Hi,
I found those pins AE7，AE8,AE10,AE11,AE12, AD1,AD2 AD7 connnected some signals and parts on the “Pg20: Secondary RTC Osc/Ctrl” on the AM437X_GP_EVM_3K0006_REV1_4A.DSN， but on the AM4378 datasheet ,those pins are reserved.
Can I let those pins open in my design?
Best wishes!

Hello!
I am extending the usb driver code that came with the k2g pdk code so that I can plug in a usb MIDI controller device to the board. The version of the pdk I am using is 1.0.7.
When I add printf statements to the usb driver code, the code that was cloned from pdk_k2g_1_0_7\packages\ti\drv\usb, my program crashes if I use formatted strings like this:
printf("Here is a value: %d!\n", value); // This prints the string to the console and then crashes
My program prints to the console as expected: "Here is a value: 0!" and then crashes.
It works fine if the the string is not formatted with an argument. This works fine without crashes:
printf("Here is a string, no values!\n"); // This works, no crashes!
I am building the usb code outside of ccs, using gmake. My main code that links the usb library is built with ccs and printf works as expected. I am wondering what is causing this behavior. Is the usb code using a different printf function? Is there a memory access issue going on? How can I tell?
Thanks for your help!

Hi, All
I have two types of board with OMAPL137. One of the two types, is designed without "Power-on sequence."
At first both types were fully functional but, few monthes later, one without the "Power-on sequence" had a common problem.
Communicating with SDRAM failed and I think EMIFB_CLK is the main cause, could there be other cause?
Does not keeping the boot sequence cause similar problems? Like LATCH-UP?

Is it possible to know the Configuration of the device and initialization of primary peripherals in ROM boot code and how the code is written for searching the next bootloader.
I am also willing to know the boot sequence related flow(to which address is the ROM searching and where is the u boot actually present if a SD card is used for booting am5728 GP EVM )is happening in the hardware. Mainly where how the code is written to search for image files and where the ROM boot code has found the next bootloader( i want to know the address where it found ).
Is there any way to know the detailed process of booting the "AM5728 GP EVM" i mean where to find all these codes that are responsible for booting of board. I unable to understand what code files are responsible for booting the EVM board.

Hello Guys,
Actually i have used opencv application on AM5728 evm board and stream rtsp source.But it is too slow.
So, i decide to use hardware codec to convert video format. So, i have used VPE with gstreamer and testing.
Now, if i use "videoconvert" in gstreamer pipeline with filesink and pass that file to opencv. So, its work proper.
But if i use "vpe" instead of "videoconvert", then that file could not open by opencv.
I have used "command" as below:
1).gst-launch-1.0 -v rtspsrc location=rtsp://888888:888888@192.168.1.2:554 ! rtph264depay ! h264parse ! ducatih264dec ! videoconvert ! 'video/x-raw, format=(string)BGR, width=(int)640, height=(int)480' ! filesink location=video_test.bgr -v
2).gst-launch-1.0 -v rtspsrc location=rtsp://888888:888888@192.168.1.2:554 ! rtph264depay ! h264parse ! ducatih264dec ! vpe ! 'video/x-raw, format=(string)BGR, width=(int)640, height=(int)480' ! filesink location=video_test.bgr -v
Now, i am attaching 2 application which i have using.
In "g_opencv.cpp", i have using gstreamer pipeline and passing frame to the opencv.
In "objectdetection.cpp" application, i am trying to pass raw-data file which has been generated by gstreamer+vpe+filesink pipeline.
So, is there any other option which should i use or how can we solve this issue?.
I have also found that "facedetect" can be use with gstreamer to detect face, but when i execute "gst-inspect-1.0 facedetect", i got log as below:
root@am57xx-evm:~# gst-inspect-1.0 facedetect
No such element or plugin 'facedetect'

Hello Everyone,
I have some questions regarding the AMIC110 running as ESC together with the TSM320F28379.
- Does TI provide the SoftwareStack for the AMIC110 to work as ESC together with a Host-Controller
- is this SoftwareStack standalone Code or do we have to write additional code to make the amic110 interact with F28379D
- if it is standalone which PDI will be supported and where can I find documentation for this
- do we have to Flash the software stack onto the amic110 ourself or is it shipped pre-flashed?
- Does TI provide sample code for the Host controller to communicate with the AMIC110,
- if TI provides the Stack how much does it cost (per year, or once)? are updates included? (EtherCAT, Profinet)
- If the AMIC110 is used together with the TSM320F28379 the external Flash is not necessary, correct?
- How many Bytes of Process data can be exchanged with the AMIC110 together with F28379D when running 250µs EtherCAT cycle time
Thanks and regards.

Hello,
I'm about to build a new board, including an AM5728 and many high speed components (ethernet, USB3, SATA, wifi...). My concern is about the layout of the board.
I attached a picture with 3 differents topologies of Layout, and I would like to have some feedback to what topology is the best way to prevent any EMC/ESD disturbances.
The first topology with the guard ring is based on the AM57x eval board, but to be honest I'm not very confident with that.
Thanks in advance for your help and advices.

Team,
The USB DWC3 controller seems to be compatible with the USB 2.0 full speed (FS 12 Mbps) mode (according to TRM SPRUIHL7H section 16.1.1).
Is the driver tested for this use case? What USB HW is being used to validate the FS mode?
The back compatibility is important for our customer that use a specific USB 2.0 full speed (FS 12 Mbps) Wireless module.
Thanks in advance,

Hi TI Experts,
I have a question.
I am studying the boot method using XIP.
I would like to do the following SBL equivalent with XIPboot.

· Can I create XIPboot project with CCS?
· Is there any example project to be helpful?
I look forward to hearing from you soon.

Hi :
We are using am5728 to do some video capture , processing developments,
Now we use vip and vpe like this :
The buffer type of vip and vpe output is dma(in cmem), type of vpe capture is mmap . We get rgb pixel from vpe capture and display in qt . But when we start application, follow error is occur.
And the app is stop here. When we want to terminate it using CTRL-C， following kernel panic error show up.
Anyone can give some advice about this? or am i do something wrong about used vip and vpe together?
PS: we use sdk version is ti-processor-sdk-linux-am57xx-evm-04.00.00.04

Hi all,
I try to use i2c1 in u-boot. First, I enabled i2c1 as dts file like below:
&am33xx_pinmux {
i2c1_pins: pinmux_i2c1_pins {
pinctrl-single,pins = <
0x158 (PIN_INPUT_PULLUP | MUX_MODE2) /* spi0_d1.i2c1_sda */
0x15c (PIN_INPUT_PULLUP | MUX_MODE2) /* spi0_cs0.i2c1_scl */
>;
};
};
&i2c1 {
clock-frequency = <100000>;
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&i2c1_pins>;
};
When power my board, I can see i2c bus 1. But I can probe any address on this bus.
=> i2c dev 1
Setting bus to 1
=> i2c probe
Valid chip addresses: 18 68i2c_probe: pads on bus probably not configured (status=0x10)
i2c_probe: pads on bus probably not configured (status=0x10)

18: generic_18, offset len 1, flags 0
68: generic_68, offset len 1, flags 0
Bus 2: i2c@4819c000
When I try to read value of register as address 0x18
=> i2c md 0x18 0.1 0x00
Timed out in wait_for_event: status=0000
Check if pads/pull-ups of bus are properly configured
In the kernel, I can use i2c bus 1. Please give me some advances for this case. My u-boot version is 2016.11-rc3
