Norton find "suspicious.cloud.9.f in the latest TI emulator update

August 3, 2016, 9:38 pm

I updated the TI emulator on notification of an update in CCS 6.1.3 but when I tried to use the debugger, it blocked the "tpi_icepick.dll" as having been infected with suspicious.cloud.9.f virus. I reported this to Norton as a false positive, but when I set up to exclude the file, I got another emulator dll file coming up as infected. This makes me think that the update files may be actually infected. 

My post is here mainly because there is NO way to directly report a 'bug' in CCS updates. At least, none that I can find.

   I would like to know whether DP83867IR/CR support inband status reporting of (link status, speed ..) in RGMII mode.

   If this part does not support inband status reporting, is there any other TI 1GE PHY which can opreate RGMII interface with 1.8V IO voltage supporting inband status reporting.

[CC1310] SBL for other platforms than x86?

There is an application report about CC2538/CC26xx/CC13xx Serial Bootloader Interface (swra466a).

Also, there is example project S/W of SBL (Serial Bootloader Library) for x86 PC platform.

So, can we get the sample project for other platforms than x86 PC?

The SBL is library only for PC platform.

Is it possible to get the SBL library for other platforms too?

 

Or, is there any example application of doing CC1310 (CC13xx or CC26xx) device firmware update using UART, SPI like common interfaces?

 

 

Regards,

Hayden

Connecting multiple cc2564 devices

Hi,

Currently we have a custom board design based out of CC2564 which combines A2DP + SPP for controlling external devices through android app. Things work pretty fine with single device and know we want to march towards adding multiple device support. In this regard, i am doing some basic home work, in parallel wanted community guidance to understand this better.  I have few basic questions based on my reading/understanding as follows:

1. As i read, Bluetooth spec says we can connect upto 7 device. Is this right? If so, does this mean we can control all 7 devices at the same.

2. For achieving #1, do we need any FW changes or code changes? 

3. I also came across BLE mesh. Is this something i need to explore? Does this require additional HW or FW support?

4. I heard from other folks that A2DP can't support more than 1 device. Is this true? 

4. Are there publicly available documents on understanding this whole concept? 

Sorry if these questions are very basic but i am have been talking to multiple folks and getting different views.  Please help me on understanding my basics if they are not correct.

AM3358 Starter Kit SPI Booting using starterware2.00.01

Dear All,

                 I am trying to boot my AM3358 Starter kit using SPI (winbond W25Q64FV) Flash. Till now I have successfully configured SPI with the kit and could easily write in SPI flash using Flash writing code provided with starterware. The problem is I am unable to boot it using SPI as the code for generating "boot_ti.bin" for AM335x starterkit is not available in starterware. Yes I do find a code for booting using SPI in am335x folder but it is very much specific for AM335x GP EVM module and is not working on SK(Starter kit) so I just stuck in the middle. Is it possible to boot directly from SPI without using Altera CPLD(installed on EVM module). If yes can anyone please guide me how to make correct "boot_ti.bin" file.

Note: My boot sequence is MMC0,SPI0,UART0,USB0

Best Regards

Ahmed

bq24192I - About the reset method of the register

August 3, 2016, 10:37 pm

Hello,
I have a question about bq24192I.

When the power supply of a terminal falls under the constant condition, register "REG00_Bit7" of the device comes to remain Enable.
I can not charge it without accepting an interrupt of the charge until a terminal starts.
There is the limitation that cannot communicate I2C until OS start.

I let the device be off once by removing a battery once and know that register values return to initial values.
If there is other methods to reset register, please teach me.

Regards,
Dice-K

Hi Team,

May I know if battery detection function is inside bq24780s?

This is captured at inductor output side without battery installed. Is this a kind of signal for battery detection ?

E-mail alerts on CCS release ?

Hello,

Is it possible for us to have an alert on CCS revise ?

My customer asked this. Their PCs doesn't have internet connection, therefore the CCS automatic "Look for update" doesn't work. They would rely on e-mail alerts.

CCS uniflash is good. It has   Alert Me  button. Honestly, we expect the same button for the CCS.

AM571x EMIF: T_RTW in EMIF_SDRAM_TIMING_1

Hello,

I want to use AM571x with DDR3-1600 memory as 532MHz. What value should I set T_RTW in EMIF_SDRAM_TIMING_1 Register? The parameter value is not listed on DDR3 memory datasheet. Instead, the calculating formula is described in it as below.
RL + tCCD - WL + 2tCK

e.g.) RL=11, tCCD=4tCK, WL=6
11+4-6+2=11
11 minus 1 is not able to set in the field of T_RTW (3-bit width).

I also don't understand how to be calculated the value by EMIF Tool (Excel). Please give me advice.

Regards,
Kazu

Hi TI,

Can someone explain how does this function HalUartISR being called:

#define HalUartISR                         interrupt_uart1

I only see function definition of HalUartISR in _hal_uart_isr. And tracing interrupt_uart1 it's in startup_ewarm.c and .map file of the genericapp.

I'm using cc2538 by the way

Best way to read data from UART

Hi TI,

I would like to receive 69 bytes from UART RX pin of my microcontroller. My question is, what's the best way to do it?

This is what I have in mind:

1.) Set the rx fifo level interrupt every UART_FIFO_RX1_8
2.) Read the RX 1/8 of the fifo inside the ISR callback function and save it to global buffer
3.) Set a global flag counter everytime step 2(above) happens
4.) Post a msg event inside the ISR if the global flag counter meets the predefined value = 69
5.) Process the uint8 buffer[69] in the msg event switch case

I'm quite confused on what is the best RX FIFO buffer len to be set during UART Initialization. I've looked into some references and I found out it should be power of 2.

New MSP-EXP430G2, registers as COM39 but can't be found for a debug session!

I just purchased a new MSP-EXP430G2 Launchpad, plugged it into my PC with USB and tried to deploy a 'hello world' application, but Code Composer isn't recognizing my board! I have browsed, researched, explored and tried a large set of existing E2E debug resolution attempts on "fail to connect to COM/FET" topics and threads, and nothing has helped resolve... :(

Here is my current status -


Configuration

    Launchpad MSP-EXP430G2 is connected to PC via USB

CCS Error (when debug is pressed)

   

 

MSPFlasher Report

   

 

Project Configuration

    Note that the project is also attached as a zip

   

Question

    What's the issue here, why won't CCS connect to the Launchpad, deploy and debug code?

Useful Context

    I have a large swath of currently working Launchpads right now - CC3200 Launchpad, CC2650 Launchpad, 430F5529 Launchpad, Tiva TM4C Launchpad...

Any help is immensely appreciated! Such a dang bummer, eager to play this weekend too!! :)

Hi all, please help me understand how to connect VCOM in differential output driver configuration. I understand the VCOM function when OPA1632 is used as ADC front end, biasing... But should I leave it open, grounded or grounded through appropriate capacitor  in differential output driver configuration. I saw all of 3 option used but can't figure out the difference.

Thanks
