Part Number:TDC1000-TDC7200EVM

Hello,

    I have interfaced tdc1000 with arduino, where I am facing a shortage of pins. So I had a doubt whether both reset and enable pin are needed for programming the tdc1000 or can I just use enable pin alone for programming and for measurement?

BQ40Z50-R2: Will not charge unless there is SMBus communication with the part.

Part Number:BQ40Z50-R2

Hello,

I presume the problem we are observing is related to a flash setting, however, we are at a loss to identify which one.

Our battery pack design functions just fine; except the battery will not charge at all unless there is SMBus communication with the part.  As soon as the SMBus is disconnected, or communication stops, charging stops.

NR=1 and the charge FET is configured to be ON in sleep mode.

Thanks,

Hi Team C2000,

I'm looking for the Altium Schematic and Layout Database for the C2000 DIM100ExperimentersKit docking station.. The info in ControlSuite is partially there.. a schematic file (but no board layout info).  But.. the schematic file (C:\TI\controlSUITE\development_kits\~ExperimentersKits\DIM100ExperimentersKit-HWdevPkg_v2_0\R3\USB-DockingStn[R3].sch ) is actually empty.

Thanks, Merril

BQ76PL455A: How bq76PL455 communicate to MCU?

$

Part Number:BQ76PL455A

Dear Sir/Ms.

The customer sample board was returned, and I wanted to connect to TI's software test, but I couldn't connect it.
Q1: When using the DEMO board, why is SW2 (1 is ON and 2 is OFF) connected to communicate with the computer (such as the accessory DSC_1178.JPG). SW2 (1 is OFF, 2 is ON) Can't connect (eg attachment DSC_1179.JPG)?

Q2: Is it necessary to put this circuit on our board, or choose one of the MODEs on our board to be able to operate normally? If there is no such line on the customer's board, what effect will it have?

Best Regards,

Kami Huang

Part Number:CC2650

Hi everbody,

I'm very new in this flied. I want connect my Sensortag CC2560STK about Mqtt with my Raspberry Pi 3 B this runs with Raspbian Strecht.

For the connection I use an openlabs Modul openlabs.co/.../Raspberry-Pi-802.15.4-radio who is connectet to the GPIO from the PI, I creat an lowpan.

I have cange the cc26xx-demo for send periodic UDP its works well.

c = udp_broadcast_new(UIP_HTONS(1234), NULL); 
tcpip_poll_udp(c);
	PROCESS_WAIT_EVENT_UNTIL(ev == tcpip_event);
	uip_send(send_data, sizeof(send_data));

And in the Project.conf I change:

/* Change to match your configuration */
#define IEEE802154_CONF_PANID            0x0023
#define RF_CORE_CONF_CHANNEL                 26
#define RF_BLE_CONF_ENABLED                   0


#define NETSTACK_CONF_RDC nullrdc_driver
#define NETSTACK_CONF_MAC csma_driver

Now I want to connect to MQTT with this settings. I have change the settings from project.conf of the Project cc26xx-web-demo and the mqtt-client.h. I have a mosquitto broker runs on PI with the Host fd28::1.

But it doesn't works. I start wireshakr on the PI but I doesn't see anything. only what I see is the Message from Sensortag  "ICMPv6"

Have anybody an idea what I do wrong or have an example for me? Or a example for a TCP connection?

Salute

TMS570LC4357: Cache ECC and ESM Group 3 channel 9

$

Part Number:TMS570LC4357

Hi all,

I am trying to understand how the Cache ECC works in the Cortex-R5F, coupled with the TMS570LC and the ESM, in order to be able to properly manage uncorrectable ECC errors occurring in the system.

In the Cortex-R5 documentation, it is written that the cache can be configured as "Do not generate aborts, force write through, enable hardware recovery" (see chapter 8.5 of Cortex-R5 TRM).

When configured this way, uncorrectable ECC errors in cache are silent and data is reloaded from the L2 memory (in fact, these are not uncorrectable errors...?). As the region operates in write through mode, no line can be dirty so no data in cache can be lost.

That would be perfect to make uncorrectable ECC errors in data cache invisible to software and to increase the system availability (note: in our system, ESM nERROR pin is routed to the system validity logic.).

But then I saw that in the ESM, group 3 channel 9 is generated when "data cache data/tag/dirty RAM fatal errors" are signalled by the Cortex-R5 through the Event bus, that would make the nERROR pin go in fault (in our system, this makes the system unavailable).

