Part Number:AM5728
Tool/software: Linux
Hi,
I am using AM571x EVM. Using processor SDK 05.01.00.11. I am using gst-launch1.0 to create gstreamer links to capture and display. I am able to capture 720p video using gstreamer using following command:
gst-launch-1.0 -v v4l2src device=/dev/video1 num-buffers=1000 io-mode=4 ! 'video/x-raw, format=(string)NV12, width=(int)1280, height=(int)720' ! vpe num-input-buffers=8 ! queue ! kmssink
I am trying to capture 1080p video.
gst-launch-1.0 -v v4l2src device=/dev/video1 num-buffers=1000 io-mode=4 ! 'video/x-raw, format=(string)NV12, width=(int)1920, height=(int)1080' ! vpe num-input-buffers=8 ! queue ! kmssink
But I am getting following error:
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Internal data stream error.
Additional debug info:

Should I configure v4l2 to capture 1080p. If required, what are the commands to configure it.
I tried changing the buffers in the above command but no use.
I tired to configure the v4l2 device using following command:
v4l2-ctl -d /dev/video1 --set-fmt-video=width=1920,height=1080,pixelformat='NV12'
I verified the camera and display using following command:
dmabuftest -s 35:1920x1080 -c 1920x1080@NV12 -d /dev/video1
Using above command I am able to capture and display 1080p video. How to do same thing using Gstreamer
Thanks and Regards,

Part Number:USB-TO-GPIO
Hi TI, can you please tell me how to run BQ Wizard 3.1.0. in Windows 10.
I have purchased the USB-TO-GPIO interface adapter, eval board (1901883/ BULK 915135) and worked fine on W7 machine but now i can see that is not compatible with W10.
My questions are:
- How can i run it and test the batteries on Windows 10?
- Will it be any newer version of this software. This one is since 2011.
Thank you very much.
Part Number:BQ25703A
Hello,
On page 12 of the datasheet, on the OTG CURRENT REGULATION section, the term regulation is used.
On the evaluation board, we have set the register REG0x09/08 to 1.6A.
When the current reaches this value, the OTG voltage cuts off.
Before cutting off, we have checked that the OTG voltage was higher then the VBUS UNDER VOLTAGE COMPARATOR threshold (85% of REG0x07/06().
Why the OTG voltage cuts off before crossing the 85% UV threshold?
It seems that the OTS CURRENT REGULATION acts like a current protection , not like a regulation. Do you confirm this observation? Or, is there some else we haven’t undersdood?
Regards,
AM

Part Number:TMS570LS3137
In AUTOSAR_MCAL_TMS570LSx-05.30.00 in the module Spi_Dlc.c on line 859 (function Spi_DlcError()) there is a potential out-of-bound array access, which generates a data access trap:
It seems the Error_u32 value of 180hex (384dec, please see Spi_Debug_1.png) leads to an out-of-bounds data access of the *.Spi_RxBank and this generates the data access trap (please see Spi_Debug_2.png).
In the end the OS reports the trap via Os_TrapHookReturn.
Part Number:DRV3245Q-Q1
I am looking for the full datasheet of the DRV3245-Q1 component. Could you share it?

In AUTOSAR_MCAL_TMS570LSx-05.30.00, the generated extern declarations from Spi_PBcfg.c are as follows
extern CDD_PM_TPS_Callback();
extern CDD_LSD_TLE_Callback();
extern CDD_IO_MCP_Callback();
extern CDD_IO_TIC_Callback();
extern CDD_PLCModem_Callback();

(missing return type and empty argument list (“variadic”))
And here is the compiler warning for the five callback declarations at the top:
"GenData/src/Spi_PBcfg.c", line 1234: warning: a value of type "int (*)()" cannot be used to initialize an entity of type "void (*)(void)"
The warnings have to be fixed.
Part Number:DRA71
Hello.
I am trying to calculate the power consumption for SoC DRA710 for one of our projects.
I have seen two reference designs for the processors power supply.
Implementation1: http://www.ti.com/lit/ug/snvu577a/snvu577a.pdfhttp://www.ti.com/lit/ug/spruif1a/spruif1a.pdf
Implementation2: http://www.ti.com/lit/ug/spruii3/spruii3.pdf
I am interested only in the 2nd stage power supplies because 3.3V and 5V voltages will be supplied from another ECU. Are there any pros/cons for either implementations?
Also, I am trying to calculate the S0C power consumption. In the datasheet it is only mentioned to contact you TI representative. Could you assist me?
Thanks
Part Number:TMS570LS3137
In AUTOSAR_MCAL_TMS570LSx-05.30.00, multiplexing of SPI4SOMI does not work
PortPinSpi4_4 is configured with PORT_PIN_MODE_SPI and PIN_V6_31 is configured with PORT_PIN_MUX_ALT_1. After initialization is complete, I can see that both control register bits PINMMR5[17] and PINMMR23[24] are set. According to section 4.3.2 of the user manual, this combination selects the "dedicated pad" instead of the "multiplexed pin" as input. From research I come to the understanding that SPI4 signals are only available on multiplexed terminals for package option 144QFP. As a result, SPI4 does not receive any data on its SIMO line.
What is the correct PORT configuration for correct SPI4SOMI initialization?
Part Number:TPS61086
Hi team,

