  • Forum Post: Loading U-Boot

    SJackson
    I am using Code Composer Studio and a Blackhawk JTAG pod to burn U-Boot to Flash memory on my DaVinci-based board. I'm using the flash writer CCS application supplied by TI for programming the EVM, modified to recognize the Flash chip/manufacturer that I'm using. Furthermore, I have modified...

  • Forum Post: Re: A question when Booting via TFTP

    Bernie Thompson TI
    This is a strange one, but is not out of the question, a DHCP server has the ability to define a file, and it is likely that your particular router defines this with that square character, thus breaking the TFTP boot sequence. I am curious if your board ever was able to boot from TFTP? If it was able...

  • Forum Post: Re: about MLC nand support

    Juan Gonzales
    Please note that if you are using a NAND part different than what is used on our EVM, it may require you add NAND support for your particular NAND device; u-boot is open source software and the number of NAND parts it supports has increased over time, but it does not guarantee support for all MLC NAND...

    The DM355 serial loader is available now, the Wiki page here shows instructions, and you can download it from sourceforge here .

  • Forum Post: How can I reflash u-boot to NAND flash on DM355 without CCS/JTAG?

    Juan Gonzales
    You can either 1) use u-boot itself to program NAND flash (see Getting Started Guide for details), or 2) Use a serial port utility available at the following link http://wiki.davincidsp.com/index.php?title=Serial_Boot_and_Flash_Loading_Utility

    This is a very good point. I believe there is a u-boot patch that will allow u-boot to work with GBit Ethernet.

    Bernie Thompson TI
    To look into this further could you post your U-Boot arguments? I am also curious if this is on a custom board or on the DM355 EVM? It seems quite strange that it attempts to load uImage and than goes into the UBL and back into U-Boot, it is as if the attempt to load the uImage is causing the device...

    Bernie Thompson TI
    It looks like the DM355 serial loader does not include the U-Boot binary, this being the case you just have to get the U-Boot binary from your DVSDK installation, in particular you should be able to find a U-Boot binary within dvsdk_1_30_00_40\PSP_01_20_00_014\bin\dm355 or similar.

    hi juan, is there a nice guide on how to upgrade the target 6446? my u-boot version is "U-Boot 1.1.3 (Dec 4 2006 - 12:05:38)" and i was thinking it would be great if i can upgrade the whole package. the main reason is because i was going to use gstreamer for a class project and gstreamer...

  • Forum Post: Re: Bad Magic Number

    Bernie Thompson TI
    Bad magic number means that when U-Boot tried to boot the UImage kernel image it found that the kernel image was not valid, i.e. the magic number it expected at the beginning of the image was not there or otherwise corrupted. This normally means that your UImage is missing or your UImage is corrupted...

  • Forum Post: Re: Bad Magic Number

    Bernie Thompson TI
    Could you post your U-Boot arguments from 'printenv' as well as a log of the output from your failed boot? I would guess that something is wrong in there such that you are not TFTPing the proper file or that the TFTP is failing, either way we should be able to give you some further insight if...

  • Forum Post: Re: Bad Magic Number

    Bernie Thompson TI
    Try running 'boot' instead of bootm, bootm will try to execute an image in DDR that may not exist yet, particularly if you did not run 'dhcp' yet. This is why your bootcmd is set to dhcp;bootm, so when your board boots it runs dhcp to load the uImage and than executes it with bootm. ...

    Juan and Bernie, FYI, it was not damaged hardware. There was a bug in one of our OSD drawing routines that only appeared after we changed the bootargs to the NTSC dimensions. Anyway, we still do not understand those kernel errors, but at least we are running, again (for now)... Thanks, much,...

  • Forum Post: Re: JTAG Code Updating on DM355

    Bernie Thompson TI
    I would suggest using the serial flash loader, typically you would only use the serial flash loader to get the initial boot loader (UBL and U-Boot) on to the board, and than you would burn your uImage and filesystem utilizing U-Boot. Once you have U-Boot on the board using the serial flash loader there...

    Bernie Thompson TI
    Naveed Alam Do I need U-Boot as well to start a Linux kernel? Yes, U-Boot is the actual kernel loader, the UBL is just a loader for U-Boot. UBL is necessary because U-Boot itself is typically too large to fit in the internal memory that would be available when the board first boots, so UBL which will...

    Bernie, thank you for your reply, but this is not the area that I am concerned with. Under MVL v4 the bootargs for setting up the framebuffer worked without a problem. They were setenv bootargs 'video=davincifb:vid0=720x576x16,2500K:vid1=720x576x16,2500K:osd0=720x576x16,2025K davinci_enc_mngr...
