Part Number: CC2530
Hello Team,
I am using cc2530 Zigbee module and also able to flash successfully.
But in some case after some time my zigbee is not working. If i will flash once again then zigbee will work.
Can you please tell what are possible way of zigbee firmware crash?
How can we check zigbee firmware is proper?
Thanks

Hi guys,
I'm trying to use OSAL timer functions to trigger a function over specific intervals.
as I read in z-stack doc there is event_id in OSAL timer function's input elements.
my question is how can I generate my own event and how to map a function to that event
Good morning,
I need to boot from a NFS filesystem to a DM368 processor.
On a linux machine I extracted my filesystem to: /tftpboot
then I added in /etc/exports this line:
/tftpboot *(rw,no_root_squash,no_all_squash,sync)
then I executed the commands:
sudo /usr/sbin/exportfs -av
sudo /etc/init.d/nfs-server restart
then I switched to the DM368 board and gave these commands to UBoot:
DVR: set bootargs mem=38M console=ttyS0,115200n8 root=/dev/nfs rw nfsroot=192.168.2.11:/tftpboot,nolock ip=192.168.2.222:192.168.2.11:192.168.2.1 davinci_enc_mngr.ch0_mode=ntsc
DVR: boot
but I get this error:

Hello,
Have a question on configuring the ADC channels (ideally all of them, now we are using only 10) to be in continuous conversion mode as the fastest possible speed. Here is my application.
I am monitoring the analog values on the these channels and taking actions on them in the main thread. In the main thread I wake up every 20 uS look at the converted values and process them. At this time granularity I am assuming I am getting the latest values minus the conversion time. Looked at Wiki and other resources could not find anything relevant. I have done something on my own modifying a F2807X example code. Don't think it is working properly.
Any help/pointers is appreciated.
Thanks.

Here is my "requirement"
Part Number: TLV9061
Dear Team,
May we know what estimated CMRR min is when VS = 1.8V, Vcm = -0.1V to 1.9V?
Is the CMRR min spec with above condition similar to VS = 5.5 V, VCM = –0.1 V to 5.6 V?
Thank you!

Hi,
We are trying to copy a file present in the remote device to local device using "scp" system command over wifi mesh. This command fails inconsistently when fired from our application.
Attached are the kernel logs when copied using a script.
Also tried running tcp server for transferring bytes but in that case partial bytes are transferred. (logs attached as TCP_CLIENT).
Mesh network is running on 2.4 GHz, Channel 6 and in "n" mode.
We are using old Linux kernel build from year 2016 that has limited utility options. Please suggest a reliable mechanism for file transfer over mesh accordingly.
Thanks,

Part Number: DRV8305-Q1EVM
Hello,
A few days ago I received the DRV8305Q1-EVM. I am trying to understand how to work with the InstaSPIN-FOC MotorWare GUI (or with the CCS) for my requirements.
I need to actuate a Point To Point move with a constant velocity. How could I actuate this motion? Which LAB should I use for such a motion?
If I need a very accurate position for the velocity change ( from 200deg/sec to -200deg/sec) , could I connect a 18 bit encoder to this board? Does the TMS320F28027F have encoder inputs?
Thanks for your help!

Part Number: ADS1293
Hi,
I'm using the ADS1293 EVM board, however with an external Teensy 3.6 and not the on board Microcontroller (as the ADS1293 is only one part of another, larger project). Using the register config for a 3 channel ECG and attached ECG simulator I can get nice output data (stream reading the data loop register), until all of a sudden the DRDYB signals stop coming. I've confirmed this with an oscilloscope, screenshots attached (I hope they uploaded correctly). I'm not doing anything in the code that should stop the device and I'm pretty sure it was working in an earlier test. I can still see very small spikes on the DRDYB pin in the same frequency as the Interrupt signals were coming in earlier. The durations for which I do get the interrupt singnals are random. I have confirmed that nothing is wrong with the evaluation board in general (using the ADS1293EVM test software).
I can not see anything relevant in the error registers once the data stops coming (or before for that matter, as I'm also interrupting on the Alarm pin):
ERROR_LOD: 0x00
ERROR_STATUS: 0x00
ERROR_RANGE1: 0x00
ERROR_RANGE2: 0x00
ERROR_RANGE3: 0x00
ERROR_SYNC: 0x00
ERROR_MISC: 0x00
If anyone has an idea that could help? For now, I'll read out all other registers to see if anything is amiss there...
Thank you!

