TPA3111D1-Q1: Amplifier external load diagnostics
Part Number: TPA3111D1-Q1
Hello,
I read the Class-D Amplifier External Load Diagnostics application ,and was wondering if it suits my application.
Instead of the TPA3111D1-Q1, I have a power amp class H high power 2500 W, Its load is away from it from 1 to 2km .I want to be able to detect an open circuit, this diagnostic system need to work also when the load is used (since I can't know when the load is working or not).
Since the current is high, I was thinking about using a voltage and a current sensor for the input of the external load diagnostic.
Do you think this solution can work for my application? what are your recommendations ?

AM3358: SGX 2D acceleration issue
Part Number: AM3358
hello :
I have changed to am335x newest 06.01.00.08 linux sdk ,I want to use the 2d accelaration
because there is only one app run on my device and full screen, so I run /etc/init.d/weston stop
I export QT_QPA_PLATFORM="eglfs"
when I run my xwidget demo,and It show cpu is 87%,
when I run lsmod ,result is as following:
root@am335x-evm:~# lsmod
Module Size Used by
pvrsrvkm 397312 2
When I kill my xwidget ,then
root@am335x-evm:~# lsmod
Module Size Used by
pvrsrvkm 397312 0
So I confirm that gpu is working , Because when my program run ,some module use the pvrsrvkm module.
but problem is that why cpu rate is so high 87%.
Can you help to analyze why the small demo cpu rate so high ?
There is other program which also use 2d qt5 opengl widget ,but when use am3358 the cpu is always 100%,but the same program run on device with imx6q
with gpu on, the cpu is very low,10% cpu.
Why? How to enable the 2d accelartion?
I attach my xwidget demo.Can anyone help?
Best regards

CC2640R2F: ICall_malloc return NULL when there is still enough free size
Part Number: CC2640R2F
Hi team,
We use CC2640R2 with SDK 3.20. We use CACHE_AS_RAM and have allocated a 6K heap. Now we meet a weird issue with Heapmem. When using ICall_getHeapStats(ICall_heapStats_t) to dump heap info , get totalSize=6144, totalFreeSize=1264, largestFreeSize=752, but when calling ICall_malloc() with a size of 166, it returns NULL.
Why is it returning NULL when there's a free chunk of size 752?
Please help clarify. Thank you.

I've observed that if Data struct defines a constructor, a compiler warning is thrown:
"warning #10210-D: creating ".esysmem" section with default size of 0x400; use the -heap option to change the default size".
It has no sense for me, it seems that compiler is inferring that heap is needed.

SIMPLELINK-CC2640R2-SDK: v2.30: UTC Clock jumping from 2019 to 2020?
Part Number: SIMPLELINK-CC2640R2-SDK
Hi,
I have used the utc_clock.c and utc_clock.h at my custom CC2640R2F board for several months now and it works. On device power up, I update the device utc time using the smart phone time. But this month December 2019, when I set to current date the year jumps to 2020. Example below.
YYYY MM DD HH MM SS
2019 12 02 00 00 00 00 - 2019 December 02 00:00:00
Becomes this below.
2020 00 02 19 28 18
Why does this happen? What could be the fix for this issue.

Am trying to play audio file using Am572x_EVM on which main core is running with ti-processor-sdk-linux-am57xx-evm-05.01.00.11.
Am using P8 audio output connector on EVM to play sound using headphone/speaker.
Able to run audio file using aplay but volume is too low. Can I know how to set frequency and amplitude of audio file to adjust its volume.
Currently am using wav file with aplay.
for example:
aplay xyz.wav
below response is comming and able to listen audio sound, but very low volume.

ADS8319: ENOB vs. Sampling Rate
Part Number: ADS8319
Hi all
My customer is using the ADS8319 at 30ksps and he has this quesiton:
On page 11 of the Datasheet there are ENOB-plots vs. various parameters, all given at fs=500ksps.
Do these numbers change when going to 30ksps ?
And if yes: Do you have plots or specs for ENOB at lower sampling rates ?

I'm using IWR1443BOOST to capture raw data with DCA1000 and doing post processing in MATLAB.
It seems there is a variation of amplitude and phase in received ADC signal of each Rx channel, which needs to be compensated.
Now, how can I measure and compensate it in my own post processing with IWR1443BOOST.

LM5117: Voltage emissions occurs under load
Part Number: LM5117
Hello!
I uses a DC-DC converter in my project. 24V to 5V, 12A, built on the LM5117PMH/NOPB chip. I used "lm(2)5117_quick_start_hv_calculator V1.5" when designed the converter.
When the converter is turned on without load, the output voltage is ideal. But when a 0.47 Ohm resistor is connected as a load, surges of the output voltage occur, which correspond to the moment of the edge of the PWM signal. And there are small emissions that occur on the falling edges of PWM. The frequency of emissions corresponds to the selected frequency of the PWM driver. Duration of emissions is about 70ns.
What could be the cause of these emissions?
What actions do I need to take to eliminate them?

Hi
We would like to design VSTART=5.5V and VSTOP=5.0V

However, using the above R10 and R11 value to do real test we see VSTART=6.33V and VSTOP=5.2V. this is different from our calculation result.
Would you help review anything wrong with our schematics below ?
Also is it required that Vin need to be > Vout + 2V ?

BQ40Z50-R2: smbus/i2c
Part Number: BQ40Z50-R2
Hi
I'm reading about ten registers from bq40z50 via smbus/i2c with an STM32L0
Once every second I perform a "read block" and everything works well for a lot of time (lets' say hours)
Then the I2C stop working and SCL is pulled down.
What I do is always the same. For example to read the device type I send
16 44 02 01 00
Then
16 44
and then I perform a read and receive correctly:
01 00 00 45
Nevertheless sometimes the I2C get stuck because SCL remains low.
Anybody can help me?
