Part Number: TPS51200
Hi Team,
How to calculate the Vo voltage of the TPS51200?
Figure 30. in page 27, the R1 and R2 value is correct? If the R1 and R2 value are correct, how to calculate the VO voltage?

DP83822IF: Pull-down at XI in case of using Oscillator
Part Number: DP83822IF
Hi all
Would you mind if we ask DP83822IF?
There is the description "The DP83822 requires Clock to be present at PoR. In case clock is delayed, pull-down on XI is recommended to avoid spurious signal latch-up." on the datasheet P94.
How much does the value of pull-down recommend for it?
Does it depend on clock delay(trace lenght)?
Kind regards,
Hirotaka Matsumoto

CCS/PROCESSOR-SDK-TDAX: Code Composer Studio™ forum
Part Number: PROCESSOR-SDK-TDAX
Tool/software: Code Composer Studio
Hello everyone
I'm very new to code composer studio .
To get started saw some videos, it was mentioned I have to select device /boards for debugging.
I'm working with TDA4 development board, while TDA4 device selection option is not there .(code composer studio -9.2)
I tired with TDA3x but got error as shown below
Can anyone show me the right path to start over.
Thanks and Regard,
Akshatha.

TRS3243E: Two device using the TPS3243 as Automatic Power Down can't communicate each other.
Part Number: TRS3243E
I'm sorry my poor English.
・own product = OP ※OP use TPS3243
・OP(TPS3243 as Automatic Power Down enable) : FORCEON = L / FORCEOFF = H
・OP(TPS3243 as Automatic Power Down Disable) : FORCEON = H / FORCEOFF = H
※FORCEON = 23, FORCEOFF = 22
＜OK＞
・OP(TPS3243 as Automatic Power Down enable) - <RS232C> - PC
・OP(TPS3243 as Automatic Power Down disable) - <RS232C> - OP(TPS3243 as Automatic Power Down enable)
＜NG＞
・OP(TPS3243 as Automatic Power Down enable) - <RS232C> - OP(TPS3243 as Automatic Power Down enable)
If two device using the TPS3243 as Automatic Power Down can't communicate each other, what should I do?
Best Regard

TMS320F28388D: VSSOSC, ERRORSTS and VDD pin issue in F28388
Part Number: TMS320F28388D
Dear all,
I am design the HW of F28388, I found some mismatch between controlCARD and datasheet:
1. The ERRORSTS pin. The datasheet said this signal requires an external pulldown, but the controlCARD SCH shows the pin is left unconnected. I see in F2837x datasheet the ERRORSTS have internal pulldown, so no such external pulldown is required, is there any change for F2838x?
2. The VSSOSC pin. Datasheet said when using an external crystal do not connect this pin to the board ground, instead, connect it to the ground reference of the external crystal oscillator circuit. I see F2837x ref design do as this requirement, but in F28388 controlCARD, the VSSOSC connect direct to GND. Do we need to connect the VSSOSC and crystal ground together to the board GND?
3. VDD pin. Datasheet said a single 56Ω resistor (10% tolerance) should be placed between between VDD and VSS, this resistor provides a load to consume an internal VDD3VFL to VDD current source and avoid VDD voltage rising during low power device condition. But in controlCARD, we cannot see this resistor. Do we need this resistor?
Thanks.

CCS/TMS320C6457: Cannot load programs into DSP through HPI interface with Big Endian setting but works with little endian.
Part Number: TMS320C6457
Tool/software: Code Composer Studio
Hi everyone,
Our team is trying to load and run a program on DSP through the HPI interface with the ARM core of a Zynq FPGA.
We have made it done when we set both CCS project and DSP hardware(pull up the pin GPIO[0] A5) to little endian.
But when we switch all the settings to big endian, it doesn 't work at all.
The test programs, both big and little endian, are the same HelloWorld program. And they all work well if we load and run them through the emulator.
Because lots of our low level codes are written for big endian target, we need to solve this problem.
Could anyone help us to sort it out?
Thanks in advance!
PS: We are located in Guangzhou, China and if a FAE can give advice in person would be best.

