  • 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

    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.

  • 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...

  • Forum Post: Re: UBL or U-Boot

    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...

    I set the env variables to do a tftp boot with a nand filesystem. When I booted I got a bunch of 'Too many NAND ECC errors' messages. I'm reluctant to try the boot from FLASH method since I clobbered the board and we had to restore the FLASH using a JTAG/Code composer setup. Can someone confirm...

    Wei Jiang, If you want to be able to flash ubl from u-boot or when running the linux kernel, you will have to match the ecc positions assumed by RBL. You will have to make these changes in both u-boot and the kernel since neither of them match the RBL implementation. Most people don't flash ubl...
