Hi Pavel, I thank to you for your answer, but I've already read this page. As you can see from the log the machine number seen is 0x00000e05, which is the number of the TI AM335X-EVM, but in the list of available supported machine there are only: - ffffffff Generic DT based system - ffffffff Generic AM33XX (Flattened Device Tree) I think that the number 0x00000e05 is passed by boot to the kernel, but I cannot understand why I've only this two machine type. Where do they come from? I don't know where. I've searched on line and usually the problem comes from the DTB not loaded or something similar, but I cannot see anything wrong in what I've done. Could you please suggest something else? Best regards Roberto

Forum Post: Linux/AM3354: AM3354:timer7:Unable to configure timer7 as PWM using the user space script or Kernel module

I cannot figure out how you specify the ARM compiler path, options and the path to the target file system or sysroot. Should we create a CMAKE_TOOLCHAIN_FILE under /framework/delibs/cmake.

Ganesh, Taking a look at this, your U-Boot is very old, 2015.07, and you are using older Silicon, ES 1.0. Do you have the option to upgrade to a newer version of both, at least to check this problem?

[quote user="Tracy Smith6"] Tom any resolution to this issue? Was it a DDR issue or the device tree, or symbol problem and what did you do to resolve the problem? [/quote] Hi Tracy, It was a problem with the methodology of the wiki. Essentially the u-boot.bin that the wiki article at the original post mentions needs to be u-boot-dtb.bin. This may be because that wiki article was written before the device tree was added to U-Boot and Linux. For SPL I also used u-boot-spl-dtb.bin and had some success there too. I never did manage to get the Linux debug working, sadly. I also noticed while getting U-Boot and SPL running that I had an EMIF configuration issue, and once I modified that I was able to get to the U-Boot command line.

Forum Post: RE: Linux/AM5728: Linux Memory Policies
Hi Pavel, thanks for the reply. I've modified both of these memory@0 nodes to fit my config (256MB starting at 0x80000000): memory@0 { device_type = "memory"; reg = ; }; I've also modified the reserved-memory node as such: reserved-memory { /delete-node/ ipu2_cma@95800000; /delete-node/ dsp1_cma@99000000; /delete-node/ ipu1_cma@9d000000; /delete-node/ dsp2_cma@9f000000; cmem_block_mem_0: cmem_block_mem@a0000000 { reg = ; }; }; so that the DSP/IPU nodes are not used (they are disabled as well later in the DT) and the cmem block is moved to a space in RAM (and shrunk) that exists on my system. I've unfortunately had no results. This is the output I receive: Starting kernel ...

Tom, I tried different approach by using another KS2 platform, K2E, and different release, ProcSDk 4.0.0.4. I was able to mount and even create a file with size of 10M. However, when moving back to K2H with ProcSDk 4.0, I am still having issue using K2H and the setup isn't stable enough to test NFS over XGE. I'll check with MCSDK on K2E.and see how I can get the setup running. Rex
