Hi,
From the thread below, it is stated that DSPLink is not compatible with ProcessorSDK 05_03_00_07.
May I know what is the incompatibility?
Part Number: TMDSCSK8127
I work with TMDSCSK8127 board
Using DM8127 IPNC RDK Release (v3.9.1)
At TI81XX PSP PM SUSPEND RESUME User Guide I see the next:
To turn off power domains with power switches if they are idle(no clock is active) during suspend enable following
flag:
$echo 1 > /sys/kernel/debug/pm_debug/turnoff_idle_powerdomains
To disable this:
$echo 0 > /sys/kernel/debug/pm_debug/turnoff_idle_powerdomains
But my target filesystem doesnt have the /sys/kernel/debug/pm_debug folder
It s just has /sys/kernel/debug folder and this folder is empty.
How should I build filesystem to get the filesystem with /sys/kernel/debug/pm_debug folder?

Hi, All,
We connects TF card to the AM3358 MMC0 port.
During the TF card initialization, the CMD16 command always fails.
And using oscilloscope, we noticed that after the processor executes CMD4 command, the CMD signal line becomes distorted as you can see from the attached captured waveforms below.
What is the possible cause of this issue? should CMD4 be removed during card initialization?
Thanks,
1) the waveform of CMD4 command.
2) the CMD signal distortion after CMD4 command.

Hi forum,
I am getting super frustrated by not being able to run the OS Clock module run properly on the DSP1 of a AM5728.
I am trying to use GPTimer14 (Id:13) that is configured in the Linux Device Tree as belonging to DSP1.
Therefore I made a simple project that replicates the problem which contains the .cfg, a makefile and one .c file.
Basically, I launch a task that should sleep for 1000ms and print something every time sleep expires.
Additionally, I defined the Clock as USER type and I am calling Clock_tick() myself from a custom function but this is never called because the Clock tick is stuck at zero.
static int n = 0;
Void myTimerTick(UArg arg)
{
Clock_tick();
n++;
if(n%1000 == 0)
{
Log_print1(Diags_INFO, "Clock_tick() %d\n", n);
}
}
/*
* ======== main ========
*/
Int main(Int argc, Char* argv[])
{
Error_Block eb;
Task_Params taskParams;
Log_print0(Diags_ENTRY, "--> main:");
/* must initialize the error block before using it */
Error_init(&eb);
/* create main thread (interrupts not enabled in main on BIOS) */
Task_Params_init(&taskParams);
taskParams.instance->name = "task";
taskParams.arg0 = (UArg)argc;
taskParams.arg1 = (UArg)argv;
taskParams.stackSize = 0x1000;
Task_create(main_task, &taskParams, &eb);
if (Error_check(&eb)) {
System_abort("main: failed to create application startup thread");
}
/* start scheduler, this never returns */
BIOS_start();
/* should never get here */
Log_print0(Diags_EXIT, "<-- main:");
return (0);
}
/*
* ======== main_task ========
*/
Void main_task(UArg arg0, UArg arg1)
{
Log_print0(Diags_ENTRY, "--> main_task:");
while(1)
{
Task_sleep(1000);
Log_print0(Diags_INFO, "System_sleep() returned %d\n");
}
Log_print0(Diags_EXIT, "<-- main_task:");
}I should add that I confirm that my GPTimer14 is properly working (base: 0x4882A000, TCLR=0x3, TCRR-increments when debugger stepping).
Please provide some RTOS or DRA7xx expert advice on this as I couldn't find any solution myself.
Best regards

Hello TI,
I am using a general purpose EVM of AM5728. I am using ti-processor-sdk-linux-am57xx-evm-06.00.00.07 SDK.
I have a usb uvc webcam connected to it. I am trying to use the webcam through VIP VPE IVAHD MPEG4 ENCODE/DECODE app,
But I got the following error message and doesn't work.

Hi Champs,
We would like to confirm which is real L2 cache value on the each of C66 core pack.
According to this Figure 1-1 , each of C66 core pack L2 memory size is 1024KB.
On the other hand , this 1.8.4 L2 capacity mentioned maximum 256Kbyte.
So, we used to set this L2 size at CCS standard lib.
ti_sysbios_family_c66_Cache.initSize.l2Size = ti_sysbios_family_c66_Cache.L2Size_256K;
So, which is maximum L2 size number ?
If it is 1024K is available , can we set ti_sysbios_family_c66_Cache.initSize.l2Size = ti_sysbios_family_c66_Cache.L2Size_1024K; ?

