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 had to change the FLASH programming options for programming bank 1 on our STR9 systems.

    You change these by opening a Keil project under
    Keil\ARM\Flash\STR91X

    You then have to select the target STR9 derivative, bank and programming type from the project options

    Then in the file FlashDev.c you will see one of these for each STR9 derivative, bank and programming type, this is for STR91xFxx7, Bank 1 and ICP programming

    
#ifdef STR91xFxx7
struct FlashDevice const FlashDevice  =  {
   FLASH_DRV_VERS,             // Driver Version, do not modify!
   "STR91xFxx7 Flash Bank1 ICP",  // Device Name
   ONCHIP,                     // Device Type
   0x00400000,                 // Device Start Address
   0x00020000,                 // Device Size in Bytes (128kB)
   0x00004000,                 // Programming Page Size
   1,                          // Reserved, must be 1
   0xFF,                       // Initial Content of Erased Memory
   6000,                       // Program Page Timeout 6000 mSec
   3000,                       // Erase Sector Timeout 3000 mSec

// Specify Size and Address of Sectors
   0x004000, 0x000000,         // Sector Size 16kB (8 Sectors)
   SECTOR_END
};
#endif

    I increased the time-outs for bank 1 to these (I think I just copied the Bank 0 options)

       6000,                       // Program Page Timeout 6000 mSec
   3000,                       // Erase Sector Timeout 3000 mSec

    from these values

    
   100,                        // Program Page Timeout 100 mSec
   1000,                       // Erase Sector Timeout 1000 mSec

    You then rebuild the project, and try programming bank 1 again in the normal way.

    Hope this helps.

    Stuart.

    Hi Stuart,

    Thank you very much for your help. I try to change the timeout value for STR912FAW44. It can 2 times successfully download in 10 times try. I wonder if you can 100% download successfully.

    Thanks again for your help.

    Lillian,

    I use a STR9FAZ47 and we can program ours 100% of the time.

    I use the ICP method for programming, as I also programming the STR9 configuration registers.

    Hi Stuart,

    When I compile the STR91x flash file using keil MDK, i got the three warning message.


    Build target 'STR91xFxx4 Bank1 ICP'
    compiling FlashDev.c...
    linking...
    STR91xFxx4B1.axf: Warning: L6305W: Image does not have an entry point. (Not specified or not set due to multiple choices.)
    .\TargetX.lin(12): warning: L6314W: No section matches pattern *(RW).
    .\TargetX.lin(12): warning: L6314W: No section matches pattern *(ZI).

    "STR91xFxx4B1.axf" - 0 Error(s), 3 Warning(s).

    I wonder if the warning message affect the downloading.

    Thanks

    Lillian,

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

compiling FlashDev.c...
linking...
Program Size: Code=0 RO-data=4256 RW-data=4 ZI-data=0

    I have uploaded the file for you at

    www.filedropper.com/str91xfxx4b1

    So you can try this one if you want

    Regards,

    Stuart.

    Hi Stuart,

    Thank you for your kind help. I try your file and still get the programming failed. I check the chip version in my MCBSTR9 board is G. Also, could you please do me a favour to take a look at my STR91x flash file and see why i get the warning message. I find it cannot attatch file here. Could you please sene me the email lillian201151@hotmail.com so I can send you my design file?

    Thanks a lot

    Lillian

    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