Part Number: IWR6843ISK
Hi
I am using IWR6843ISK for mapping and navigation using autonomous_robotics_ros lab from the industrial toolbox version 3.6.2. and I am using SDK version 3.2.0.4 for the same.
I am done with flashing the device using uniflash.
Now I am trying to obtain a point cloud for mapping.
Firstly, the .cfg files in the toolbox are not working and giving errors. I went through the forums and found a .cfg file that shows point cloud but I am not able to understand what does it represent.
I just shows some random point cloud.
Please share the correct .cfg file for the autonomous_robotics_ros using IWR6843ISK.
As shown in the demo for the same lab , the point cloud seems very accurate but it is not the same in my case.
Please reply soon.
This is the .cfg file I'm using with my device.

Part Number: LAUNCHXL-CC1352R1
Hi,
I have an old LaunchPad of cc1352R1 (rev c) and I have my own custom board using the new cc1352R1 (rev e). I connected the debugger on the old LaunchPad to burn the firmware on the new custom board and I didn't encounter any errors. I tried the simple peripheral app and project zero to check that the BLE is working fine. I tried using 3 BLE mobile apps to establish a connection but it has been always a failure.
It keeps telling me "connecting to the peripheral" and after around 20 seconds, it tells me "Timeout Connecting fail from the peripheral". I also tried TI's sensor tag application but it didn't connect to it.
Can anyone help?
Note I am using simplelink_cc13x2_26x2_sdk_3_20_00_68 and CCS v9.1.

Part Number: TIDA-00704
Hi Experts,
Tried to design a charger using TIDA-00704 (w/o MCU) for 28.8v, 20Ah battery,
I have two questions
1. How can I control the output voltage and current of TIDA-00704?
via FB pin on U8 or via Vref and Iref of U5 and how to use these pins?
2. Need a troubleshooting manual or checkpoints for TIDA-00704 as it stops charging the battery earlier it starts charging with 31v, 10.5A,
tried adding a FB of 200mV to 3v for charging the output voltage.
Part Number: TMDS361B
Hi
I am laying out a board with a TMDS361B HDMI switch going to a TFP401A HDMI receiver. The 2 ICs have their corresponding pins in reverse from one another.
On the TMDS361B reference, the output went to a HDMI connector that was attached to the bottom side of the PCB and connected using vias.
Is it possible to route the traces like what is shown in the image below? Because of mounting restrictions, I don't think there will be space to have any ICs or connectors on the bottom of the PCB.
If the shown method is not recommended, do you have any other recommendations?
Thanks
hello everybody ,

Hi,
I would like to know if I can embed the Device Tree in SPL (u-boot-spl.bin or MLO).
Use Case: SPL doesn't have clear idea of the DRAM configuration which is present in the Device Tree and is processed in U-Boot stage.
I would like to have SPL know the DRAM configuration, hence I want to know if I can embed some minimal devicetree in SPL to achieve the same.
Thank You.

Part Number: TLV320DAC3100-Q1
Hi team,
I have a question about power up sequence of TLV320DAC3100-Q1.
I designed all the power rail to 3.3V (SPKVDD, HPVDD, IOVDD, AVDD) except VDD=1.8V, and configured to power up all rails at the same time.
It is not exactly same as the recommended sequence in the datasheet.
Is there any concern if I power up all the rail at the same time?
***I found the other thread asking about the power up sequence of this device
and it concluded that as far as /RESET is held low until VDD power up and be stable, POR works fine and there should be no problem.
If I release /RESET signal at the very end of power up, the power up sequence of each rails don't care?

Part Number: BQ25713
Hi TI team,
I have two questions
① Our system incorporates DC source and 4-cell battery. But it will not have charging function. Either
(a) supply from battery
or
(b) DC + battery (no charging)
My question is what is the maximum voltage setting for (b)?.
In the datasheet 9.6.4 MaxChargeVoltage, it says max voltage is 19.200V but is this only applies during charging?
While the 9.6.5 MinSystemVoltage says the max voltage is 16.128V.
During(b), we want to set at approx 17V.
② Is there any way to implement back-to back FET between battery and VSYS? We want to reduce leakage current as much as possible when system is off.
Thank you!
