Part Number:TMDX570LC43HDK

Tool/software: Code Composer Studio

Hi everybody!

I recently got an evaluation board for the TMS570LC43X processor and I've been trying to build the lwIP demo that is here.

What I did was:

- import the project on CCS using Project/Import project and then looked for

C:\ti\Hercules\HALCoGen EMAC Driver with lwIP Demonstration\v00.03.00\TMS570LC43x\Build-TMS570LC43x

- then, after hitting the Debug button, the compilation starts but it gets stuck when it reaches this message:

Part Number:LM5170-Q1

If 4 modules are operating in parallel, how this IC handle the load balancing on each module?

Is there any application note or details on this?

Part Number:DP83867IR

Hi 

I'd like to know the configuration of Mirror mode.
I know that Mirror mode can be enabled/disabled via strap or register configuration.
But it seems that "After Mirror mode is enabled once, it can't work properly if Mirror mode is disabled after that".

The port connections of my customer board is not mirroring. So, they usually use it with Mirror mode disabled.
But, at first, Mirror mode is enabled via strap. And then, they changed Mirror Mode register configuration using MDIO. As a result, it doesn't work.

====================
1. Mirror mode is enabled via "strap", 
2. Mirror mode is disabled via "register configuration" using MDIO.
=>NG: Link is established. But there is no data on RGMII RX signals if there are some "Receive activity". (LED2 is lighting)

====================
1. Mirror mode is disabled via "strap",
=>OK! no problem.

I checked it using EVM. I confirmed the same phenomenon happens.
So, I understand that  "After Mirror mode is enabled once, it can't work properly if Mirror mode is disabled".
Is my understanding correct? Or we need to config any other register when Mirror mode is changed?

Of course, I think Mirror mode should be disabled via strap for this board.

Best Regards,
Taka

Part Number:CC3100

We have a cc3100 based product which connects to google servers (android.googleapis.com)

This was working fine for a long time until a few days ago.

We started getting error -340 on the SSL connection.

The SSL setup is :

method.secureMethod = SL_SO_SEC_METHOD_SSLv3_TLSV1_2;   

cipher.secureMask = SL_SEC_MASK_SECURE_DEFAULT;

sl_SetSockOpt(gSockID, SL_SOL_SOCKET, SL_SO_SECURE_FILES_CA_FILE_NAME,GOOGLE_CERT_FILE, strlen(GOOGLE_CERT_FILE));

Ive tried to select specific ciphers. Also tried different certificate files, using the exact same one which works with a PC curl application. What I see is that the first sl_connect takes a long time and then fails with -340. Repeated attempts fail immediately with the same error.

Part Number:CC2650STK

I'm working on a project in which we want to scan (observer mode) BLE beacons MAC address and RSSI using a cc2650 sensor on real-time.

I checked simple_central_audio_receiver project (for cc2650 launchpad) and saw that it have problems to do properly on sensortag.

I was wondering if someone could help to find a sample code to do it simply.

Thanks in advance.

Part Number:RM46L852

Tool/software: Code Composer Studio

Hello All!

I was trying to use the RAND() function in stdlib.h and rand.c in my code but the resource lock halts everything and it stalls there.

Properly moves into rand.c and in the check:   #if !defined(__TI_USE_TLS)        decides it is not defined and attempts to execute:

                    __TI_resource_lock(__TI_LOCK_RAND);

Stepping through the debugger it halts on this line.

_mutex.h contains the details on this resource lock call.

I have no idea why it is halting here. I've never called RAND on a micro-controller before, so I don't know if such a call on this hardware is even valid.

I also don't know if the fact that I'm doing it on a Hercules with two "locksetup" cores has implications of its own.

Part Number:CC3200

Hi, I use the CC3200 launchpad rev 4.1.

I use the HTTP server example from SDK 1.2.0 and Service Pack 1.0.1.6-2.7.0.0.

// In main.c, start OS Scheduler, I do not use RTOS
    //
    osi_start();

    while (1) // No WFE or WFI
    {

    }

I expected to use the WFE (Wait For Event) or WFI (Wait For Interrupt) in the while loop to save current consumptions.

In my case, I changed the example a bit; I use both Wi-Fi and PWM.

I wish the CC3200 to sleep in the while loop and wake up when radio events or PWM events occurs.

Is there an example to wake up when using Wi-Fi?

The Wiki explains the RTC wake-up. However, I cannot determine whether the RTC wake-up is related to my desire above.

Dear,

Regarding application of TPS65381, I have several questions and hope to get support from your side:

1. How to use NRES? Can it be connected directly to MCU? Is there pull-up resistor needed?
2. As we understand, DIAG_OUT is output of diagnostic signals selected by SPI, is it right? If choosing analog signal as output, how to select low-pass resistor and capacitor, what frequency need to filter out?
3. Is RSTEXT used to set delay time of NRES by adjusting resistance? How to select the resistor?
4. If we decide not to use CAN wake up function, how to configure CANWU pin (floating or pull down)?
5. If we choose 5V as sensor supply voltage, should VSIN be connected to VDD6? Should VTRACK be connected to VDD5? How to choose the resistor for VSOUT1 when we want unity gain feedback?
6. If we want VDD1 to be 1.2V, how to choose resistor for VDD1_SENCE? How to calculate it?

Hello.

I am using CCS v 6.1.2

I am trying to change theme or colors.

Only changing to dark theme is available. I can't use other themes(from eclipsecolorthemes.org) and change detail color of c++.

When I use original Dark theme, I almoe can't see from" #else "  to "#endif" texts because of its color.

Is there no way to change color of details?

Thanks & BR

Part Number:PCA9555

Dear,

Our customer have two problems when using PCA9555, please help to analyze:

1. They use PCA9555 to scan keypad, after several restarting ( restarting the whole system instead of PCA9555 and initializing PCA9555 every time ), keypad scanning will be false. The schematic as follows.

2. The standby-current consumption is 1 uA max in datasheet, but the current they tested actually is about 470 uA. So what configuration should we do to reduce the current ?

I will appreciate that if you rely to me, thank you !

Part Number:TLE2022A

Tool/software: TI-RTOS

Hi

We are considering TL2022A and we had a question.

There is a parameter of KSVR(Supply-voltage rejection ratio)  which offers MIN 98dB in full range.

Is this min 98dB spec always applicable even if supply ripple frequency is swept?

BestRegards

Part Number:TPS54327

Hi all

Would you mind if we ask TPS54327?

<Question1>
The value of output capacitance is 22uF upto 68uF on the datasheet.
How much is the maximum value?

<Question2>
In relation to <Question1>, for example, there is 10uF or 22uF ceramic cap in the subsequent stage circuit.
There are three subsequent stage circuits,  10uFx3=30uF.
In this case, does it(ceramic cap in the subsequent stage circuit) include total amount?
Usually, We guess that the total amount(output cap value) includes the subsequent stage circuit.
In this case, when we use Aluminum cap(large ESR) at the subsequent stage circuit, is it is no matter??

We guess that it depends on distance(impedance) with the subsequent stage circuit.


Kind regards,
