want to use only McSPI2. Can you tell me how to add a single node mcspi2 in DTS and make /dev/spidev2.0 enabled ?

Part Number: LM98620

Hi,

   In my project i am using lm98620.Regarding this i have 2 questions.

1.I am updating the gain value through spi communicaion(0x08,0x0C for Red channel) and enable red channel gain in 0x03 Register.After read the register(0x08 and 0x0C) through spi it's showing 0 value only.Apart from this,is there any  setting for gain adjustment?

2.I am getting the camera waveform with up and down oscillation.So what are the parameters or registers or Signals should i check?

                             Thanks in advance.

I checked the help it is saying to change proxy settings. I am not getting how to do that.

Another thing is with GUI Composer it is not showing XDS510 Emulator option when we try to connect target board(TMS320F28335).

Is that not supported by GUI Composer?

Please help with the issue.

Thanks,

Part Number: TLV320AIC3262

Hi expert

My customer design this part and they have one question about the MEMS microphone start-up time which is connected to TLV320AIC3262IYZFR.

• DMIC_SCL is connected to IC's H8 pin(output)  
• MIC_P is connected to IC's G3 pin (Input)

And when 3262 sent the first clock (DMIC_SCL) to MEMs microphone, 3262 should wait about 100ms then received MEMs' feedback- MIC_P valid output data.

So the customer would like to know is 100ms acceptable or not? Is it too long for our chip?

And do we have the specification for this response time?

Part Number: CC1352P

Hi,

I'm using CC1352R1(peripheral) REV C and CC1352P1(central) REV E. When I run the peripheral and central examples from the sdk on respective launchpads(V2.4 for peripheral and V3.1 for central), the peripheral is getting disconnected. But it seems central device "doesn't know" about the disconnection as it is not printing "device address is disconnected" which is in GAP_LINK_TERMINATED_EVENT case. It seems this is the only way the central device knows that the peripheral is disconnected.

Is it a bug in the stack? If not, how to overcome it?

Part Number: AM5708

This is related to topic: https://e2e.ti.com/support/processors/f/791/t/639301

We have migrated from the 4.4 TI linux kernel to the newer 4.19.79+ kernel which is supported in the latest SDK release for AM57xx SoC.

Using the new U-Blox driver for a 4.20+ kernel on our platform, we see that the driver doesn't boot. According to U-Blox support this could be caused by SDHCI driver handling interrupts & clock:
"The problem is most likely related to SDIO IRQs from the module being lost, because the host switches off the SDIO clock between transfers, instead of keeping it running or switching to 1-bit mode as required by the spec. We've seen this issue on other TI AM57xx platforms as well with newer kernel versions that use sdhci driver instead of the older hsmmc." 

Is there some way we could keep the sdio clock alive between transfers?
We are executing the following prior to loading the module:

echo on > /sys/class/mmc_host/mmc2/device/power/control
echo on > /sys/class/mmc_host/mmc2/power/control
echo 1 > /sys/devices/platform/44000000.ocp/480ad000.mmc/mmc_host/mmc2/rescan

But it isn't sufficient..

Below the full boot-log:

Thanks in advance,

Tool/software: TI C/C++ Compiler

Hello!

We have observed a big increase of code size when moving from using CGT 7.3.23 to CGT 8.3.4. In both compilations, we are using the same compiler flags:

--mem_model:data=far -pdse9 -pdse48 -pdse190 -pdse225 -pdse262 -pdse849 -pdse994 -mi1000 -mv6600 -mo --strip_coff_underscore --disable_push_pop -o3 -ms0 

One reason why binary's size is increased is that compiler adds unnecessary NOPs to the code, to align fetch packet boundaries.

And that is visible when it is using so called compact instructions,  i.e.16-bit op-codes

And an another problem which is visible, which also adds unnecessary NOPs, which is NOT visible with CGT 7.3.x compilations either:

1081ec50   0fff6410           B.S1          odo_send_helper (PC-1248 = 0x1081e760)  -> here we call "odo_send_helper" and the actual "return" is done inside odo_send_helper
1081ec54       71f7           LDW.D2T2      *++B15[2],B3
1081ec56       8047           MV.L2         B0,B4
1081ec58       1313           MVK.S2        16,B6

1081ec60   00000000           NOP  

And the compiler generates an extra return symbol + NOPs, which is never used!!

Would you be able to explain why the new compiler generates such unoptimal code?

Second problem is that we are seeing unnecessary symbols (visible in the code but used nowhere) in DWARF structure:

0x00000000 0x00000004 poolIdPrivate