In AUTOSAR_MCAL_TMS570LSx-05.30.00, The “Channels to Job” assignments are always generated in a fixed order, regardless of the configured order in the DaVinci Configurator Project. Currently, this only affects SPI communication with the Flash IC because this is the only external device for which multiple SpiChannels are assigned to one SpiJob.
The Generated code should follow the order of the configuration.
Required order of the channels in the Job:
static CONST(Spi_ChannelType, SPI_PBCFG) SpiChannelsToJob14_Assignment_at[] =
{
/* Number of Channels in Job */
2U,
/* Channels in Job */
Spi_SpiChannel_FLS_Data,
Spi_SpiChannel_FLS_Header
};
Generated Order:
static CONST(Spi_ChannelType, SPI_PBCFG) SpiChannelsToJob14_Assignment_at[] =
{
/* Number of Channels in Job */
2U,
/* Channels in Job */
Spi_SpiChannel_FLS_Header,
Spi_SpiChannel_FLS_Data
};

In AUTOSAR_MCAL_TMS570LSx-05.30.00, When the SpiEnableCs option is disabled in the configuration, it's also not reflected in the generated files. I have to manually place "SPI_NO_CHIP_SELECT" instead of the generated "SPI_SCSx" in the Spi_PBcfg.c
Part Number:TMS570LS3137
In AUTOSAR_MCAL_TMS570LSx-05.30.00, the Range for McuClockReferencePointFrequency is [5000000; 20000000]Hz. We need to use the Frequency referency for values beyond this range of 5MHz - 20MHz. The AUTOSAR specification ( AUTOSAR_SWS_MCUDriver.pdf - Parameter McuClockReferencePoint) does not provide such a limitation and the Range is [0 .. INF].
Can this range be extended atleast till 100MHz?
UseCase:
This McuClockReferencePoint is used to specify the LIN Clock reference which is VCLK and the value will be in the order of 80MHz for this project.
Part Number:TMS570LS3137
In AUTOSAR_MCAL_TMS570LSx-05.30.00,
We are facing issue with SPI Handler/Driver chip select while interfacing external flash driver. Below are the details.
Please check and provide your comments.
Attached is the open point issue list for your reference.
For communication with the external Flash Chip, several SpiChannels need to be transmitted sequentially. The Chip Select must be pulled LOW throughout the entire sequence. Therefore, the CsMode has been configured to CONTINOUS [sic!].
However, when measuring the SPI bus, we can see that the Chip Select Line is released for a short period of time during the transmission:
At first we thought that the Chip Select is released in between the transmitted channels. But actually that’s not the case. In the picture above, the first channel transmits one byte (0x9F) and the second channel transmits four bytes (0xFF). In short, the Chip Select toggle is seen before the last transmitted byte. We tried different scenarios and this seems to be the case always.
From our point of view, the SPI Handler/Driver violates AUTOSAR requirements. According to the Release Notes, the AUTOSAR_MCAL_TMS570LSx-05.30.00 supports AUTOSAR specification version 4.0.3. Within the “Requirements on SPI Handler/Driver” for this AUTOSAR Release, we found the following requirement:
[BSW12033] Chip select mode – hold mode
For an SPI channel assigned to an SPI HW Unit the chip select mode “hold” shall be available:
Selection of the assigned chip select pin before the transfer starts. If the transfer has been finished, the chip select is kept active. The SPI HW is kept allocated.
This seems not to be fulfilled by the driver properly and this deviation from AUTOSAR is also not stated in the Release Notes.
We considered using CS_VIA_GPIO instead of CS_VIA_PERIPHERAL_ENGINE to check if it makes a difference. But according to Texas Instruments, the MCAL does not support CS_VIA_GPIO at all (please refer to Open Point #1 in OPL_TI).
The “Specification of SPI Handler/Driver” states:
[SPI370] ⌈It shall be possible to define if the Chip Select handling is managed autonomously by the HW peripheral, without explicit chip select control by the driver, or the SPI driver shall drive the chip select lines explicitly as DIO […].⌋()
Part Number:TPS23754
Dear Team,
My customer wants to use TPS23754 for two RJ45 port for the redundant application.
Here is some question from the customer:
1. If both of the RJ45 port supply power will cause a short circuit or handshaking issue?
What is the issue need to be careful with two RJ45 port?
2. Can we setup priority for two RJ45 port?
3. If one of the RJ45 remove, can another port suppourt directly?
Both Ethernet ports must support 802.3at PD with automatic failover with zero downtime.

Hi,
I was wondering if you could tell me which clock source sould i mark and with which frequency as well as which is the recommended frequency to set to the SDRAM and EMAC(I don't know even what EMAC Stands for) on the PLL0 and why?
Thanks in advace,
Juan
