TMDSEVM3730: Connecting USB_OTG without using USB transceiver chip.
Part Number:TMDSEVM3730
Hi, Sirs,
I have some questions about technical issue of USB transceiver on the TMDSEVM3730 board.
On the board schematic, USB_OTG have two way connections to the PMIC and CPU
First way is USB_OTG data is going through using USB transceiver(Part No.=ISP1507BBS) to PMIC and CPU
Sencond way is USB_OTG data is going straight through connector(Part No=CON_PMC_30X2_M) to PMIC and CPU, but this way is disconnected in default
So what I did;
1. In the first way, I disconnected line of VBUS of USB transceiver(Part No.=ISP1507BBS) not to use part this USB transceiver any more.
2. In the sencond way, I put with all 0 ohm resistors(R214 ~ R225) on the connector(CON_PMC_30X2_M) to go from USB_OTG through P15 to PMIC and CPU.
However, these works don't make to USB_OTG works. For debugging, I only can see the HSUSB clock wave, but there are nothing on any datas on HSUSB_DATA0 ~DATA7.
What should I see more detail to use USB_OTG without using USB transceiver?

TPS53647: Layout question: Analog Ground?
Part Number:TPS53647
I need a little clarification as to whether it's necessary to have an analog ground for the TPS53647 controller with a single point ground vs simply connecting external component returns to the system ground plane.
The data sheet Layout instructions and the eval board appear to have an analog ground layer that is connected to the power ground at a single point through a 0 ohm resistor.
However, the layout for the 3-phase PMP10962 reference design has some controller components tied to a single point while others tie directly to the ground plane on the top layer. Device thermal pad appears to connect to ground plane on several layers including the top (controller mounted on bottom layer of PMP10962).

CCS/CC2640R2F: About the selection for simplelink_cc2640r2_sdk_1_40_00_45 at the "Resource Explorer" of CCSv7.4.0
Part Number:CC2640R2F
Tool/software: Code Composer Studio
Dear Sirs,
I have installed simplelink_cc2640r2_sdk_1_40_00_45 & simplelink_cc2640r2_sdk_1_50_00_58 at CCSv7.4.0. But I can not see simplelink_cc2640r2_sdk_1_40_00_45
appeared at the "Software " of CC2640R2 Lanuchpad" whenever opened "Resouce Explorer" to check the SDK. I only see the simplelink_cc2640r2_sdk_1_50_00_58 appeared
at "Software" of "CC2640R2 Lanuchpad" whenever opened "Resource Explorer". Since I need to exercise ble5stack examples but they only existed at simplelink_cc2640r2_sdk_1_40_00_45,
that is why I need to switch to this SDK and then I can run ble5stack examples as desired. Can any expert tell me how to resolve this issue ? Thanks a lot.
Best Regards,
Bolo

Hello,
I am a senior in university working with the TMDSLCDK138 to do some audio processing. I was wondering what the best way would be to implement a UART communication on the TMDSLCDK138 would be. I need the data sent over the UART to change the effects on the DSP processor while it is running.

UCD3138: is there a program design specification for UCD3138 digital power supply
Part Number:UCD3138
Hello.
I am learning the firmware code for your public UCD3138 full-bridge hard-switching power supply.
I was just getting started with the UCD3138 software design.
After I opened the firmware code, I found that there were many source files, header files, and some files that I did not understand.
I would like to ask, how can I learn the firmware code, is there a program design specification? For example, introduce each file type, program design flow, main program structure and so on.
Thank you.
If you can help, be grateful.

DS100MB203: can I use TI device into my application?
Part Number:DS100MB203
Hi,
We consider TI's DS100MB203 MUX for below structure, and wonder whether we don't need any additional retimer or repeater when using DS100MB203.
If yes, please recommend a better product among DS100MB203 and DS125MB203.
(at TI website, the only difference is Peripheral I/O and could you also explain about this function if possible?)
If no, please recommend a suitable TI repeater or retimer device can be used with DS100MB203.
thanks,

Hi all:
We are developing the WL1837 module, and some costomers asking whether the WL1837 chip support the BT4.2.
If supported ,what are the differences and how to design including the software and hardware or BT stack?
The costomers of us said that the NFore module (TaiWai companny,use WL1837) supported the BT4.2,
So expect to reply as soon as possible and give us more detail information about the WL1837 , thanks !!!

RTOS: RTOS/TDA2x get encoder buffer issues
Tool/software:TI-RTOS
I am facing issues in dump data to SD card when i run my usecase on TDA2x EVM.
My usecase like this,
Capture->dup->Enc->Dec->Merge->Display
Now I want to dump encoder data to SD card. So I use the System_getLinksFullBuffers to get the buffer between Enc&Dec Link after start the app.
the issues is:
1.I found the function sometimes can not get buffer data. It will return with numBuf = 0;
2.The SD write speed is to slow(5MBytes/s). How can i improve the speed.
3.I found the MJPEG data dump to SD is the same despite the data size is 1024*720 or 960*540.
4.If i dump h264 data to SD card. VLC can not play the video.
