AM335X SERIAL FLASHER TOOL

Hi,

I'd like to ask where I can find the TI Serial Flasher tool to load a booting image into NAND Flash when forcing the processor to boot from UART0.

Thanks,

E

    E,

    Thanks for the post. For AM335x, we use UBOOT to do this. You can find some documentation here.

    Hope this helps,

    Ron

    Hi Ron,

    Thanks for your reply. I realize that my question wasn't worded clearly. I have worked with the DaVINCI family before and am familiar how to use uBoot to load an image into NAND.

    What I'm looking for is the TI tool that takes the UBL and uBoot binaries and loads them into NAND.

    If I remember correctly, the executable is called sfh_<processorname>.exe. Once the binaries of UBL and uBoot are created, this tool provided an easy way for flashing NAND since it had already built in means to ID the NAND memory.

    The process is to force the MCU to boot form UART0, then run the serial flasher executable calling the binary files to be loaded into Flash.

    I have also used CCS via the JTAG port to perform this task, however, if the hardware is connected properly, using the serial flasher tool is a lot less troublesome.

    Thanks,

    E

    Understand that this is the method that you have used for the other products, such as in the DaVinci family, primarily based on the collateral that TI had provided for those platforms.

    As Ron had mentioned, currently with the AM335x platform, this method is supported via U-Boot.  The link Ron provided is the direct path.  In addition to this, additional collateral is available via the following portal.

    There is also information on CCS based flashing on this portal under the Linux section.
