  • [SOLVED] J-link and AT91SAM7S256: Failed to download application - How configure new project?

    Hi

    I'm trying to write flash in AT91SAM7S256 target using J-link and Embedded Studio. When i has used default configuration I have result as bellow - it always fails for different reasons.
    I tested device using testwspeed command in J-Link Commander and i can write succesfully data into SRAM space but not into flash.
    But when I configured target using "w4" command (disable watchdog and change MCK to 10MHz from PLL), Flash has been also succesfully written.
    I also tried to connect with target using J-Flash and it also works - It can reset, halt and write default registers.

    My question: when in my projet (in Embedded Studio) i can add this actions (write some registers) to run it before writting into flash? Is .jlinkscript file correct place to do this?
    Unfortunatly i can't found any documentation describing this script.

    Edit:

    Now I'm confused. I see that if I every time execute power sequence (power off, power on, reset), then I can always succesfully run testwspeed on flash memory, but erase and loadfile never run without errors. (hex file I got from Embedded Studio). Due to problem with erase command I'm not now sure that is problem with configuration in Studio. Another question why addres 0x00200000 is used - it is a SRAM space, not flash in this target.

  • Hi,

    Target initialization can be done with a JavaScript file.
    In the project properties -> Target Script Options set the Target Script file to your JavaScript
    and set the Connect Script to the initialization function in your script.
    For more information about the script, refer to studio.segger.com/arm_target_script_TargetInterface.htm

    Best regards

  • Hi

    Thank you for reply. I tried to run additional scripts on connection but it also fails. Now I think that my problem is not with Embedded studio but with my board or target - so firstly I must investigate it or try another one.

  • Hi

    I has checked my target and it works, i found way to successfully write flash, and run program but only in J-Link commander - to write flash I must change target clock to higher - as on init sequence in J-Flash. I tried to add this sequence in Connect Script using TargetInterface.pokeUint32(address, data) and TargetInterface.delay(ms), but problem is earlier - write into memory fails due to unable to halt CPU. In J-Link commander i see that in this case only power sequence (power off, power on) works, and target is halted after reset. Is possible to add power sequence before reset in Embedded Studio?. Now target is always powered - also after disconnect. In J-Flash power is off after disconnect so during connection device is halted after reset.
    Another question - has been Embedded Studio tested with AT91SAM7S* target?

  • Hi.

    I think that I has found solution for my problem. AT91SAM7S has inactive reset pin for default, so is impossible to trigger user reset. To trigger software reset CPU must be halted - it is triggered by writing data into register. In conclusion only power on reset can reset CPU. I added enabling user reset (reset pin) after power on reset and now all works fine.
    My configuration

    Source Code

    1. TargetInterface.pokeUint32(0xFFFFFD08, 0xA5000001)
    2. TargetInterface.pokeUint32(0xFFFFFD44, 0x00008000)
    3. TargetInterface.pokeUint32(0xFFFFFF60, 0x00320300)
    4. TargetInterface.pokeUint32(0xFFFFFC20, 0x00000601)
    5. TargetInterface.delay(200)
    6. TargetInterface.pokeUint32(0xFFFFFC2C, 0x00191C05)
    7. TargetInterface.delay(200)
    8. TargetInterface.pokeUint32(0xFFFFFC30, 0x00000007)


    In first line user reset is enabled, next lines trigger disable watchdog, change flash states and change clock to PLL. It need external crystal to be connected.

    Than you for help.

  • Hi,

    Good to read you were able to solve the problem.
    Enabling reset and disabling the watchdog is always a good way to go.
