MSP432P401R: Heating issue
Part Number:MSP432P401R
Hi there,
Three MSP432P401R Development kit (two red board, one black board) has been purchased. out of three boards two of them heating up instantly after plugging the USB cable. (particularly MSP432p401R Chip).
1. Is it a problem, I am using MSP-FETflash Emulation tool with MSP-FET-432ADPTR (Rev 1.0) to flash the code.
2. I have configured the P4.5 as ADC and connected to one of the sensor analog output. For a duration time, I get expected voltage on this configured ADC pin(P4.5).
After some time, it was observed that voltage is always hanging around 3.0V to 3.1V on P4.5 (with respect to ground pin), Even after removing the sensor analog output from P4.5.
3.Another port pin(P4.0) has been configured for sensor analog output and now I am getting expected voltage continuously. But the problem is P4.5 hanging around 3.0V to 3.1V and MSP432p401R chip heating up with in a fraction of time.
Same situation with another Black development kit, but here P4.0 and P6.1 hanging around 3.0V to 3.1V.
These two are recent purchased boards. I have two older Development kits also, with same heating issue.
I had planned to use these boards for "water monitoring system" and code is working even after heating up. But this heating issue may cause a problem after real time deployment.
Please help me to overcome this issue, so that i can use these boards for my project.
Thanks,
Ajit

LDC0851: Detect Capability
Part Number:LDC0851
Hi,
Can LDC0851 detect the thin metal wire with a 1.5mm ~ 2.5mm width as a detect capability ?
In addition, I would like to make the sensor and reference coil more smaller.
For instance, the outer diameter is 100mils ~ 200mils.
So, could you please give me your advice about that ?
Best regards,

TMS570LS3137: ARM Hercules (_TI_auto_init)
Part Number:TMS570LS3137
I am trying to understand the functionality of library files associated with __TI_auto_init (files present in rtssrc.zip). To start with, from auto_init.asm, control goes to icall32.asm (IND_CALL assembly routine) and after analyzing I found control always branches at an instruction BX r4 and never get into BNE ep_16 label. Can anyone help me to understand how I can access the instructions present under ep_16 label. What is the purpose of BNE ep_16 instructions? If anyone can suggest any design document from TI regarding these library files (in "\ti\ccsv5\tools\compiler\arm_5.0.4\lib\rtssrc.zip") it will be very helpful to me.
For your reference I am attaching the screenshot of CCS debugging window.
Thanks.

TDA3XEVM: Setting of the EDMA on VisionSDK3.00
Part Number:TDA3XEVM
I would like to use McSPI LLD driver in DMA Interrupt mode with Chains_main function in Vision SDK 3.00,
The EDMA setting differs between the example code of the McSPI LLD driver and the program of VisionSDK,
I called the McSPI LLD driver in DMA Interrupt mode, but the EDMA interrupt does not work and the driver does not work.
I want to run McSPI LLD driver in Vision SDK environment with DMA Interrupt mode, but how do I change the EDMA setting part?
In VisionSDK, EDMA is set with the following source code.
C:\PROCESSOR_SDK_VISION_03_00_00_00\vision_sdk\links_fw\src\rtos\utils_common\src\dma_cfg\utils_dma_edma3cc.c
In the example of McSPI LLD driver, EDMA is set with the following source code.

CC2564MODN: CC2564MODN: Pairing enquiries
Part Number:CC2564MODN
HI
My customer is working on the CC2564MODN(slave) with his NXP MCU based on the STM32 Stacks. There are some observation which we like to seek your opinion:
- After pairing done and having a power cycle(power off and on), the stack can only detect the master if the Bluetooth master is reset as well. Is there any way to have an auto pairing after a power cycle?
- Is it possible for the CC2564MODN to save the mac of two different masters and switch by firmware to connect to one of the master of choice?
- After active connection is done, if we want to do pairing with another master. Can the pairing be done straight via firmware to disconnect and pair?

