Part Number: TPS55010
Dear TI team:
My customer used TPS55010 for 5V to 5V isolate application, they found TPS55010 heat up when there is no load, please help to check what is the problem? Thanks!
Is it because IC thermo pad is not connected to the ground PIN of 55010, and there is too little ground on the top layer?
Thanks!
Regards!

Part Number: LM3424
Dear All：
I received the question from my customer.
The LM3424 are implemented the high side current sense function.
Can this current sense use as low side current such as following ?
in my customer application, they must put the sample resistance on the low side, if the LM3424 can't meet the function , can i add extra circuit to implement the needs？
or can you suggest other IC to meet the application？ Thanks
Part Number: AM5728
Hello Champs,
Customer used the uart driver in ti-processor-sdk-rtos-am57xx-evm-04.03.00.05. The parameters are configured as below:
UART_init->open 2 uart: uart_handle1 = UART_open(0, &user_params);uart_handle3 = UART_open(2, &user_params);->use UART_read(uart_handle1, buf_r,20); and UART_write(uart_handle1,buf_r,20); to realize PC->dsp->PC data flow.
The test result is that except 0xFF data, other data could be sent correctly. When PC sends 0xFF to DSP, there is no data return.
Customer can catch the 0xFF from uart TX data line, it means the PC has sent 0xFF to DSP correctly. Then he tracked the UART receive register, it can catch the 0xFF correctly. 
Then he tracked the UART_gets(&x, 1); further, 
He found that uart can receive the 0xff, but it can't return when reading.
Is it a bug for the uart driver?
Thanks.

Hello:
I would like to consult you about the usage of TCA4311 chip. As shown IN the figure below, if I want to do hot plug and unplug, should my PSU PMbus connect IN or OUT of the chip?

Hi Team:
There are series DC/DC module application and RD study below condition at first.
Condition : Vin_dc= 36~72V , Vout= 3.3V , Iout= 15A
RD study LM5026 , EVM and would like to add OVP function that it could be reset , any suggestion ? or which controller is more better ?
Please help it , thanks.

Hello,
Could you pls inform the OVP accuracy of UCC28740? we don't find this spec on datasheet. thank you.
Part Number: LMK03033
I found a circuit problem recently, and the problem is that I feed a 10MHz refernce clock with 3 Vpp to LMK03033. The datasheef recommanded maximum value is 1.6Vpp. The function seems worked many years, but I sitll want to know if any side effect to this situation.

Hi Specialists,
Question about driver task (slHostStackThread), Sample code in SimpleLink SDK,
\examples\rtos\MSP_EXP432E401Y\demos\ethernet_wifi_tcp_echosl_host.c in SimpleLink_sdk_wifi_plugin folder,
We are trying to implement driver task based on "slHostStackThread()".
This function seems to generate sl_Task, connect to AP than acquired IP at DHCP then return finishing this task.
In case of IP can't be acquired DHCP lease, how do we process?
Thank you.

hi,
What is the output impedance of the chip(iwr6843)? The phase of chip pin seems inconsistency,what causes this phenomenon? The phase of erery antenna is the same.
Part Number: CC3120MOD
Hi Specialists,
We have Question about system shutdown, reboot and Wi-FI on/off
is it no problem just only let sl_Task terminated while Wi-Fi is ON? If there are any process need to be considered before task termination, please advise.
For rebooting procedure from Wi-Fi off to WiFi on, is it no problem that once generate slHostStackTread, resetting and then generate sl_Task again?
Can you kindly help solve this question?
Thank you.

Hi,
I wrote a customer alg_plugin reference framecopy. And I try to send parameters to my alg_plugin with System_linkControl and AlgorithmLink_AlgPluginControl.
My alg_plugin does receive the command. But it seems have no interface to get the parameters. So how do I get my parameters ?
The code send my command and parameters
case '1':
System_linkControl(
chainsObj.ucObj.Alg_stitchLinkID,
STITCH_SET_DATA,
stitchBuf,
sizeof(stitchBuf),
TRUE);
Vps_printf("chains buf0 0x%x,buf1 0x%x, buf2 0x%x\n",stitchBuf[0],stitchBuf[1],stitchBuf[2]);
break;The code receiver control
Int32 stitch_control(void *pObj, void *pPrm) {
AlgorithmLink_StitchObj * stitchObj;
AlgorithmLink_ControlParams * pAlgLinkControlPrm;
Int32 status = SYSTEM_LINK_STATUS_SOK;
stitchObj = (AlgorithmLink_StitchObj *)
AlgorithmLink_getAlgorithmParamsObj(pObj);
pAlgLinkControlPrm = (AlgorithmLink_ControlParams *)pPrm;
/*
* There can be other commands to alter the properties of the alg link
* or properties of the core algorithm.
* In this simple example, there is just a control command to print
* statistics and a default call to algorithm control.
*/
switch(pAlgLinkControlPrm->controlCmd)
{
case STITCH_SET_DATA:
Vps_printf("############alg stitich set data\n");
break;
default:
break;
}
return status;
}