Can anyone confirm this statement or explain to me if the ESM group 3.9 is not triggered if the cache is configured "Do not generate abort, force write-through, enable hardware recovery"? As far as I understand, the event bus of the Cortex-R5 will signal all events, regardless of the configuration for aborts, but I'd like the experts to correct me if I'm wrong.

In the case the cortex-R5 will signal the event regardless of the cache abort configuration, is there a way to prevent it to be signalled on the event bus (like an event bus events configuration register)?

I was looking for an configuration of the Cortex R5 and TMS in order to make cache ECC errors silent, but with the nERROR pin connected to our system validity logic, is there one possible?

Thanks.

TPA3131D2EVM: Quiescent current not in line with datasheet info

$

Part Number:TPA3131D2EVM

Hi all, 

After doing some current consumption tests on TPA3131D2 eval board, I have measured a  quiescent current that is not in line with the numbers on the datasheet.

The quiescent current was measured using the eval board with no load connected to the output. The result was 32mA with 7.4V PVCC.

According to the datasheet, at 7.4V PVCC with no load or filter, the quiescent current typically is 16mA, half of what we have measured.

Last revision of the datasheet was in Jan 2015, I don’t know if numbers have changed in further revisions.

In the datasheet there is no info about max values but usually if no info is provided, max values is about 5-10% higher than type values at room temperature. 

Could someone confirm to me the datasheet values or point me to the right direction?

Regards, 

Fran

TMS320F28335: Power sequencing & the reference design SLVR332A

$

Part Number:TMS320F28335

Hi,

The data sheet and the related reference design (slvr332a.pdf) using 2x LDOs suggest to power the 1.9V core (VDD) before the 3.3V(VDDIO) in order to prevent glitching.

If using different LDOs as suggested in the reference design, is it ok to use a LDO "power good" output instead of the voltage rail (as mentioned in the slvr332a.pdf) to drive the transistors? This is in order to obtain a clean transition at the input of the transistors and also make sure that the 1.9Vcore (VDD) output is stable before powering up the 3.3V (VDDIO)?

Or 

Is it a explicit requirement to keep the core 1.9V core (VDD) & 3.3V (VDDIO) within 0.7V of each other during initial phase of power up?

Best regards,

Dhaivat


TPS54620: Vout is unstable

Part Number:TPS54620

Hi Team,

My customer is using TPS54620 at 12V to 1.1V application. He encountered output voltage is randomly unstable issue.

1. Below is customer's SCH.

2. Below is the unstable voltage waveform.

Usually, it happens at power up at room temperature, once the device get warm and customer reset TPS54620 by pulling down then pulling up EN pin, output voltage become normal.

If output voltage is stable, using freeze spray to cool down the chip that can reproduce voltage unstable problem.

Could team help to review the SCH and this issue, then please provide us the comment. If need any other information or experiment, please let me know.

Thanks very much.

Part Number:OMAPL138B-EP

For the OMAP L138, is it fine to swap the DDR data lines within a byte for routing purposes?

Do the LSB data lines for each byte (eg: D0) need to remain the same?

I plan on using the micron MT46H64M16LFBF-5 IT:B mddr device and I am waiting on confirmation that it is JESD79-2A standard compliant.

Has this device been tested with the OMAP L138?

Thanks,

Hi , 

We are using AM5728 EVM with latest TI Android SDK. 

We were trying to run a html page that has some WebGL code behind it. The code runs fine on chrome browser in a desktop.

We are getting WebGL support missing errors and all gl calls returning null and WebGL support NOT AVAILABLE on TI EVM & Extended Monitor. Root cause, we are not able to set values to textures within WebGL because WebGL is NULL, gl reference is not available in WebUI running on extended monitor.

Any help in this direction is appreciated. 

TPS7A47: reliability at high voltage operation

Part Number:TPS7A47

Dear Sir

Is there a problem with the TPS7A4700 operating at high voltages? We have used approximately 3681 of these devices across 26 boards mostly with no problems when it is used to produce less than about 8Volts output. When it is used to produce 20.5Volts we get some failures during test and, very embarrassingly, some failures in field.

Similarly is there a problem with the TPS7A4701 operating at high voltages? We have used 218 instances across 7 boards. On one board where it is used to produce 24Volts every single instance has failed during test.

Please can you help?

Thanks

John