Hello,
I am using existing vxlib for resizing a image.The location of the Vxlib is :
C:\PROCESSOR_SDK_VISION_03_03_00_00\ti_components\algorithms\vxlib_c66x_1_1_1_0\packages\ti\vxlib\src\vx\VXLIB_scaleImageBilinear_i8u_o8u.
The function is :VXLIB_scaleImageBilinear_i8u_o8u
My input image is 384×288，output is 768×576.
My codes are below:
unsigned short srcWidth = 384, dstWidth = 768;
unsigned short srcHeight = 288, dstHeight = 576;
float xs = (float)srcWidth /(float)dstWidth;
float ys = (float)srcHeight/(float)dstHeight;
unsigned short srcStride = 390, dstStride = 770;
unsigned int srcBufWidth = VXLIB_max(srcStride, ((dstWidth+2) * xs)+2);
unsigned int srcBufHeight = ((dstHeight+2) * ys) + 2;
unsigned int srcBufXstart = (srcBufWidth - srcWidth)/2;
unsigned int srcBufYstart = (srcBufHeight- srcHeight)/2;
VXLIB_bufParams2D_t src_addr, dst_addr;
float xScale, yScale;
int status_opt = 0;
src_addr.dim_x = srcBufWidth;
src_addr.dim_y = srcBufHeight;
src_addr.stride_y = srcBufWidth;
src_addr.data_type = VXLIB_UINT8;
dst_addr.dim_x = dstWidth;
dst_addr.dim_y = dstHeight;
dst_addr.stride_y = dstStride;
dst_addr.data_type = VXLIB_UINT8;
xScale = (float)srcWidth/(float)dstWidth;
yScale = (float)srcHeight/(float)dstHeight;
status_opt = VXLIB_scaleImageBilinear_i8u_o8u((Uint8 *)buffTemp, &src_addr, (Uint8 *)outputPtr, &dst_addr, xScale, yScale, -srcBufXstart, -srcBufYstart, 0, 0);
The result is wrong.
I guess some parameter is not right,I am wondering how to set srcStride and dstStride?
Will you help me?
Thank you.

Hi,
My customers are very interested in AM65xx series. They want to design without a heat sink.
Can it be used without a heat sink?
If possible, would you tell me the restrictions.
For example, A53-Core operates at 400MHz , limited the peripherals.

Hi All,
In my custom H/W, ADC is connected(ADS131E04) over McSPI0, and DRDY pin of ADC is connected to GPIO0 pin 18
I want to transfer data from ADC to CPU using GPIO event trigger(DRDY) using DMA
I configured DMA event 22(GPIO DMA event) and set destination address as McSPI0 TX FIFO.
I can see only 2 bytes transferring when DRDY pin go low, but my total byte count is 15.
Am I missing something in configuration?
Please assist me on this, Thanks for help in advance:)

Hi,
Is it possible that sometimes in Sgx3DsrvLink_tskMain at OSA_tskWaitMsg will wait message for a abnormally long time,
maybe 1~10 minutes,
and then receive the message again,
my customize usecase like below,
the links that was crossed out by black was taken off,
In particular, this situation often occurs in software versions where the alg links require more computation,
also usually occurs in 720p/25fps instead of 720p/30fps vedio format.

Hi,
Would you tell us about the Cortex-R5F core on the AM65 series.
I think
Cortex-M4F (MSP432) <Cortex-R5F (AM65xx) <Cortex-A8 (AM335x)
Would you tell me if there is a document on performance (DMIPS/MHz) etc.

Part Number: TMS320C6678
Hello experts,
I have a strange error case.
We have a nice application running on our custom board with several C6678, running like a clock. TI-RTOS is used.
One core has one task which is waken up every second (using a timer) that does some Ethernet UDP calls then sleeps.
We found an error in the code of the task : a variable was incremented and it shouldn't be. So we removed the instruction
And that's when all hell breaks loose
--> now we get an exception fetch packet error systematically.
--> it's really a 1 line change from working to not working
first I suspected a stack overflow: I checked with ROV : all modules are fine, tasks have enough stack.
Then I put a breakpoint in TI sysbios HWI1 which is the handler that manages exception and looked at the core registers
I have
IERR = 0x1 --> Fetch packet exception
NRP = 0x0 unfortunately
B3 = 0x804C4C --> I looked in the memory browser it corresponds to the TI code for ti_sysbios_knl_Task_schedule__I
We also have system analyser setup for this core
Here's what it is looking like when all is working
when we have the exception, sorry I don't have the capture but it looks like this
--> so my current understanding is
The core is in the "stack test" task. A semaphore pend occurs, triggering the task scheduler which crashes.
Using system analyser and ROV we know that this semaphore is from a GateMutex. Problem is: I don't know where it comes from as we don't use Gate mutex directly.
we use multicore gates (GateMP) with GateMP_LocalProtect_TASKLET as local protect so it probably comes from here.
Also looking at the memory map differences, we see that fardata is split in two, and some objets are moved (such as ti_sysbios_gates_GateMutex_Object__table__V)
below file OK
(Please visit the site to view this file)
below file KO
(Please visit the site to view this file)
--> do you have any ideas what could cause this ?
remember it's a one line difference in the code
Thanks

Hi all,
Customer current use .btbl .rmd method for boot. They use the internal ram only.
But now customer want to run the program on external DDR. So I want check if TI have the demo of the sbl for C6657/6678?
Or do you have any other suggestion about this requirement?

Hi Champs,
We would like to confirm "memory" ,"selection" when we build C66x core base program.
When we create large global variable area ："static unsigned char s_result[1226908];",
const area was separated i.e. const0 and const 1.
However, when we decrease this number as "static unsigned char s_result[1045000];" , const area didn't separate.
Do you have any threshold value to separate ".const" area ?