Hi Specialists,
We have following questions from customer, can you kindly help provide the answers?
1.
For receiving API , sl_Select(), sl_RecvFroml, is it possible to call them without exclusive control?
2.
Regarding 2.4GHz channel, should we consider the upper layer application that the channel limitation which can not be used over 12 channel in US? In case yes, how it can be controlled. Please advise.
3.
Is there other reference sample code except SimpleLink SKD sample code in /example folder? If there is reference code for aquring SSID list or connection procedure, please advise.
4.
Regarding acquiring the version information , ChipId, FwVersion, NwpVersion, PhyVersion and RomVersion.
The version of FwVersion and PhyVersion has not changed between 1.60.00.07 and 2.40.00.22 of the SimpleLink SDK plug-in. Will there be a possibility that the version will change when the service pack is upgraded in the future?
What kind of the version information does ChipId and RomVersion indicate?
5.
We are currently replacing the applications developed with other protocol stacks with SimpleLink.
In original protocol stack, after creating socket and binding, a callback function is linked to the socket, and when a reception event occurs for the socket, the callback function is called from the protocol stack and then RecvFrom It is processing such as executing.
As long as you read SimpleLink's Programmer's Guide, it seems that such a mechanism (registering event callback function for socket) does not exist in SimpleLink, but is it correct? Do you have a sample like that?
6.
(About burning the service pack) I am trying to create a ROM image file (bin file) for writing service pack with UniFlash tool.
As wrote in swru467a CC3120 SDK Getting Started Guide Chapter 4 (Programming the CC3120 BoosterPack), I careated the writing image, but there is following 2 "Device Mode" settings in step 6.
・ Develop
・ Product
-What is the difference between these two settings?
- We should write the image set to "Product" when product shipping ?

Hi Team,
My customer set up the AOA environment as our document shows. With the original example in SDK 3.30,the angle was jumping and fluctuating a lot. After he modified to use only two antennas, the angle only showed 5.6.7 values no matter how he moved the slave board. Whether the BOOSTXL-AoA plugged or not, it always got the same value. Which looked like the antenna was not working.
SDK version: 3.30 [Also tested on 3.20, same result]
HW: TI board

Hello,
I am new to TI-RTOS before exploring i would like to know if we can use TI-RTOS for my CC3220MODASF to use it for IOT applications. does the TI-RTOS kernel has the stack required for connecting to internert , can i use API to connect it wifi and also if i need to use Azure cloud does it have any API for it .
thanks,

Hi,
WL8 tried to connected with AP router with 11n mode ONLY.
But got refuse error code 18 as below

This issue seems about data rate in assoc request packet. Any idea how to fix this issue???
Left is from WL8. Right is from AP router.

Hi Team,
Previously, customer wanted to connect the Bluetooth module on the board. Later, he used a three-meter to test the voltage because the module did not work. In the end, he found that the AWR1642 did not work, and the N_REST and 5V LEDS did not light up. Customer would like to know is there any way to resolve it?
Thanks.
Part Number: TPS60150
目前的設定為:
Flash on
TPS61050_Data_00 = 0x90;
TPS61050_Data_01 = 0x96;
TPS61050_Data_02 = 0x00;
TPS61050_Data_03 = 0xDF;
FLASH_SYNC = High
Flash off
TPS61050_Data_00 = 0x10;
TPS61050_Data_01 = 0x16;
TPS61050_Data_02 = 0x00;
TPS61050_Data_03 = 0xDF;
FLASH_SYNC = Low
目前狀況是正常的，想跟您確認設定是否正確?
另外先前的設定:
Flash on
TPS61050_Data_00 = 0x90;
TPS61050_Data_01 = 0x96;
TPS61050_Data_02 = 0x00;
TPS61050_Data_03 = 0x60;
FLASH_SYNC = High
Flash off
TPS61050_Data_00 = 0x10;
TPS61050_Data_01 = 0x16;
TPS61050_Data_02 = 0x00;
TPS61050_Data_03 = 0x60;
FLASH_SYNC = Low
狀況是很微亮，且再將TPS61050_Data_03 設成0xDF也無法更新狀態，除非完全斷電。
請問這個現象正常嗎? 還是設定上流程需修改能將TPS61050 setting reset ?
