    Hi I am trying to use AN2475 for programming in the secondary flash booloader. I am using RLINK and IAR Kit ( ST makes it ).

    So far no success. Does anybody has CAPS project that does that flashing.

    Thank you in

    Advance

    It took me a while to get it to work

    When you compile the project on IAR select the ''debug-intel-extended'' output format which will produce the .a79 (aka intel hex) file.

    In CAPS, do the following on a new project:

    Additional Settings -> BootFlash = Secondary Flash

    -> Firmware Placement -> file start = 0x0000

    -> file stop = 0x3FFF

    -> file name = C:\IAP\project\EWARM\Debug\Exe\STR91x_IAP.a79

    Click the ''Apply'' button, then go to the next page.

    Program Device -> Step 1: make sure the *.obj file that was just created

    is selected

    Step 2: Select region: ''2nd Flash'' and ''Configuration''

    Select operation: Program/Verify

    Then click ''Execute''

    hope this helps,

    -Mark

    Thanks Mark,

    I did pretty much the same and still when I try to program it

    dive me this message

    Successful translation and merging...

    Device 1 : ( 4 pins )

    Device is secured. Select all regions for erase operation.

    Time elapsed : 1 sec.

    I am able to erase it but not to programmed ??

    Do you know anything about that ?

    What happens when you select all the regions (step 2 of ''Program Device'')?

    It sounds like you need to do a full JTAG erase of the entire chip to recover from the secure mode. I do not know what CAPS does if you select all regions and then ''Erase'' as the operation. I know that when I used Keil's uLink JTAG adapter, I was able to do a complete JTAG erase of the chip for a different problem. Maybe you should use the Raisonance tool to do a full chip erase.

    I have not had this problem.
