About DFU(Device Firmware Update) for LINUXEZSDK-AM335X V07.00

Hi

In the following URLs(Texas Instruments Wiki), there are the steps of using the dfu command in uboot.

1.AM335x USB Device Firmware Upgrade User Guide
http://processors.wiki.ti.com/index.php/AM335x_USB_Device_Firmware_Upgrade_User_Guide

2.Linux Core U-Boot User's Guide
http://processors.wiki.ti.com/index.php/Linux_Core_U-Boot_User's_Guide

In EZSDK V06.00, I have ran the dfu with no problems, but it did not work correctly with EZSDK V07.00.

I paste the detail at below.

----------------------------------

like the detail at above, I got the error messge "dfu_get_buf: Could not memalign 0x800000 bytes" in EZSDK V07.00(u-boot-2013.10-ti2013.12.01).

Is this a bug of u-boot-2013.10-ti2013.12.01? How can I use dfu command in u-boot-2013.10-ti2013.12.01?

 

Thanks!

    Hi,

    This may be related to the value of CONFIG_SYS_DFU_DATA_BUF_SIZE (8MB by default). This is also the DFU_MAX_FILE_SIZE which is equal to the DFU_DATA_BUF_SIZE. Try to change these. Here is what the U-Boot readme says about these two:

            CONFIG_SYS_DFU_DATA_BUF_SIZE
            Dfu transfer uses a buffer before writing data to the
            raw storage device. Make the size (in bytes) of this buffer
            configurable. The size of this buffer is also configurable
            through the "dfu_bufsiz" environment variable.

            CONFIG_SYS_DFU_MAX_FILE_SIZE
            When updating files rather than the raw storage device,
            we use a static buffer to copy the file into and then write
            the buffer once we've been given the whole file.  Define
            this to the maximum filesize (in bytes) for the buffer.
            Default is 4 MiB if undefined.

    If my suggestion doesn't help, please direct your question to the U-Boot mailing list.

    P.S.

    Which version is your dfu-util package?

    Best regards,
    Miroslav

    Hi Miroslav 

    Thanks for your reply.

    When I ran dfu-util -l, the output is 

    dfu-util 0.5

    So I think the version of dfu-util is 0.5.

    I will try to change the  "dfu_bufsiz" environment variable.

    Thanks!
