Part Number: AM3358
Tool/software: Linux
I am trying to find a VNC (or any kind of remote access option) for the AM335 Beaglebone Black. I looked through a lot of documentation and forums but did not find anything clear.
At the very least id like to access my QT application remotely, though access to the shell would be helpful too.
Part Number: DRA744
Tool/software: Linux
In our system, DRA744 (J6) processor is connected to a SPC560B64 micro-controller over two SPI buses (GPIO7) and also some GPIO4 pins. Linux version 4.14.40 runs on the A15 cores of J6 processor. The IPU (m4) in J6 handles the communication between J6 and SPC560B64 over SPIs and GPIO pins. The IPU sends/receives data to A15 Linux over shared memory and hardware mailbox in J6. A loadable kernel driver in Linux handles the communication in Linux between m4 and A15. As soon as I insert the LKM into kernel, kernel generates continuously a large number of unexpected IRQ trap at vector 00. Something similar to this thread happens:
A part of dmesg shows the issue:

Hi
AM4372 USB0 signals are directly connected to USB type B connector, and USB host device is
connected to this connector.
I am concerned about the state of the USB terminal when AM4372 is power off and USB Host device is power on
Is there no problem if voltage is applied to the USB terminal while AM4372 is in the power off state?
Do I need to do some handling?
Best regards,
HaTa.

Dear Champs,
My customer is revisiting on our TDA3 device for 3D SRV as they decided to use internal ISP of SoC, and 4ch camera will be attached to TDA3.
But, my customer is still worrying about the 3D performance and feasibility of TDA3 running on DSP, and wants to know 3D SRV features can be implemented with similar quality with GPU of TDA2E.
Could you please check if below target requirement can be implemented on TDA3 as well?
Is there any limitation in the 3D SRV on TDA3 compared with GPU based solution like TDA2E?
Target requirements are
- 4ch. 1MP camera(LVDS)
- 2MP display after merging 4ch input image
- transparent mode
- Auto SRV Calibration
Thanks and Best Regards,

I'm usinng 128MB of QSPI-Flash on an AM5718 custom board.
QSPI interface has data register space only 64MB.
Q1) Is it correct with the understanding that QSPI Flash access of 64 MB or more must use the configuration port of QSPI?
Q2) Is there information on whether access using configuration port is supported by u-boot or linux qspi driver of ti-processor-sdk-linux?
Best Regards

Hi Biser
I am also confused by this question,my board with the same NAND (S34ML04G2) as mentioned above.\
My SYSBOOT9 = 0 selecting the ECC done by ROM，what wrong with this choice？Is that space area of ROM is not enough for ECC？
Hope for your help.

Hi
I want to use just I2S 2 and SPI in PPMODE.
But there is no option for that.
I want to use other ports as GPIO
Could you give me some solution?
Actually I want to use I2S2, SPI and GPIO 28, 29, 30, 31 port.
Please give me answer.

Hiii
We are using AM5718 custom board.Our requirement is to get 625i and 525i format output at the HDMI . But after following few threads we came to know that "Interlace feature has DSS IP level limitation for LCD but for HDMI, it’s driver level limitation." So is there any patch available to get this output ?? What are the changes required ?
Linux used : linux-4.14.67+gitAUTOINC+d315a9bb00-gd315a9bb00

Hello,
I am using IDK AM437x Board as profinet slave.
In the shared portal, I can use an unchanged stack to establish communication via Ethernet between the PLC and the Sitara board as a slave.
If I then adds another task to the test, then the communication is no longer. This means that the slave is no longer recognized.
I am using the following stack:

Please help.

Hello!
Can I please get an advice about CSI2 context interrupts in DM385?
MIPI CSI2 receiver in ISS system of DM385 can produce group of interrupts, called "context" interrupts and
controlled in CSI2_CTX_IRQENABLE_i registers. There are Frame Start and Frame End interrupts among them,
which in my understanding correspond to reception of MIPI frame start and frame end short packets.
Do these interrupts have obligatory follow each other? That is, can two frame starts be produced in a row,
without frame end?
At least in debug mode it looks like they have to alternate . Attempt to write to CSI2_DBG_H register two start packets one after another,
(with some interval between writes)
produces only one interrupt, But if frame end inserted between them, all three interrupts can be observed.

Hello,
I would like you to confirm about below.
*
Q1. According to product page, There is following figure about LCD EVM
Touch Panel is covered by clear board. However, my customer receiverd following board in fact.
Touch Panel is covered by black board and can see logo of "Texas instruments".
Could you please confirm whether this LCD board is expected one ? (If so, is information of product page old ?)
Q2.
My customer said when he receiverd LCD EVM, PHD has already opened as shown below(highlighted red).
Is that also expected condition ?
(After closing PHD, do you perform any test before shipping to customer ?)

Hi All,
Does TI has a CVBS to MIPI CSI2 video decoder which gives progressive data output?
We need to connect the decoder to capture data from CVBS cameras and feed that data to ISS Capture of TDA2P
