Part Number: AM5728 Tool/software: Linux Hi, a customer notices the non-deterministic mapping of physical gpioX_Y to /sys/class/gpio/gpiochipXXX virtual files. In previous kernels like Linux 4.1 there was a deterministic mapping. But if one looks at the mapping in Linux 4.4, the mapping to physical address of GPIO modules seems to be random. root@am57xx-evm:~# ls -l /sys/class/gpio/ --w------- 1 root root 4096 Mar 30 00:56 export lrwxrwxrwx 1 root root 0 Mar 30 00:56 gpiochip0 -> ../../devices/platform/44000000.ocp/4ae10000.gpio/gpio/gpiochip0 lrwxrwxrwx 1 root root 0 Mar 30 00:56 gpiochip128 -> ../../devices/platform/44000000.ocp/4805b000.gpio/gpio/gpiochip128 lrwxrwxrwx 1 root root 0 Mar 30 00:56 gpiochip160 -> ../../devices/platform/44000000.ocp/4805d000.gpio/gpio/gpiochip160 lrwxrwxrwx 1 root root 0 Mar 30 00:56 gpiochip192 -> ../../devices/platform/44000000.ocp/48051000.gpio/gpio/gpiochip192 lrwxrwxrwx 1 root root 0 Mar 30 00:56 gpiochip224 -> ../../devices/platform/44000000.ocp/48053000.gpio/gpio/gpiochip224 lrwxrwxrwx 1 root root 0 Mar 30 00:56 gpiochip32 -> ../../devices/platform/44000000.ocp/48055000.gpio/gpio/gpiochip32 lrwxrwxrwx 1 root root 0 Mar 30 00:56 gpiochip504 -> ../../devices/platform/44000000.ocp/48070000.i2c/i2c-0/0-0058/48070000.i2c:tps659038@58:tps659038_gpio/gpio/gpiochip504 lrwxrwxrwx 1 root root 0 Mar 30 00:56 gpiochip64 -> ../../devices/platform/44000000.ocp/48057000.gpio/gpio/gpiochip64 lrwxrwxrwx 1 root root 0 Mar 30 00:56 gpiochip96 -> ../../devices/platform/44000000.ocp/48059000.gpio/gpio/gpiochip96 --w------- 1 root root 4096 Mar 30 00:56 unexport Could you help me understand how the allocation happens?

Hi Kemal, This issue is becoming a high priority issue for me, and I am starting to feel the pressure and requests for ETA, etc. from above. Going back to my original problem report. I was able to get nginx and openssl and compile them with certain mofidication, meaning modifying the 64 bit max numbers to a 32 bit. but unfortunately ssl did not operate correctly for me. Based on your original instructions, bitbake should have the whole thing for me automatically but it does not. How is the 64 bit max number issue resolved when bitbake is used? Maybe I can apply to same resolution to my own compile steps ... Regards Ahmad

Starterware CCS projects for AM437x were only supported in SYSBIOSSDK-IND-SITARA . TI has stopped providing free support for SYSBIOSSDK-IND-AM335x on 31 March 2017 as you can see from the notification here: e2e.ti.com/.../580869 We are currently supporting development only with Processor SDK RTOS and PRU-ICSS-INDUSTRIAL-SW . We recommend that you migrate to this software baseline to get support on TI E2E forums. Processor SDK RTOS support for bootloaders is described here and we are happy to support this baseline. processors.wiki.ti.com/.../AM437x Regards, Rahul

Part Number: PROCESSOR-SDK-AM57X Tool/software: Linux Hi, I have a customer who is interested in UDP throughput of Sitara devices with Linux SDK. We found below Wiki site and it shows some data. http://processors.wiki.ti.com/index.php/Processor_SDK_Linux_Kernel_Performance_Guide?keyMatch=performance&tisearch=Search-EN#UDP_Throughput But it is not clear number of A15 cores used for AM57xx (1 or 2). And how much CPU load is needed. (For TCP Throughput, CPU load is shown) Could you provide the information ? Thanks and regards, KoT

Hi Cvetolin Shulev-XID ， Yes, I know this is incorrect attidude to USB storage, but I can't guarantee the behaviour of our customer. So it is better to fix this bug... By the way, when this bug appear, if I do several unplug/plug operations, the USB storage will come back to Win7 finally...

At Linux Core U-boot User's Guide, To use nand use commands of 'mtdparts', 'nand erase.part', 'nand write'. But, 'U-boot' of omapl138 have a problem of MTD. 'mtdparts' command make blow messages (have none mtd information). For reference, mtd on Linux looks fine like blow. How to use nand for u-boot & kernel in omapl138-lcdk? How to add nand mtd partition to u-boot of omapl138-lcdk? thanks.

