Linux/TMDSICE3359: DP83630 Linux driver

Part Number:TMDSICE3359

Tool/software: Linux

Hello,

I have some questions about the Ethernet transceiver of DP83630:

we have used the demo board TMDSICE3359 with the ethernet transceiver of TLK1100. We have made the image of LinuxRT with SDK. We have made own board with ethernet transceiver of DP83630. LinuxRT worked at the TMDSICE3359, and this linuxRT is launched at the own board, but ethernet interfaces has not worked. DO you have the recommendations / files how I can include the driver  ethernet transceiver of DP8360 to LinuxRT. Does The firmware support the units of PRU, which has included in the actual version SDK?

 


When will SDK for LinuxRT (Processor-SDK-linux-RT-AM335X) version 3.3 available for AM335X. Or how can I adapt the solution of AM572x for AM335X (demo board TMDSICE3359)

CCS/TMS570LC4357: Problem with receiving data from sci module using polling method

Part Number:TMS570LC4357

Tool/software: Code Composer Studio

Hello!

i have a problem with receiving data through sci module. I am printing 8 bytes of data through sci at a rate of 10ms (using rti).i am using putty to view my data.i am also using the polling method to see whether there is any new 8 byte data entered through serial monitor using sciIsRxReady in if condition,all inside the while loop.On entering the if condition i am using sci receive to extract 8 bytes of data and the new data is printed in rti interrupt at 10ms rate.Unfortunately i am unable to do so.Only the initial value i assign to the variable is getting printed on putty at a rate of 10ms(rti) but when i try to take an input of  8byte data through sciIsRxReady(in while loop) im unable to receive any data. Please help .

Does sciIsRxReady return value 1 when it receives one byte of data or when it receives data through serial monitor irrespective of the length of the data obtained??

AM5728: The package covered with metal

Part Number:AM5728

Hello sirs,

Is there any processor which is covered with metal?
I think some devices (e.g. AM5728, 66AK2H14 and AM5K2E04) are covered with metal for heat sink.

CC3220S-LAUNCHXL: Adding custom GET and POST Callback

Part Number:CC3220S-LAUNCHXL

I'm working my way through the code and sort of have an idea of what is going on with the red LED.  It appears the entire process all begins at SimpleLinkNetAppRequestEventHandler().  However, it also appears the chain of events that kick off the httpGetHandler() and httpPostHandler() start in the linkLocalTask().  I don't see the link between SimpleLinkNetAppRequestEventHandler() and linkLocalTask().   I'm also still trying to figure out where to put some appropriate printf statements to see what data is actually being passed from the web server to the get and post Callback functions for the led. 

So far I've added two more URI services in http_RequestObj_t for my custom get and post and also added them to initLinkLocalDB().  I've read through swru455a.pdf which was somewhat useful but doesn't cover adding custom items to the webserver.  Mainly I'm trying to understand the processing flow for Get and Post and also where and what I should be printing to get an clearer understanding of what is in the server requests.

MSP430F4152: looking for pin to pin compatible solution with higher flash memory for MSP430F4152IPMR

Part Number:MSP430F4152

Hello,

My customer has done a design with PN: MSP430F4152IPMR which right now they found the need to have more flash memory .

they already done their board design, following this they must have a solution that is the same pinout that will not be needed for any hardware changes. 

After checking the all the components in Family Members I did not find them a decent replacement with more flash and the same pinout ,

Please you can advise me a solution, thanks in advance and regards.

DRV8872: Issue with a motor integrates capacitor and varistor

Part Number:DRV8872

DRV8872Q1 met issue in one automotive account.

Attached motor structure and parameter. 

All the test were run on EVM.

If set INx prior to VM, the motor can start-up and spin.

If set VM prior to INx, the nFault indicator LED lights on, waveform shows OCP seems to be triggered and auto-restart every 3ms.

Replaced current sensing resistor to 150mohm, 330mohm, 400mohm, 500mohm, 750mohm, 1ohm. The issue remains.

Considering the charging to capacitor leads to the OCP during start-up at high VM, current limitation should help to limit the start-up current and get the motor spin.

Wonder why the current regulation circuit seems does not effective in this case.

DAC8775EVM: Configuring Power Supply and Jumper Settings

Part Number:DAC8775EVM

After issuing a Reset (or Read All) command in DAC8775EVM software, all channels alarms are activated, as shown in the screenshot below, and can not be cleared. What changes should we make to the supply/jumper settings in order to clear the alarms?

