Is it possible to get a copy of an image file with the demo software for this board, or a replacement SD card? I lost the one that came with my system.
Thank you

AM5728: C66x reducing pipeline stalls when using L1 configured as cache and accessing data in L2 SRAM
Part Number:AM5728
I am trying to implement time critical algorithm on C66x that requires to process about 32kB of data. The algorithm is relatively simple and clearly bonded by the width of data bus. Because in the target environment there are also other, more complex tasks running in the background, L1 memory has to be configured as cache only. L2 is configured as 128kB of cache and remaining part as SRAM. To better analyse the issue that I am observing, I am using the following assembly code:
SPLOOP 2 LDDW *AYPTR++[2], AH || LDDW *BYPTR++[2], BH LDDW *AYPTR++[2], AH || LDDW *BYPTR++[2], BH SPKERNEL NOP 9
Before running this code whole content of L1 data cache is invalidated. The trace for the SPLOOP is below.
It is easy to notice a lot of pipeline stalls occurring when access to the next L1 cache line happens. The stalls actually takes more time than actual processing. Is there a way to improve performance for this kind of algorithm? I know about the touch function, but it gives mixed results where no all data are evicted between consecutive runs. I also assume, that to use IDMA I need to configure L1 as SRAM? What else can be done to reduce the number of cycles wasted on pipeline stalls?

Linux/AM5728: SPI communication
Part Number:AM5728
Tool/software: Linux
Hi,
I am interfacing 2 SPI devices with AM5728.which are connected to same SPI bus.Device 1 is having driver and Device 2 is not having any device specific driver. i want to access them one after the other.
Is it possible to access the device 2 which is not having any driver?
whether the device 1 which is having the driver will always make bus busy?
If the device 1 occupies the bus from driver i will not be able to access the device 2 .Is there any way to access the device 2?

TDA2PXEVM: [OpenGL] how to run multiple OpenGL renders(windows) into one screen
Part Number:TDA2PXEVM
Hello All:
As we discussed before that VisionSDK is not support the QT environment.
We have the AVM which is developed by QT that we need to porting to VisionSDK.
This AVM will create two QT windows(part of the whole screen) that each window will run OpenGL to render the output to parts of the screen.(Eg. 50%s for each window),
please see the diagram as following 
For now, without QT window support, how can we:
1. Create multiple window(or surface) for each OpenGL?
2.Each OpenGL render only render part(50%) of the screen?
Any suggestion is appreciated!

Since, it is showing the device is not created at /dev/misc/rtc, thus I modified the .dts file to add the following lines:
/* fixed 32k external oscillator clock */
clk_32k_rtc: clk_32k_rtc
{
#clock-cells = <0>;
compatible = "fixed-clock";
clock-frequency = <32768>;

&rtc {
clocks = <&clk_32k_rtc>, <&clk_32768_ck>;
clock-names = "ext-clk", "int-clk";
status = "okay";
};
But still to no avail. Please provide your suggestions to get the linux to read proper RTC time.

be available for Video Frame, please correct me if I have made some mistake.

Hi Team,
I met one software issue with a RMII design on customers' board. Please help to check as below.
Hardware platform:
Customers’ product board with RMII design.
we have designed an board based AM3357, according to ICEV2.
the difference between our board and ICEV2 is that we have three ethernet port: 2 for PRU-ICSS and 1 for CPSW. there is no pin reuse in our board.
the PHY in our board is
Software environment：
in Uboot and Linux environment， RMII is set by device tree, the port can work, we can ping it success. so there is no hardware problem in our board.
but in RTOS environment, it can't work!
the sdk that we are using is ti-processor-sdk-rtos-am335x-evm-05.00.00.15-Windows-x86-Install
experiment
firstly, we modified the am335x_icev2_pinmux_data.c. the new CPSW discription is shown as

then we executed the gmake in the cmd window, when finished we import the project NIMU_BasicExample_icev2AM335x_armExampleproject and rebuild it.
after load the program and run we got the following result
It seems that the connection is successed, but the ping form our host computer is failed!
the program is shown as:

OMAP3530: OMAP3530 - PMIC
Part Number:OMAP3530
I have adesign where an OMAP 3530 is powered from a PMIC TPS65920.
The VMMC output from the PMIC is very low and the part gets overheated. There is no short-circuit on this output.
The rest of power rails to the OMAP are O.K.
Using an oscilloscpe, I observed a periodic signal of about 200uS Low time and a period of about 7mS from the OMAP SYS_NRESWARM to the PMIC NRESWARM input.
In addition, when the system is powered-up, the OMAP UART3 outputs the 40W string to the terminal, but with a slightly lower baud-rate than 115,200 (about 110,000bps).
Please advise.

AM5726: About slew rate setting of Pad Configuration Registers
Part Number:AM5726
Hi,
I have question about Slew Rate control for DDR3.
Q1: What is the SR control register prepared for the purpose?
What effect does this register have?
Q2: If it is set to Fastest (SR [2:0] = 0x0) on my customer board, the signal quality deteriorated and failed the DDR3 compliance test.
Although it is stated that the default setting (Fastest) is used for the data sheet, can we change this according to customer's use?
Q3: The SR[2:0] registers can be changed, why is not it guaranteed except the default setting?
Best Regards,
