Burning Cortex-M3 of ST with ULINK2

Eli L.

Dear All,

I work on STM32F101V8 uC. I'm faced with a strange phenomenon related with burning. Once I downloaded a new firmware version to Flash and then started the program running by starting Debug Session in the uVision IDE, the program will continue to run if I close the Debug session or even if I physically disconnect the JTAG cable from my board. But if I want the program to start independently after the burning without JTAG's help, it does not work ! I tried to burn the firmware with J-FLASH of Segger as well, but the I have received the same result.

Can anybody explain me, please, what's going on here ?

Thanks in advance,
Eli.

    Hi,

    I think everything is OK with the start address. If I go to Options->Target,at the IROM1 Start address I see 0x8000000, which is the correct Flash start address.
    Regarding the Reset Vector, if assume there is a wrong address of main(), the software would not work even with JTAG interface too. Or perhaps, I didn't understand what did You mean ?

    Thank you very much,
    Eli.