Hello, It seems like the ducati adds this 8 extra lines. I tried with ducatih264dec I see the same in the log file as for ducatijpegdec. It is not clear to me when you are observing this seg.fault. I tried with pipeline : gst-launch-1.0 filesrc location=1.mjpeg ! jpegparse ! ducatijpegdec ! vpe ! 'video/x-raw,format=(string)NV12,width=1280,height=720' ! kmssink /GstPipeline:pipeline0/GstVpe:vpe0.GstPad:sink: caps = "video/x-raw\,\ format\=\(string\)NV12\,\ width\=\(int\)1920\,\ height\=\(int\)1088\,\ framerate\=\(fraction\)1/1\,\ drm_mem\=\(boolean\)true\,\ max-ref-frames\=\(int\)1" /GstPipeline:pipeline0/GstVpe:vpe0.GstPad:src: caps = "video/x-raw\,\ format\=\(string\)NV12\,\ width\=\(int\)1280\,\ height\=\(int\)720\,\ framerate\=\(fraction\)1/1" In this case the vpe perform scaling and I do not observed any problem on my side. 1.Please confirm "scaling" use case is working on your side. 2.Do you observe seg fault in use case NV12 -> YUY2 for example. As you could see the low level vpe driver supports more formats compared to gst-vpe which supports only: video/x-raw format: NV12 width: [ 1, 2147483647 ] height: [ 1, 2147483647 ] framerate: [ 0/1, 2147483647/1 ] video/x-raw format: YUYV width: [ 1, 2147483647 ] height: [ 1, 2147483647 ] framerate: [ 0/1, 2147483647/1 ] video/x-raw format: YUY2 width: [ 1, 2147483647 ] height: [ 1, 2147483647 ] framerate: [ 0/1, 2147483647/1 ] on the sink and src. 3. Do you observe the error only in case NV12->RGB(the patch) that you attached? BR Margarita

I have attached mine (Please visit the site to view this file). You can use it. About your build try on different host or virtual machine. You have the two sources, compare them.

Following code is working smoothly for me: PWMSSModuleClkConfig(1); // for EHRPWM1 and EQEP1 // initialisation HWREGH(SOC_EQEP_1_REGS+QEP_QDECCTL)=0x0800; HWREGH(SOC_EQEP_1_REGS+QEP_QEPCTL) =0x1038; HWREG(SOC_EQEP_1_REGS+QEP_QPOSMAX) =0xFFFFFFFF; HWREG(SOC_EQEP_1_REGS+QEP_QPOSINIT)=0x7FFFFFFF; HWREGH(SOC_EQEP_1_REGS+QEP_QCAPCTL)=0x0000; // enable clock HWREG(SOC_PWMSS1_REGS + PWMSS_CLOCK_CONFIG) |= PWMSS_QEP_CLK_EN; // Pin MUX for QEP MUX_VAL(CONTROL_PADCONF_LCD_DATA13, (IEN | PD | MODE2 )) MUX_VAL(CONTROL_PADCONF_LCD_DATA12, (IEN | PD | MODE2 )) // reset counter HWREGH(SOC_EQEP_1_REGS+QEP_QEPCTL) =0x10B8; HWREGH(SOC_EQEP_1_REGS+QEP_QEPCTL)=0x10B8; // reset MOTF counter, does not matter when no MOTF is used currQEPosition=HWREG(SOC_EQEP_1_REGS+QEP_QPOSCNT)-0x7FFFFFFF; Finally currQEPosition contains the quadrature encoder count - so calling the last line repeatedly should be your solution.

Part Number: AM3351 Tool/software: Starterware I am using lwip lib and building a ftp server. But, TCP_CONNECT() call back function is never called, as of that, I am not able to do tcp_connect() post tasks. I read few articles in which people have mentioned that i need to call sys_check_timeouts() function periodically. So the problem is sys_check_timeouts() function is calling sys_now() which is not yet implemented. Here sys_now() is giving current time or equivalent to that. My question is how to implement this function which returns current time ?

Thanks a lot qxc for your reply! i am going to test it as soon as possible, but if it is no problem for you, could you please clarify some issues i have with your code, for my better understanding? Firstly, i have noticed that you reset the counter twice, is that a mistake or does it serve a purpose?Or do i have to reset it more than once, maybe after some specific conditions? Moreover, could you explain to me why you abstract 0x7fffffff from QPOSCNT value? Also, you have used the MUX_VAL function...which i am not sure i can find somewhere in starterware..is it a custom function you made?Is it like GpioPinMuxSetup? I am truly thankful for your help!!!

Segmentation fault : obo = omap_bo_new_paddr(odev, stride * height, (uint32_t)pbuffer, OMAP_BO_WC); omap_bo_get_name(obo, &gemname); omap_bo_new_paddr return val is 0 and run omap_bo_get_name() will have Segmentation fault

Resetting of the counter does not have to be done twice, this happened because I simply copied my existing code. 0x7fffffff is specific to my application but may be useful for you too - when currQEPosition is a signed integer and your encoder starts counting in reverse direction, you will see negative position valius too. The MUX_VAL functions indeed are related to pin-muxing, when you do not have enabled them as inputs for eQEP, you will not receive any pulses for counting.

Hi Gunter, This is with latest TISDK or a community kernel release? I know there is such issue with AM437x, but AM572x was fine.. I will take a look & update. Best Regards, Yordan

Hi, Do you have the prvr kernel module installed? Can you run lsmod & share the output? Best Regards, Yordan

[quote user="Michel Catudal"] It looks to me like very early in the process it cannot access the micro SD, perhaps it is not turning the voltage on correctly. Our hardware doesn't work if the voltage for the micro SD is less than 3.3V. I set the device tree to not support 1.8V for the mmc What would force the voltage below 3.3V? We use a similar PMIC as the one on the automotive evm but do not have something to switch the power off outside of the PMIC. [/quote] It might be HW problem of your custom board. So I have the below question. I assume you connect your SD card to DRA72x MMC1 interface. MMC1 IO buffers are powered by DRA72x VDDSHV8 power domain. What is the power source of your VDDSHV8 (MMC1 power domain)? Regards, Pavel