AM3358: UART RTS flow control
Part Number:AM3358
Hi,
I'm currently using UART2 to transmit/receive data which works fine. Now for one specific application the RTS signal is needed too (which I found at U2/UART2_RTSN) but it seems I do not get it working in my bare metal application. What I have done so far:
- pin-muxing, set CONTROL_PADCONF_LCD_DATA9 (0x44E108C4) to IEN|OFF|MODE6 (0x1A)
- while UART config mode is enabled (REG_CONFIG_MODE_B = 0x00BF = set), configure UART2 for AutoRTS by setting AUTO_RTS_EN in register UART_EFR (set bit 0x00000040 in address 0x48024008)
So...did I miss something? Is there anything else which needs to be configured in order to use AutoRTS?
Thanks :-)

Linux/TMDSSK3358: Qt5 performance issues
Part Number:TMDSSK3358
Tool/software: Linux
hi
We are testing using the am335x starter kit.
I checked the sdcard included in the am335x starter kit box. The touch point works fine, but the coordinates are problematic.
We were also happy with the implementation in the QT program.
So I installed ti-processor-sdk 4.2.0.9 and tested the pre-built image by writing to sdcard.
However, the log output to the serial port was different.
The output on the LCD was also different.
The prebuilt image of ti-processor-sdk 4.2.0.9 seemed to use wayland + weston.
But the bigger problem is performance.
ti-processor-sdk 4.2.0.9 prebuilt image is more than 30% cpu usage when button is pressed in qt5 calculator application.
I also saw a rack in a qt5 application.
So I built tisdk with DISTRO_FEATURES_remove = "wayland".
I tested the built image.
However, only wayland + weston was removed, but cpu usage or rack was the same.
How do I set tisdk to make the same image as the sdcard image included in the am335x starter kit?
In addition, how should the touch points be offset?
The same problem occurs when calibrating is executed and applied.
Then, have a good time at work

RTOS/TDA2XX: analytics2 and null source decode issue
Hi all:
We are trying to run vip_single_cam_analytics2 usecase (from vision_sdk/apps/src/rtos/usecases) and source is from the null source decode.
We found display always freeze at about 3 min : xx sec.
But when system read end of video file and return to start, the display can rework, but it freeze at about 3 min : xx sec again(Loop this situation).
We change different video has the same status, so this is not video issue.
We modify chains_vipSingleCameraAnalytics2.txt => remove SFM and SOF flow then display does not freeze.
So this is CPU / EVE loading or memory leak issue???

RTOS/CC2650STK: Read MPU 9250 Accelerometer Data Using CC2650 stk
Part Number:CC2650STK
Tool/software:TI-RTOS
Hi,
I have a CC2650 with Debugger Devpack, and I use CCS Version 6.2. I am trying to use the mpu9250 (built-in accelerometer), with some files from the SensorTag example source code, where the accelerometer is used. I already managed to initialize the accelerometer (calling sensorMpu9250Init()). Am using polling metheod and am not creating any call back fot this sensor.
I use the function sensorMpu9250AccRead((uint16_t*) &accData); defined in sensor_mpu9250.c, where accData is a uint8_t array of 6 length (this code has been extracted from the SensorTag example). Then, I set three int16_t variables (one for each axis) to convert the data of each axis, using sensorMpu9250AccConvert(accel_x); function. This is the portion of code I use to read the accelerometer data:
SensorMpu9250_powerOn();
SensorMpu9250_init();
// SensorMpu9250_enable();
if(SensorMpu9250_test())
{
Zan_Uart_Write("sensor self test passed \n\r");
}
Zan_Uart_WriteVals("CHEK DATA IS", b);
System_snprintf(str,80,"Total:%u Count:%u\n\r", mean, count);
Zan_Uart_Write(str);
Zan_Uart_WriteFloatVals("CHEK float DATA IS", b);
//while(1)
{
SensorMpu9250_accRead((uint16_t*)&accData);
range = SensorMpu9250_accReadRange();
Zan_Uart_WriteVals("RANGE IS",range);
Zan_Uart_Write("after MPU DATAread \n\r");
accel_x = (((int16_t)accData[1]) << 8) | accData[0];
accel_y = (((int16_t)accData[3]) << 8) | accData[2];
accel_z = (((int16_t)accData[5]) << 8) | accData[4];
accelx = SensorMpu9250_accConvert(accel_x);
accely = SensorMpu9250_accConvert(accel_y);
accelz = SensorMpu9250_accConvert(accel_z);
Zan_Uart_WriteVals("ACC X DATA IS", accel_x);
Zan_Uart_WriteVals("ACC Y DATA IS", accel_y);
Zan_Uart_WriteVals("ACC Z DATA IS", accel_z);
}
i got values as f.while i changed the type specifier %f to %d i got values are 0 always.range is getting as 2. is there anything missing in the code i need simple example code to see the data
please any one can help me ? its littile bit urgent
