Part Number: am5728 Tool/software: Linux I'm working with ti-sdk-03.03.00.04, installed on sitara am5728 EVM. I need to take screenshot of Qt app, launched in Weston. I've found screenshot tool in pre-installed binaries. In this thread mentioned, that it reads fb device and saves readed data into bmp file. But when I'm trying to open file, generated by this tool, I'm seeing only black screen with random white pixels near the bottom of the picture. How can I take a screenshot by this method correctly or in another way?

Forum Post: Linux: DM3730 UART3 download x-load.bin problem
Tool/software: Linux Customer inquiry; I am trying to get the 3730 to boot via its UART3. Just after power-up, the Boot ROM correctly sends its ASIC ID, and we respond with the image file size (32-bits Little-Endian) followed by the x-load.bin raw image file. That much goes smoothly, but the 3730 never comes up,it's mean that the x-load.bin did not execute ,I don't know where the mistake came from。x-load or pserial. my ways is use the pserial download the x-load.bin and ukermit download u-boot.bin

Forum Post: Linux/AM3352: How to Select LCDC Clock Source and Set the DISP PLL Parameter on AM335x
Part Number: AM3352 Tool/software: Linux Hi Expers, MPU: AM335x Boaed: Customer'ss board (Refer to Beaglebone Black) OS: Linux (SDK 7.0) Customer is porting LCD module on AM335x customer's board, required PCLK is 33.3MHz. We understand Device Tree can set PCLK by setting "display-timings" parameters. However, set "clock-frequency = ;" in display-timings should make "LCD_PCLK" pad (V5) output is 33.3MHz, but we measure V5 pad and we got the frequency is 38.4MHz. We discussed and done the experiment, we found that TI SDK default LCDC clock source is "PER PLL CLKOUTM2" (192Mz), so LCDC Clock divisor can't get accurately 33.3MHz by setting clkdiv register. Then we use devmem2 tool to set registers and make "DISP PLL CLKOUTM2" output is 200MHz and use this clock as LCDC clock source, we can get accurately 33.3MHz for LCD_PCLK by setting LCDC Clock divisor is 6. Anyway, we can use devmem2 tool to set the registers and get the required PCLK durring system runtime. Now we want to make this register settings in the LCD drivers than system can set the appropriate paramter during the initial process. Here is the question: We can't find where the Kernel source code set the LCDC clock source and where to set the "DISP PLL CLKOUTM2" multiplier/divider factor. Can anyone tell me the hit point how to apply the changes to Linux Kernel. Best Regards, Wayne Kuo

Forum Post: RE: Linux/TVP5158: TVP5158 Interleaved mode support
Hi, I have an additional question related to this. How is the channel number passed on. If it is the line interleaved or pixel interleaved mode. How does the application know which buffer belongs to which channel. Can we maintain the line/pixel order for both the line/pixel interleaved modes. suppose: channel-1 - ntsc-cam-1- turned on third channel-2 - ntsc-cam2 - turn on first chanel-2 - ntsc-cam3 - turned on second channel-4 - ntsc-cam4 - turned on fourth Whether the pixel/line order always maintained constant so that we can find at app level which buffer belongs to which camera. thanks,

Forum Post: RE: Linux/TVP5158: TVP5158 Interleaved mode support
Hi Sriram, Channel number is part of the SAV/EAV code and driver provides details about which buffers stores which channels. Essentially, you need to enqueue buffers to appropriate channels in order to capture them. So App knows that which buffer is enqueued to which channels.. Regards, Brijesh

Forum Post: RE: Linux/AM5728: Ducatijpegdec GStreamer Plugin adds 8 extra lines of decoded image, produces incompatibility issue with VPE
Hello, [quote user="Tom Wallis"]This may appear to be only on 'live' sources. In our final application we're going to be working with udpsrc, perhaps there is an issue with how ducati handles that type of source.[/quote] You could replace udpsrc with videotestsrc and check the behavior. I also would recommend the sync=false to be set in the videosink element(no matter is it kmssink/waylandsink etc). BR Margarita

Forum Post: RE: Linux: Possible to flash NAND from Linux userspace?
Hi Michael, You are looking wiki for very old BeagleBoard OMAP3530 , not for BeagleBoneBlack AM335x. There is no BeagleBoard Black board, it is BeagleBone Black. I would recommend you to check again what is your TI device (OMAP35x, AM335x, etc) and to which board exactly (BeagleBoard, BeagleBone, BeagleBone Black) your custom board is based. In AM335x device (BeagleBoneBlack and BeagleBone), we can flash SPL/MLO and u-boot in NAND from user space through the MTD utils (commands flash_eraseall, nandwrite), see the belwo wiki pages for more info: processors.wiki.ti.com/.../Sitara_Linux_Training:_Boot_Time_Reduction processors.wiki.ti.com/.../Linux_Core_NAND_User's_Guide processors.wiki.ti.com/.../Mtdutils processors.wiki.ti.com/.../MTD_Utilities I would also suggest you to work with the latest AM335x TI SDK ti-processor-sdk-linux-am335x-evm-04.00.00.04 Regards, Pavel

Forum Post: Linux/AM5728: systemd (tcgetattr(), printf() ) issue
Part Number: AM5728 Tool/software: Linux hello, We use " AM5728 , PSDK 04_00_00_04". Currently, we have used systemd to run the program we developed automatically. However, there are some problems with the systemd operation. I would like to get help on this. 1. init fail tcgetattr() The program we developed should receive keyboard input from the terminal. However, if executed with systemd, init fails with tcgetattr () function. Are there restrictions on using the function in systemd? If you run the program directly from the console, it works without problems. There is no problem when executing directly from the terminal. root@am57xx-evm:/#systemctl start test.service => Run fail. root@am57xx-evm:/#./test => Run ok. 2. printf() Debug message output. When I run the program with systemd, the text (hello world) is not output. This is our example Systemd service. test.service ======================================= [Unit] Description= start test PG [Service] Type=simple ExecStart=/etc/init.d/helloworld.sh StandardOutput=journal+console [Install] WantedBy=multi-user.target ======================================= helloworld.sh ======================================= echo "Hello World!!!" ======================================= root@am57xx-evm:/#systemctl start test.service =>No display message root@am57xx-evm:/#./helloworld.sh Hello World!!!" Could you tell me how to do this? There is no problem when executing directly from the terminal. 3. Can not use init.d process? We have init.d still useful. Thank you.

I'm not familiar with this Linux distribution because this forum is focused on the TI's Linux release as Processor SDK for example: www.ti.com/.../PROCESSOR-SDK-AM335X but in general it is not good idea to disable interrupts for the stability of the whole system. I suggest you to try to increase SPI FIFO buffers. BR Tsvetolin Shulev
