Part Number:TIDA-00281

Hello,

I am looking for a reference software for the design TIDA-00281, I have found tidcbd2 file, which includes some files from the motorware at path:

E:\sw\modules\hal\boards\TIDA-00281\f28x\f2802x\src, as per path it can be observed that it related to motorware path, but inside the

path:C:\ti\motorware\motorware_1_01_00_18\sw\modules\hal\boards, there is no such folder name as a TIDA-00281.

CCS: CCS6.1 output file issue

$
0
0

Tool/software: Code Composer Studio

Hi,

Generated application software ( release bin)  using CCS3.1 and loaded into DSP5509A. DSP5509A transmits McBSP data at the rate of 20MHz  to OMAP L138 . DSP 6748 (OMAP L138 DSP6478)  receives data successfully without any frame missing issues.  The same application  software generated CCS6.1 ( release bin) and loaded into DSP5509A but the data frames are missing  in the OMAP DSP6478 side.

We did observe that release bin generated from CCS3.3  file size is 127KB and CCS 6.1 file size is 124KB. We did compare all the memory model, compiler, linker settings and looks like all are identical between CCS 3.3 and CCS 6.1.

Please  note that the same behavior ( missing data frames) occurs on CCS6.2, 8.2 as well.

Question is why CCS 6.1 generated release bin missing data frames but not in the CCS 3.3 generated bin file. Please help us to solve the problem.

Thanks,

Part Number:BQ24725A

Hi,

I'm using BQ24725A. Sometimes the voltage on HIDRV will become high. This will cause the IC to enter the protection status. Please see the attachment for details.

My question is: Why the voltage on HIDRV will become high, but not many pulses?

Thanks.

Hello all,

                                 I'm working on a custom board based on am335x ice v2.I want to toggle gpio pins at 12MHz.I have learnt that this is not achievable with cortex a8 because of the slow l4 interconnect.We have decided to use PRU cores for achieving this.I want to use Togglegpio application which comes with the SDK.But after booting im not able to see "/sys/class/remoteproc/remoteproc1"  and "/sys/class/remoteproc/remoteproc2" in the sysfs entry.However there is remoteproc0.How to enable remoteproc1 and remoteproc2?

Part Number:TL3116

Hello,
customer want to measure a 2A current high side at 110V. He is looking for the INA293 but needs an alert/latch pin like in the INA301. Therefor wants to use the TL3116 which has an latch output. The TL3116 is very limited. Can you share a truth table to understand the exact working of this IC. Is there any any application note?
Also please let me know if you have other current shunt recommendation.

LMZ10501: The probability of Vout's soft start time too long and the output voltage wrong

$

Part Number:LMZ10501

Hi team,

My customer use LMZ10501  but it face some issue that would like to consult with you..The schematic is as below.

There are several assembly board that have the below problem after start up. 

Normal:(CH1:EN, CH2:Vout)

Issue1: 

It need to take a lot of time (several seconds) to be operating voltage after starting up.

Issue 2:

Output voltage is unnormal after strating up.

.

We have done some resoldering for the assembly board by hot gun air and the behavior will change into different case with possibility.

May I have your comment and suggestion to prevent the failure case happening possibility ? Thank for your help.

TPS65987EVM: how to increase 5V to 20V transition time @ 20V PD contract in USB-C

$

Part Number:TPS65987EVM

Hello,

I use TPS65987EVM to deliver 20V/5A.  When 20V PD contract happens the voltage rises from 5V to 20V. How can I change this rise time? The problem is that we observe high inrush current, so  we would like to increase the rise time to make 5V to 20V transition slower.

Thanks and Regards,

Natasha
