Hello,
We're having the TCI6630K2L SOC and we want to use the Receive Accelerator (RAC ). It will be helpful if someone can share the example application code and any relevant documents.
Thanks & Regards,

Hello,
Now using 10kohm PU register on I2C lines, based on VOL and Idrive specification in data manual and EVM's I2C pull-up register value.
However, the actual measurement on the board, tr timing value was 600nsec and not meet the fast speed tr specification (max 300ns).
Is there any recommended PU register value of I2C (fast speed)?
Regards,

Hi,
I am using the AM5728 PROCESSOR in our board.All the PMIC(TPS6590378) outputs are coming correctly within tolerance and also checked for the clk in for OSC0,1.
Both the clocks are OK. Then i connected UART3-RS232 converter output to the PC.I have done the basic setting for the serial port Baud--> 115200,data size--> 8,parity--> none etc.
There is no reply/reponse from the processor.
Is any other thing i need to check?
Is UART3 respond from the ROM boot loader or some boot image file require?
Please provide the feedback and related link .
Thanks in advance.

Hi, I have two questions below for software pipelining.
1) Why didn't the file xx.se66 occur for my linear assembly file named xx.sa after I using the opt "-MW -k" to compile. so I cannot see the information of software pipelining.(but when I use xx.cpp, there is no such problems).What should I check to my compile opts?
2) which is better between a and b.
a. ii = 4 Schedule found with 9 iterations in parallel.
b. ii = 4 Schedule found with 3 iterations in parallel.
3)which is better between c and d.
c. ii = 4 Schedule found with 9 iterations in parallel.
d. ii = 3 Schedule found with 9 iterations in parallel.

Hello Champs,
Customer has configured dsp clock and reset in uboot (uboot has no DPLL configuration code). If he added the DPLL code, the ccs could not be connected to the board again, it prompted below error message.
66xx_DSP1: Error connecting to the target: (Error -1144 @ 0x0) Device core is hung. The debugger attempted to recover debug control, but was unsuccessful. Power-cycle the board. If error persists, confirm configuration and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 7.0.100.0)
The emulator is okay. If he didn't add the DPLL code, ccs could be connected to board, but the dsp code could not boot successfully, if modifying the DPLL register in memory browser, the dsp could boot.
In summary(uboot has configured the DSP clock and reset):
1. uboot, not add dsp dpll code, ccs could connect to dsp core, but code run incorrectly without DPLL configuration
2. uboot + dsp dpll code, ccs could not connect to dsp core most of time, it could connect to dsp core and run correctly only several times.
3. uboot, not add dsp dpll code, ccs could connect to dsp core, modify the dpll register, dsp code run correctly.
What's the problem? Is it related to PCIe?
Thank you.

Hi team,
I use the AM3354's lidd mode with the ra8875 lcd controller, which can already generate fb0 in the /dev/ folder and display the rootfs screen, but in order to distinguish my ra8875 driver, in the device tree, I changed the LCD name from "tilcdc" to "ra8875lcd".
I want to further display the graphics made by QT creator on the LCD, so I chose SDK-04.01.00.06, but there are some problems.
I posted some messages executed in SDK-04.01.00.06 below. Can you please assist in the analysis?
By the way, I can display the Matrix screen on the host side.

Hi,
we are using AM3352 based custom board with nand Micron MT29F4G08ABBFAH4. we were using the 4.14.38 Linux kernel and 2018.01 u-boot since long. board and software works fine here.
And we try to upgrade the Linux kernel to 4.19.20 with same board and u-boot, we are getting omap2-nand 8000000.nand: uncorrectable bit-flips found and that leads to ubi0 error: ubi_io_read [ubi]: error -74 (ECC error) while reading 13 bytes from PEB.
Finally the rootfs mounts ro. Next boot ubi mount, gets failure due the previous ecc errors.
(Please visit the site to view this file)
I attached the boot log, please give some input on those errors
I need to know ti-processor-sdk-linux-am335x-evm-06.00.00.07 prebuilt binaries is working with am335x-evm board nand boot?. Here i couldn't verify with our custom board.

Hi TI,
I have few question regarding post image processing on tda2.
1. How to use vlib within the tidl_postproclink,c?
2. Which function of vlib can be used to extract the information of individual class mask. What I am looking for is something similar to cv2.inRange function in Vlib?
3. Is there any function to find the contours as well in vlib?
Thank you.
With best regards,

Writing failures occur when using nandwrite instructions in MTD util tools
The NAND flash GPMC pinmux settings are as follows
When I erase and write Flash, I use an oscilloscope to measure the Wpn pin, which is always high level without write protection.
But after calling nandwrite to write flash, there are a lot of errors, as shown below.
So I added some test code to the driver of kernel, found that it was often considered to have write protection at the function nand_check_wp. What is the reason for this phenomenon?

Hello,
I have adapted/ported the Profibus slave example provided with the PRU-ICSS Industrial Software for Sitara processors to work in the BeagleBone Black board.
I think it might be a good educational exercise (to learn about industrial communications, RTOS,...) and I was thinking of posting instructions on Github.
But I have a concern regarding the export control restrictions that apply. I'm actually a bit confused because according to the license included with the code redistribution is allowed as long as the copyright notice and non-endorsement conditions are retained.
The question is then: can I publish the code of the Profibus example itself (original or with modifications)?
To make the example work on the BBB I had to modify the source code of the Ti-RTOS PDK, but since that is part of the Processor SDK I'm assuming no restrictions apply on that front.
I do understand there are commercial reasons for TI not to actively support (or at least include the source with the PDK) the Profibus or other industrial communication protocols on the BBB (I'm joining the dots here and I hope not overstretching them but I'm guessing the BBB is not at all a competitor to the Sitara development boards for which the examples are intended so not much profit would be sacrificed there).
On the other hand, Profibus hardware is very expensive and I think there would be an audience for educational purposes. I'm wondering why there is no support for these examples on the BBB...
Thank you in advance for your feedback on this.
