TMDXIDK5718: getting a delay while processing the data between two arm processors using TCP Socketprogramming
Part Number: TMDXIDK5718
In my project i am using two arm processors...one as Client and One as Server...i am sending the data from Client to Server using TCP/IP Socket Programming and i am processing the data at the server processor ...... i am taking the output at the server.....for example i am sending the audio data at the client and trying to receive the same data at server...
while receiving the data i am getting the Delay of 2 to 3 seconds(rough estimation)....
i am running the whole process on GPP....
1.Why Delay is coming
2.How can i reduce the Delay time ?
3.How can i calculate the Delay exactly ?
4.am i delay becuase of GPP ?

AM3351: Linux boot failure on custom board
Part Number: AM3351
Hi,
My customer using AM3351 reported boot-up issue on their board.
The software version is TI-PROCESSOR-SDK-LINUX-AM335X-EVM-04.01.00.06.
The board is custom and micro-SD boot is used.
There are a several failing pattern at boot-up.
a) Repeat “Starting kernel ...”
b) Stop at “random: crng init done” just after Arago Project logo.
c) Repeat “A start job is running for…”
d) Stop at “[FAILED] Failed to start Synchronize System and HW clocks.”
I will send you all 4 type logs as well as normal start-up log in separate e-mail.
Please review them and give your advice where needs to be checked.
Thanks and regards,
Koichiro Tashiro

AM3358: How to burn into custom board emmc from the already established the image of SD card.
Part Number: AM3358
Dear sir,
here i used this sdk "ti-processor-sdk-linux-am335x-evm-06.01.00.08" and i build all
MLO
u-boot.img
-----------------
zImage
am335x-boneblack.dtb
------------------------
and Modules installed rootfs
--------------------------------------------------
for custom SD-card : by using "create-sdcard.sh", i have created boot & rootfs partitions and copied above files properly.
after that inserted in to BBB board here it's working fine and i got login prompt : root@am335x-evm#.
when i remove my sd card and i checked again my kernel version it's not my custom kernel it's showing previous version.
so, now i want to let these all should be flash on-board eMMC. please tell me the procedure and
Thanks

DRA746: [Navigation]: Navigation is crashing and crash is triggered by eglSwapBuffer.

Could you please help us in analyzing this issue and also provide your inputs in generating the API call trace for navigation as in navigation multiple applications are involved and we can't use "
start_tracing.sh" directly for generating the call traces.

the DSPF_sp_fftSPxSP cost 1069 clks when N=128 and 1965 clks when N=256.
I run the test project provided by TI, D:\ti\dsplib_c674x_3_4_0_0\packages\ti\dsplib\src\DSPF_sp_fftSPxSP.
Even with all optimization level -o3 and --opt_for_speed level 5, I can only get 1159 clks when N=128 and 2119 clks when N=256.
Why I cannot get 1069 and 1965 with the provided project?

AM5728: USB2.0 LPM issue
Part Number: AM5728
In the previous thread, the USB driver software required patching since the AM5728 does not support USB2.0 LPM.
In the latest USB driver source code, it doesn't seem to check that the USB port (host) supports USB2.0 LPM before enabling USB2.0 hardware LPM.
https://elixir.bootlin.com/linux/v5.3.12/source/drivers/usb/core/hub.c#L4468
/*
* There are reports of USB 3.0 devices that say they support USB 2.0 Link PM
* when they're plugged into a USB 2.0 port, but they don't work when LPM is
* enabled.
*
* Only enable USB 2.0 Link PM if the port is internal (hardwired), or the
* device says it supports the new USB 2.0 Link PM errata by setting the BESL
* support bit in the BOS descriptor.

Should the above source code be changed to not enable USB 2.0 hardware LPM in all cases?
Are there any changes required other than the above source code?

AM4376: Configure frame sync of McASP
Part Number: AM4376
Hi,
We are using the AM437x ARM Cortex-A9 processor and are utilizing the McASP module for transferring I2S audio. Currently we are facing some problems and would need to configure McASP as clock master on I2S and to generate 25, alternatively 30, clock cycles per frame. For example, if we use a bit clock (XCLK) of 800 kHz, the generated sample rate need to be 16 kHz (16 kHz * 2 channels * 25 bits = 800 kHz).
Is there any way to accomplish this?
We have seen that transmit slot size (XSSZ in MCASP_XFMT register) is only configurable to 8/12/16/20/24/28/32 bits, but is there any way to still generate 25 clock cycles per frame even though data is only output on first 24 bits? Is there any padding configuration or similar?
We will be very thankful for a quick answer. Thanks!
Regards,
Magnus

TDA3XEVM: Capture upper 8-bits of monochrome RAW10 as U8
Part Number: TDA3XEVM
Hi,
We have some questions about the capture module of the TDA3.
We have some questions about the capture module of the TDA3.
We are using a monochrome image sensor using CSI2. These sensors work at RAW10.
We got a capture-CSI2-display-HDMI loopback example to work on the TDA3EVM but the captured image is stored in U16 format (i.e. stored in 10 bit LSB. upper 6 bits are 0)
Because our algorithm is optimized for working in U8. We would like to capture these monochrome images as RAW8 (i.e. shift right two bits) and store it in U8 format.
What we've tried:
- We've tried to store these as U8 by setting the packing to U8 in the CAL module but the lower 8-bits of the RAW10 are stored and there is no shift by 2. We might be able to compensate for this by lowering the gain in the sensor by 1/4 but we have not tried this.
- Use the ISP to convert it to YUV402 and use the Y component as this is stored as U8. However we do not understand the implication of the Bayer RGGB conversion forced upon the IPIPE module. We do not know how much quality degradation this will give us in the end.
We have the following questions:
- Is there a simple way of capture monochrome RAW10 directly from sensor and store these as U8 shifted right by 2. Would it be possible to configure a DMA to do this conversion?
- Is there a way of treating the incoming monochrome RAW10 without the Bayer filtering?
- How is the Bayer filtering affect our monochrome input?
- Is there any other recommended way of handling this?

66AK2G12: Clock tree tool mismatch
Part Number: 66AK2G12
Hi,
I am designing a board with 66AK2G12 and I am using Clock tree tool v.1.0.0.2 that allow to select this device and silicon revision 1.0.
For my purpose I need to obtain a 25 MHz clock signal on CLKOUT ball H23 for two Ethernet phy in MII mode. According to SPRUHY8I TRM, I can use NSS/IEP PLL that generates 1GHz clock signal, divided for 20 factor, obtain 50MHz. Through a 2 factor of division and the mux enable signal set to 1, I obtain 25 Mhz at the output.
Now I am checking with CTT if this choice is correct but I see that the division factor is 200 and not 20, 2.5 MHz clock signal reaches the CLKOUT pad and not 25 MHz.
Please can you confirm that this is an error on CTT and the TRM is correct?

AM5728: Junction temperature formula difference
Part Number: AM5728
Hello TI,
In the "Thermal Design Guide for DSP and ARM Application Processors" application report (link to the pdf below), the junction temperature equation seems to be different at two different places. In equation 2 and in equation 7, although they seem to refer to the same thing. In equation 2, you have Theta_CS*Theta_SA component and in equation 7 you have Theta_CS+Theta_SA component. I am assuming that one of it is a typo error. I would like to know which one is correct. OR if I am missing something then please let me know.