Hi TI experts,
At present, it is found that the value detected by ADC is about 0.1 V higher when reading the power. It will take about 20-30 minutes before the value detected by ADC is the same as the actual value.
why？

打ち上げXL-CC2640R2:Not advertised with simple_peripheral_cc2640r2lp_oad_onchip
Part Number: LAUNCHXL-CC2640R2
simple_peripheral_cc2640r2lp_oad_onchip is not advertised and is not detected.
The procedure that was performed is as follows.
①Build the following projects in order
bim_oad_onchip_cc2640r2lp_app,persistent_app_cc2640r2lpsimple_peripheral_cc2640r2lp_oad_onchip_stacksimple_peripheral_cc2640r2lp_oad_onchip_app
②Merge each hex file
・The hex files generated by the build were merged in the following order.
mergehex was used for merging(infocenter.nordicsemi.com/index.jsp)
1. bim_oad_onchip_cc2640r2lp_app.hex
2. persistent_app_cc2640r2lp_FlashOnly.hex
1. and 2. merge→temp1.hex out
3. simple_peripheral_cc2640r2lp_oad_onchip_stack_FlashROM.hex
temp1.hex and 3. merge→temp2.hex out
4. simple_peripheral_cc2640r2lp_oad_onchip_app_FlashROM.hex
temp2.hex and 4. merge→order_merge.hex out
③write order_merge.hex using smart flash programmer2
④Scan with Btool and confirm
The corresponding sensor was not displayed on the Slave BDA.
In addition, we confirmed the display contents with Terra Term.
But nothing was displayed.
Am I doing something wrong?
Isn't the necessary setting done again?
Thank you.
The hex files generated by the build were merged in the following order.

AM3352: DDR3 / DDR3L EMIF tools
Part Number: AM3352
Hi Champs:
According this PDF, the Step3 Board Details is user to fit in.
And if we download this Excel tool from here: http://processors.wiki.ti.com/index.php/AM335x_DDR_PHY_register_configuration_for_DDR3_using_Software_Leveling
The "Board Detail Sheet" Green Places are locked.
If those Green filed are locked, how to let us fit in?
Then, the Green field of "EMIF Tool" Sheet are also locked.
But t,e "Register" Field are not locked.
I'm confused.
Those 3 Sheets are related, so, how is the sequences to fill those 3 sheets?

In the LCL filter, the calculation result of the calculation factor r of the inductance Lgrid and the inductance Linv is wrong.As shown below.
According to the calculation formula (6) of r, the calculated result is 56% instead of 2.7%, and the calculated value of Lgrid is also wrong. Therefore, if the calculation formula of r is correct, please give a correct answer.

Respected sir,
Based on Processor sdk 06_01_00_08 I am installed pdk packages and build the files using gmake then sd card images created for am5728 board.
I am loading to into AM5728evm based custom board but not displaying any data in serial port?
below procedure used.
- cd <PDK>/packages/ti/board/diag
- make <BOARD>_sd
- copy all the content under <PDK>/packages/ti/board/bin/<BOARD>/sd to your SD card
- copy the MLO to your SD card (default location at <PDK>/packages/ti/boot/sbl/binary/<BOARD>/mmcsd
- insert your SD card into your board and power on your board
- cd <PDK>/packages/ti/board/diag
- make <BOARD>_sd
- copy all the content under <PDK>/packages/ti/board/bin/<BOARD>/sd to your SD card
- copy the MLO to your SD card (default location at <PDK>/packages/ti/boot/sbl/binary/<BOARD>/mmcsd
- insert your SD card into your board and power on your board
- open Terminal emulator program eg: Teraterm to connect to the board’s UART console
Not displaying any data in serial port.
In this board I am not used EEPROM(U8) may be problem occurring for this or any thing problem.
How to solve this issue please give me some solution

LM27761: Effect on TLV4170 op-amp
Part Number: LM27761
Hi,
We are planning to supply the op-amp TLV4170 negative supply with the LM27761 to generate at -5V.
As we are using the Op-amp for ADC channels which are very sensitive to noise, will the LM27761 circuit cause any issue due to its high frequency (2 MHz) operation?
One of the main concern is the PSRR of TLV4170. We don't want to change the TLV4170 for this design.
Please suggest.
