Bootloader: Flash Download Failed

Lillian XU

HI All,

I compile the DFU example from ST using Keil MDK and try to download it into Bank 1. I always get a error: Flash Download failed -- ARM966E-S(I am using STR912FAW44). The following is what I do:

I setup the uVISION IDE the same as the thread http://www.keil.com/support/docs/3347.htm

Setup FMI in str91x.s


FMI_SETUP       EQU     1
FMI_CR_Val      EQU     0x00000018
FMI_BBSR_Val    EQU     0x00000000
FMI_BBADR_Val   EQU     0x00000000
FMI_NBBSR_Val   EQU     0x00000006
FMI_NBBADR_Val  EQU     0x00400000
FLASH_CFG_Val   EQU     0x00000000

Setup STR91xCFG.s


CFG             EQU     1
CFG_W0          EQU     0x00000000
CFG_W1          EQU     0x00010000

What am I missing in my project setting?

Thanks

Lillian

    Lillian,

    I made the changes and just tried compiling this here using MDK 4.14. I didn't get any warnings see below.

    
Build target 'STR91xFxx4 Bank1 ICP'
compiling FlashDev.c...
linking...
Program Size: Code=0 RO-data=4256 RW-data=4 ZI-data=0
User command #1: cmd.exe /C copy STR91xFxx4B1.axf ..\STR91xFxx4B1_.FLX
        1 file(s) copied.
"STR91xFxx4B1.axf" - 0 Error(s), 0 Warning(s).

    I have uploaded the file for you at

    www.filedropper.com/str91xfxx4b1

    So you can try this one if you want

    Regards,

    Stuart.

Could you please sene me the email lillian201151@hotmail.com so I can send you my design file?

    Hi,

    I find the reason to fail program.
    Go to Options for Target -> Debug -> Ulink ARM Debugger Settings -> MAX JTAG Clock

    Change MAX JTAG Clock from 1M to 500K.

    Then flash program will be successful.

    Best Regards,

    Lillian
