Linux/AM5749: How to input RAW data into TIDL pipeline

June 6, 2019, 10:16 pm

Part Number:AM5749

Tool/software: Linux

Hi,

How to input RAW data on the memory into TIDL pipeline?

At SSD demo example, input data can be configured from on-board camera and is not file.

And this can be select by configureing the TIDL-API parameter numFrames.

>int numFrames

>Number of frames of input data (can be 0 if data is not read from file)

However, I cannot understand how to tie camera output and TIDL pipeline.

Actually what I'd like know is, the way to put the RAW data from GPMC into TIDL pipeline.

Best regards,

HaTa.

RTOS/AM5746: Data abort questions

Part Number:AM5746

Tool/software: TI-RTOS

Hi,
My customers are using a custom board with AM5746.
When frequent GPMC access, the phenomenon that ARM core data aborts occurred.
We think that it's related to Eratta's i878, and I have the following questions.

Question 1:
If a hangup of Eratta i 878 occurs, will the ARM core abort the data?
They wonder if the phenomenon that is happening now matches the phenomenon of i878.
MMU_Control.pdf
DFSR register : 0x00000211

(Please visit the site to view this file)

Question 2:
There is a statement about 0x482AF400 as a workaround of Eratta i878.
However, the details of this register are not described in TRM.
What kind of register is it?
Please let me know if you have detailed information such as documents.

Question 3:
I got the ARM core register information from customers when the phenomenon occurred.
Is it related to the hangup phenomenon of Eratta i878?
There is also the possibility of causes other than i878, so please let me know if there are other factors.
(If you do not have enough information to identify the cause, please let me know.)

(Please visit the site to view this file)

Question 4:
There are many possible causes for the DFSR register to become 0x00000211.
What is the cause of the data abort that occurred this time?

Hi there,

I use CCS v9 and I want to try to build vps examples using AM572xevm.

I imported below three files to my new CCS project from below path. 

Loopback_priv.h

Loopback_main.c

Loopback_test.c

C:\ti\pdk_am57xx_1_0_14\packages\ti\drv\vps\example\loopback\src

But, It doesn't build well. So I imported "loopback.cfg" and I tried to change any project settings, but I couldn't build it.

Please teach me everything steps from the beginning to the ends to execute on evm board.

Best regards,

I have a simple question but I can't seem to find the answer in the documentation.

In SPI_v0_HWAttrs, what is the csNum variable exactly ? Is it 0 or 1 corresponding to SPISCS0 and SPISCS1 respectively ?

What if I want to control the chip select by software without the driver being involved ? I have more than 2 slaves on the bus and I connected them to other GPIO pins on the DSP.

If this information is shown in any of the documentation, can you point me to it ? I can't seem to find it.

Hello,

As per the suggestion given in my previous query of Qt5 installation, I install qt-everywhere-opensource-src-5.7.1 from qt and also a tool chain of arm-8.2-2018.08 for my custom board. I configure Qt5 with following configure command 

./configure -prefix /usr/local/Qt-5.7-new-arm -release -pkg-config -continue -no-openssl -nomake examples -nomake tools -no-opengl -skip virtualkeyboard -skip webengine -no-cups -no-xkb -no-sm -no-separate-debug-info -xplatform linux-arm-gnueabi-g++ -qreal float

and successfully make install the Qt5 that will generate Qt-5.7-new-arm at /usr/local. 

Then I create a Test project in Qt creator and run in my Linux PC within the creator. This Test project run successfully in Qt creator.

Then I clean the project and build using qmake through terminal and generate binary using make command,

But when I cross compile the Test binary file with arm-linux-gnueabi-strip Test(my binary) then it will show the following error 

"/opt/arm-8.2-2018.08/bin/arm-linux-gnueabi-strip: Syntax error: Unterminated quoted string"

I did the same process that works fine with Qt4, but with qt5 and new tool chain, I got this error. Also I get the Test binary and try to run into my custom board using ./Test, then it will give error 

./Test syntax error : unexpected "(" . 

Is there any issue related to installation of above things or I install some wrong qt compiler with incompatible tool chain ?

Hello.

I have some am335x-evm board. For work something software I need kernel modules, which are not included to current board software.

I see, that version of kernel is:

When I try to install myself prepared (with arago-project.org bitbake) kernel modules I have error:

root@am335x-evm:~# opkg install kernel-module-esp4_3.12.10-r21k+gitrAUTOINC+2325bb5680-arago5.11_am335x_evm.ipk

I see, that there is different kernels VERMAGIC string. Is there a way to prepare (with arago-project.org bitbake or some other way)

kernel modules with right VERMAGIC?

I have an older project that I am resurrecting for some work, and I need to get the C6657 PDK v1.1.2.6.  I believe this was included in the MCSDK v2.01.02.06 for the C6657.  I originally developed this on a Windows machine, so I only have the installer for Windows.  I tried copying the windows version of the PDK directory (which I saved) to Linux, but I get an error when trying to import it.

Operation details:
Cannot complete the install because some dependencies are not satisfiable
com.ti.biosmcsdk.pdk.C6657.p2.feature.group [1.1.2.6] cannot be installed in this environment because its filter is not applicable.

 

 Does anybody have a link to download this software package (linux variant).  

Thanks,

HI,

My customer is now in progress to pass the compliance test for USB on 66AK2G12ABYA100 and they have some questions:

1. What is the TID number for this device ?

2. It seems they have to fill in the following registration form to use their system as USB-HOST.

And they are asking if the terms they have already written in the form are correct or not, for example, "SILICON MARKETING NAME", or some other items. Can you comment ?

As for "SILICON REVISION", I believe that is,as its name suggests, the device silicon revision that they are currently using. Correct, right ?

As you see in the original question for K2G, my customer is also having the compliance test on AM3352BZCZA100. What is the USB TID for the device ? Well, I found the following thread;

Is this still valid answer for the question ? I.e., the TID for AM335x is "Texas Instruments, Inc. AM335n" (where 'n' is the actual version of AM335x used by the customer) ? Not clear for me. Could you suggest ?

I may not be using the correct words but I will do best to describe what I want to do. I want to use mmap() to configure and read/write GPIO. Reference: SPRUH739 page 1512.  I want to set the pin mode of GPMC_AD6////GPIO_06 to INPUT, PULLDOWN, Pulldown Enabled. I understand how to set the individual bits in the register. I know the offset for the pin is 818h (page 1456).

What is the base memory address for the 818h register?

Page 5004 shows GPIO_DATAIN register at offset 138h. What is the base memory address for the GPIO_DATAIN register?

What page number in the manual shows the base address(s)?

Thank you,
