Bootloader: Flash Download Failed

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

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
