Hi,
Could you let me know the maximum returning time from Sleep mode, please?
Datasheet of page 12 shows that Typ value is 1ms.
We want to know max time.

Linux/DRA725: Support NV21 format input in DSS
Part Number:DRA725
Tool/software: Linux
Hi Expert,
DRA7xx TRM say it supports NV21 format input, so far the Linux DRM/DSS driver can not input the format as NV21. Would you please suggest how to change the driver code to support that? If need reprogram the VIDx_FIR_COEF_H_i /DISPC_VIDx_FIR_COEF_HV_i, DISPC_VIDx_CONV_COEFx, any suggested value?
Best Regards.

TPS2378: In-Rush Current Issues.
Part Number:TPS2378
Dear Ti,
I have faced some issues on in-rush current from your TPS2378 and would like to clarify further with you on the below.
1. From the values of the datasheet for TPS2378, what are the major differences of the current limit and inrush current limit data? I assume that current limit is the current during the working condition and the inrush current is the input current drawn by the device during the initial turn on.
2. This inrush current limit is generated by the PD interface IC itself ? Or it means that the PD interface IC has an ability to handles the inrush current from external circuit?
3. What is the major cause of the in rush current keep increased?
4. If the inrush current limit is >180mA what will happen?
5. Is there any maximum period for this inrush current limit? For example the typical is 140mA and how about the withstand time?
6. Found that if the larger of Cbulk capacitance will prolong the inrush current time period, tried capacitor 100uF inrush current prolong period is around 50ms, 470uF is 250ms....Will the prolonged period cause any problem on the PD interface IC?

LAUNCHXL-CC1350: Setting data rate in SmartRF Studio 7 does not produce correct symbol rate on the air
Part Number:LAUNCHXL-CC1350
I am trying to configure a proprietary 16384 kbps OOK modulation using SmartRF Studio. When I record the signal on air, however, I see the wrong symbol rate. And worse, I see different symbol rates for the preamble, as I do the packet data. For the preamble, I see roughly 10951 kbps, and for the data, 14513 kbps!
Here is the config I'm using in SmartRF Studio:

TLV62568: TLV62568
Part Number:TLV62568
Hi
I am testing the maximum output range of TLV62568. As per the datasheet, it is 5.5V. I am setting the output to 5.5 using feedback resistors. The values selected are R1= 200K and R2=1.65Meg. Can I use this value or you have and preference for resistance value for low current consumption and noise sensitivity. Please let me know.

DRA756: Display Subsystem
Part Number:DRA756
Hi,
I have a query regarding display ports for Jacinto6 Plus.
According to TRM, there are 3 LCD outputs, providing support for MIPI DPI 2.0, or BT-656 or BT-1120.
Do these display ports support LVDS interface?
Can you give me a list of the interfaces supported by the display ports?
Thanks,

Linux/AM5728: I want to incrase size of continuous memory for vivante(gc320).
Part Number:AM5728
Tool/software: Linux
Hi. we need various continuous memory of vivante(gc320) for GUI. total size is 80MB.
- 1280x720, 1920x1080, 1280x300, and so on. total size is 80MB.
As we trace gc320 drvier, we often notice allocating non-continuous memory for short continuous-memory as below it.
#define gcdDEFAULT_CONTIGUOUS_SIZE (4 << 20) at extra-drivers\ti-gc320-driver-5.0.11.p7\hal\os\linux\kernel\gc_hal_kernel_probe.c
If we increase gcdDEFAULT_CONTIGUOUS_SIZE -> 16MB or 32MB, we find decoding error(VPE memory). How do increase it ?
As other solution, we can consider TI OMAP or CMEM.
but, we have short memory for limiting TI OMAP memory(128MB), and then we don't use TI OMAP memory(it already three display, 3D GPU and IVA-HD).
If we CMEM ( we use CMEM_alloc2 API( internaly it return mmapd address(at cmem-mod-4.14.00.00+gitAUTOINC+b514a99ac4\src\cmem\api\cmem.c ) ) , this API is used VPE for deinterlace , it works very good ), vivante gc320 have error as below it.
status = gcoSURF_SetWindow(lpSurface->Surface, 0, 0, width, height); -> gckKERNEL_Dispatch ( gc_hal_kernel.c ) -> case gcvHAL_MAP_USER_MEMORY -> gckOS_MapUserMemory have error.
In order words, vivante gc320 driver don't support importing cmem when i use CMEM_alloc2 API .
I want to allocate continuous memory but non-continus memory at vivante gc320 . How can i work it ?

TPS5402: Reverse voltage condition
Part Number:TPS5402
Hi,
We got a question from the customer about TPS5402.
Could you help us?
[Question]
- When the power supply is not applied to VIN, the output voltage conducts through the body diode and the less than 1mA current flows to VIN. Please refer to below figure. Are there any concerns on this condition?
- How much is the maximum recommended currnet of the internal body diode?

RTOS: VPE link for resizing input image
Tool/software:TI-RTOS
Hello,
I am using VPE link for resizing input image and output should of res. :640x480.
Usecase is,
Capture -> VPE -> Display
I have set below create time params for VPE,
vpePrm->enableOut[0] = TRUE;
chPrms = &vpePrm->chParams[0];
chPrms->outParams[0].numBufsPerCh = VPE_LINK_NUM_BUFS_PER_CH_DEFAULT;
chPrms->outParams[0].width = 640;//OutWidth;
chPrms->outParams[0].height = 480;//OutHeight;
chPrms->outParams[0].dataFormat = SYSTEM_DF_YUV422I_YUYV;
chPrms->scCfg.bypass = TRUE;
chPrms->scCfg.nonLinear = FALSE;
chPrms->scCfg.stripSize = 0;
//chPrms->scCropCfg.cropStartX = 0;
//chPrms->scCropCfg.cropStartY = 0;
//chPrms->scCropCfg.cropWidth = CAPTURE_SENSOR_WIDTH;
//chPrms->scCropCfg.cropHeight = CAPTURE_SENSOR_HEIGHT;
So,this get successful build and execute with no run time errors.
But output is cropped(not resized) with starting from 0,0 to 640, 480.
Need suggestion for,
is there missing any params to set?
why output is getting cropped?
