Martin, The example in ISDK should work in CPSW mode with the define USE_CPSW_DRIVER. This has been tested. Can you verify the changes coming within the define? We have a workaround for SDOCM00105257 , which is also in place in the code. Regards, Vinesh

Forum Post: RE: U-Boot Hangs
HI Titus, We are using same DDR memory as EVM, the hw changes from EVM are we have used MMC3 for eMMC instead of MMC2, and addition of some serial ports only. NOR Flash we are using 128MB. But what can be the reasons for hanging at the hash functions? Please check the sequence where it exactly hangs i have mentioned in the question? Thanks & Regards Ganesh

Forum Post: RE: Application trigger on USB arrival
Hi Titus, Yeah we already had few discussions. I am trying to load the kernel driver and the application to access the kernel driver as well. In that case, I am facing issues like 1. Only absolute path is working in the shell scripts. (Like everything starts from "/home/" or "/") 2. I am not able to know the status of running application inside the shell script. 3. I am not able to get some trace prints. Right now am dumping in the file. (As echo "Error occurred in app" >/usr/log/mylog) Also is the same udev rules work for device removal as well ? Regards, Lyf

Forum Post: RE: NDK UDP sendto problem
Thanks Steve pObj->ipAddrRemote is from type struct sockaddr_in. I use only the IPv4 protocol. pObj is a pointer to the struct. And because of this i need the address for sizeof. OR? pObj->ipAddrRemoteLen = sizeof(&pObj->ipAddr_Remote); AND ipAddrRemoteLen is a int. Benedikt

Forum Post: RE: Not able to build HTTPSGET for Tiva C Series
Hi Steve, I am using cyassl v3.3.0 provided at www.wolfssl.com/cyassl-3.3.0.zip I tried with cleaning and Building Cyassl library again but still same problem persists. I am able to add ssl.h in #include and also able to access the function while writing the code. But it is giving issue at Build time only. Are there any compatibility issue or including path setting in Compiler setting? Not able to proceed further in this example. If you have any other sample code please share with me. Thanks, Bhavesh

Forum Post: RE: Not able to change Priority of task at run time nor able to create task dynamically
Hi Alan, Changed the TCPHANDLERSTACK to 2048 but it is still giving problem. If I created the task from Network Hook Function than it is able to create but while creating a task within other task its giving NULL handler. So its look like task can not be created in other running task, HWi, SWi or Timer. Even Task_SetPri() do not work. What is remedy for this? Currently got stuck at this point and if not able to get solution within a week than I might have to look for other options to achieve this. Can you please suggest me other way to achieve Task Handling. Thanks, Bhavesh

[quote user="Matti Kaasinen"] is there any documentation related to this M3 core?[/quote] Cortex-M3 ARM core manages entry and exit of various stand-by and deep-sleep modes. It is only used for power management. See AM335x TRM, section 8.1.4.6 Functional Sequencing for Power Management with Cortex M3. The binary and source code are available at: [quote user="Matti Kaasinen"]Can it be used to something else than power management?[/quote] No, it can not. BR Pavel

Forum Post: RE: Has AM335x_ADC_Driver interface changed in linux 3.14?
Titus, I checked kfifo help (below). It seems pretty impossible to disable. Virtually anything enables it. CONFIG_IIO_KFIFO_BUF: A simple fifo based on kfifo. Note that this currently provides no buffer events so it is up to userspace to work out how often to read from the buffer. Symbol: IIO_KFIFO_BUF [=y]; Type : tristate Prompt: Industrial I/O buffering based on kfifo Location: -> Device Drivers -> Industrial I/O support (IIO [=y]) -> Enable buffer support within IIO (IIO_BUFFER [=y]) Defined at drivers/iio/Kconfig:28 Depends on: IIO [=y] && IIO_BUFFER [=y] Selects: IIO_TRIGGER [=y] Selected by: AD5933 [=n] && STAGING [=n] && IIO [=y] && I2C [=y] || ADE7758 [=n] && STAGING [=n] && IIO [=y] && SPI [=y] && IIO_BUFFER [=y] IIO_SIMPLE_DUMMY_BUFFER [=n] && STAGING [=n] && IIO [=y] && IIO_SIMPLE_DUMMY [=n] || IIO_TRIGGERED_BUFFER [=n] && IIO [=y] && IIO_BUFFER [=y] ||TI_AM335X_ADC [=y] && IIO [=y] && MFD_TI_AM335X_TSCADC [=y] There must be some other reason why "mode" node does not exist in sysfs. I tried also that "drivers/staging/iio/Documentation/generic_buffer.c". It has changed so much that patch presented in wiki did not work. However, I made the changes patch had to make genefic_buffer.c work without triggers. Well, it did not work. Application returned always -1 as return value (=read_size) from reading from /dev/iio:device0. Is there anything I could debug here more? Regards, Matti

Hi, Please compare the kernel bootup logs of old and new and see if you get any hints from that. [quote] However, I can't find /sys/bus/iio/devices/iio:device0/mode from sysfs for changing sampling mode. Do I miss something essential from the document or has interface changed? If so, could someone describe how to use it now? [/quote] Just "mode" entry alone not able to get or whole entry ? I presume that you have enabled SYSFS and mounted it.

Forum Post: Examples of L2 Cache Configured as SRAM on AM437x
I'm having difficulty using the L2 cache as RAM on the AM437x. My understanding is the device powers up with L2 cache disabled and the RAM is powered and clocked. I've defined section in the memory but I'm unable to load code through the emulator to those locations. I'm also not able to access it manually through the emulator. Are there any simple examples available? Hints? Best regards, Neil
