Fail to sign application image

[longxing]

Hi,

    I want to sign my image using elftosb.exe,but it only show following information,and there is no file named bootloader_signed.bin generated.

> .\elftosb.exe -f imx -V -c imx-sdram-bootloader-signed.bd -o bootloader_signed.bin evkbimxrt1050_flashloader.axf
        Section: 0x14
        Section: 0x15
        Section: 0x16
        Section: 0x18
        Section: 0x19
        Section: 0x1a

     I changed evkbimxrt1050_flashloader.axf to evkbimxrt1050_flashloader.bin,the .bin file was generated by utility provided by MCUXpresso IDE. I got following message:

> .\elftosb.exe -f imx -V -c imx-sdram-bootloader-signed.bd -o bootloader_signed.bin evkbimxrt1050_flashloader.bin
        Section: 0x14
        Section: 0x15
        Section: 0x16
        Section: 0x18
        Section: 0x19
        Section: 0x1a
Install SRK
Install CSFK
Authenticate CSF
Install key
Authenticate data
Invalid Block arguments, Blocks start offset and length together exceed file size in command AuthenticateData
error: failed to run code signing tool

 it sems that the signing process stoped at Authenticate data phase.Checking the input.csf generated by elftosb，I found the following statements:

[Authenticate Data]
    Verification Index = 2
    Engine = DCP
    Engine Configuration = 0
    Blocks = 0x60001000 0x1000 0x20 "temp.bin",\
             0x60001020 0x1020 0x20 "temp.bin",\
             0x60001040 0x1040 0x420 "temp.bin",\
             0x6e6f 0xa0006e6f 0x20990 "temp.bin"

 I don't know from where the address 0x6e6f and offset 0xa0006e6f in the last line of input.csf come.

 I guess there must be some wrong settings in my customed evkbimxrt1050_flashloader project,but I don't know how and where to modify.

Any suggestion is appreciated .

Best regards.

ps:my evkbimxrt1050_flashloader project can run on RT1052 normally.The axf and BD file i used are attached