The following are the current (default) board jumper settings*:

- An external supply of 12V is connected to J2 and all jumper settings are in default factory-setting positions for single external supply

- SM-USB-DIG supply to DVDD -  JP9 and JP11 installed while JP13 Not Installed

- Selects the DAC8775 internal reference JP10

- DC/DC Channel A to supply VPOSA and VNEGA

* Note: we are not clear on how to interpret 3-pin jumper position (1-2 "inner" vs 2-3 "outer")

Also, please note that "Clear Enable" and HART-Enable" UI check-boxes for Channels B and C seem to be "Read-Only" and can not be changed.

Thanks for your help.

66AK2H12: How can I make and install an exception handler in bare-metal code?

Part Number:66AK2H12

I want to make and install an exception handler in bare-metal (no-OS).

I want the exception handler to stores register values, and stack information, etc... and notify the exception occurrence to other cores.

When other cores receive the notification, they will stop their work(for example, executes infinite while loop).

I know we can install exception handler like below when we use Bios. 

var Exception = xdc.useModule('ti.sysbios.family.c64p.Exception');

 Exception.exceptionHook = '&myExceptionHook';
 Exception.internalHook = '&myInternalHook';

In bare-metal, how can I install exception handler? 

Thank you in advance.


Linux/BQ27545-G1: Unable to enter into unsealed mode using HDQ

Part Number:BQ27545-G1

Tool/software: Linux

Hi,

We are using HDQ to communicate with BQ27545-G1. For a requirement, I have to enter from sealed to unsealed mode through the driver code.

I tried the following code to do the same:

w1_bq27000_write(dev, 0x00, BQ27545_CONTROL_HI);

/* Read the status to check if the battery is sealed */
read = bq27x00_read(di, BQ27545_CONTROL_HI, false);
printk("%s: BQ27545_CONTROL_HI 0x%x\n", __func__, read);

/* Unseal access to battery */
if (read & BQ27545_CONTROL_STATUS_SS) {
      printk("1. Unseal the battery\n");
      w1_bq27000_write(dev, 0x04, BQ27545_CONTROL_LO);
      w1_bq27000_write(dev, 0x14, BQ27545_CONTROL_HI);
      w1_bq27000_write(dev, 0x36, BQ27545_CONTROL_LO);
      w1_bq27000_write(dev, 0x72, BQ27545_CONTROL_HI);
 }


 /* Write which register you want to access */
 w1_bq27000_write(dev, 0x00, BQ27545_CONTROL_HI);
 /* Read the status to check other flags */
 read = bq27x00_read(di, BQ27545_CONTROL_HI, false);

But this code still prints the status as sealed. I have tried different combinations of sending the code to battery guage. But it always shows the state as sealed.

Please help me to know the right way of unsealing the Battery Guage.

Thanks,

TXB0104: For appliying pull up register in TXB0104

Part Number:TXB0104

Hi team,

TXB0104 supports push pull output, but I'm wondering if this device can support I2C interface which requires external pull up. 

In datasheet, "If pull up or pull down resistors are needed, the resistor value must be over 50kohm."

So, when using over 50kohm pullup for I2C on some ch, can you tell if it's okay?

Thanks,

Best Regards,

TINA/Spice: variable duty cycle square wave generator needed

Tool/software:TINA-TI or Spice Models

Hi,

I need to replace an old rheostat from the 1930s that is no longer made.  It contains asbestos, so it can't be shipped and repaired. 

I was thinking that if I could build a variable duty cycle square wave generator, it would have the same effect as the rheostat.  I'd then run that output through an Op-Amp and to an SCR, and it would control the 250 V dc 300 Amp circuit. 

Does TI make a square wave generator with a frequency set by selection of a capacitor and the duty cycle set variable from 0% to 100% by a variable resistor?

Thanks.

Sincerely,

Del Ventruella

Part Number:CC3100

Hello!

I have some my own boards where CC3100 is used. In -20 degree C some CC3100 is working, some no. I can't understand why no(((((((((

The scheme is as in the datasheet of CC3100 (3,3V). The quartz is CX2520DB40000D0FLJCC, flash is W25Q80DVSNIG. 

What is wrong?

Thank You!
