Hi,

I am using CCS Version: 7.4.0.00015 on a Windows 10 PC to work on a customized project_zero application which was developed by my colleague for CC2640R2F . I installed the simplelink_cc2640r2_sdk_1_50_00_58 to work on the project.

When I build the project, I am getting an error like "Product 'com.ti.SIMPLELINK_ACADEMY_CC2640R2SDK' v1.14.2.04 is not currently installed and no compatible version is available. Please install this product or a compatible version.". Can anyone suggest me a solution for the issue?

Thanks,

Collector receives sensor data and enters the Main_assertHandler(MAIN_ASSERT_HWI_TIRTOS); function。

I modify the collector's memory size to allow the collector to run properly for a period of time.

Throughout the program, I did not use malloc. All are global variable definitions

Look at the map file, and there's enough memory

bq77915 IC failing with DSG pin shorted to VSS

≪ Previous: RTOS/CC1310: Cc1310 collector does not work

Part Number:bq77915

We've had a couple of incidents of our bq77915-based battery protection boards failing which we've been unable to explain. The circuit we are using is straight out of the datasheet. I've attached a PDF of the schematic (it is missing a resistor between TS and VTB which has since been added).

On the board that failed, the DSG pin of the IC was internally shorted to VSS. Apart from that the IC was still functional. Providing the IC wasn't trying to drive the DSG pin high it would still power up and operate the CHG pin correctly. When it tries to drive the DSG pin then it draws too much current and the voltage at VDD drops to almost zero (voltage gets dropped across R1 - the series resistor on the VDD pin).

The MOSFETs were tested and found to still be working. There was some damage to the current sense resistor (R14), but it is possible that this was damaged mechanically during the disassembly of the battery pack. The current sense resistor is 1/2W part (Susumu KRL1220E-M-R120-F-T5).

The pack is charged at 300mA maximum. Discharge currents are substantially less (less than 100mA). The cells are 4S NCR18500A. We're not sure exactly of what conditions the board failed under. As far as we can tell it was just during normal operation (no short circuits, overloads, etc). There is also secondary protection external to the pack which prevents the cells from being completely discharged or overcharged.

We've tried to try to reproduce the failure on the bench by testing a range of conditions including shorting the output, over-charging and under-discharging. We've tried testing with the real load, as well as dummy loads with exaggerated inductances. Still, the IC has held up.

Any thoughts on what could produce this type of failure?

Part Number:SN74AVC16T245

Dear,

For SN74AVC16T245, in the datasheet, there are below description:

"To ensure the high-impedance state of the outputs during power up or power down, the OE input pin must be tied to VCCA through a pullup resistor and must not be enabled until VCCA and VCCB are fully ramped and stable. The minimum value of the pullup resistor to VCCA is determined by the

current-sinking capability of the driver."

it mentions the min value is related to the current sinking capability fo the driver, so how to choose the right value for the resister value, could you please give an example?

Thanks.

hi, i am new to TI

we are trying to build a protocol gateway (MODBUS and OPC-UA are main) where we need to collect the variables (around 20 thousand of quantity in total from both Ethernet and RS-485 combined) from MODBUS and CAN, then process those variable using multiple mathematical operations then we need to send it into a OPC UA client. this is the main purpose. now on top of this base program i want a local Webserver and RTOS (any soft-RTOS) to run. display and analogue input are least of my requirements, i want a high performance processor than can work upto 4 to 70 degree Celsius without any issue. high power consumption is not a problem as long as thermal handling is simple.

basically the product will be a communication gateway with few Digital inputs and outputs to filed devices ( a Programable Logic Controller in base). any help in selecting the processor is much appreciated.

i was looking into this "am5k2e04" and it looks good enough for me, please let me know your thoughts. thanks

Hello,

I am debugging the AWR1243BOOST, I want to know how to computer the CRC,

in the datasheet AWR1xxx_Radar_Interface_Control, in 2.3.4 section，I see "The CRC is computed on all the bytes in the MSGHDR and MSGDATA. Note that SYNC is not
included in CRC calculation" , and I choose 16 bit x16 + x12 + x5 + 1 16-bit CRC-CCITT, I collected a complete set of data, as below,

12 34 43 21 02 81 00 16 10 00 00 00 00 01 ED 67 01 40 00 08 00 01 00 00 C1 05

the 12 34 43 21 is the SYNC, and the last two bytes(C1 05) is the CRC, I have verified the CRC is correct.

Except the SYNC(12 34 43 21), I should compute 02 81 00 16 10 00 00 00 00 01 ED 67 01 40 00 08 00 01 00 00, I use all of the 16-bit CRC-CCITT algorithm and all the way，but all the result is not equal to "C1 05"

I also use C:\ti\mmwave_dfp_01_02_00_01\ti\example\mmwavelink_example crc_compute.c and the result is "97 B2" and not equal to "C1 05",

can you provide me a C code or verilog code better to computer the CRC? thanks very much

Hi,

My customer is doing power interrupt test, but the output voltage latched-off for some reason. I think this issue is similar to what discussed on the other thread. The input voltage is 12V and the output voltage is 5V.

https://e2e.ti.com/support/power-management/f/196/p/451494/1625681?tisearch=e2e-sitesearch&keymatch=tps54625#1625681

In his test, it took 8ms after returning input voltage from the time when output voltage goes below 65%. He tried 8.2nF, 100nF, 470nF SS capacitors as suggested in the thread, but it didn't work for all cases. Could you please help me solve this issue?

Best regards,

Hi,

There is a bootloader and an APP program in my project , and their interrupt vectors address have been redefined with LINK.CMD file , such as

BOOTLOADER_VECTORS (X) : origin=0x00000000 length=0x00000020

APP_VECTORS (X) : origin=0x00010040 length=0x00000020

Now , if a data abort exception is triggered when APP FW is debug in CCS , Program always jump to 0x10 , which is the entry address of dataabort exception by default.

And my question is as the interrupt vector has been remapped by LINK CMD file, why program doesn't jump to 0x010050 the remapping entry address of data abort exception.

On the other hand, If I reset CPU in CCS debug mode when debugging APP FW , program will jump to 0x00 but not 0x0010040 , the APP entry address after reset.

Would you please tell me how to fix it?

Thanks in advance.
