Problem connection to Prototyping board

Other Parts Discussed in Thread: TMS570LS20216, HALCOGEN

Hi,

I am trying to connect and load my program but everytime i get the following error

"Error connecting to the target:

(Error -2062 @ 0x0)

Unable to halt device. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK).

(Release 5.0.333.0)"

In my board i see the ESM pin gets set  everytime i reset the board with POR reset
maybe someone can give me an advise how can i establish a connection to the board?
Regards
Burim

    1. Check if the Oscillator/Crystal has signal, if it has 16MHz signal

    2. Try to erase the flash using nowFlash, it can be download from: http://focus.ti.com/mcu/docs/mcuprodtoolsw.tsp?sectionId=95&tabId=2661&familyId=1870&toolTypeId=1.

    Hi Haixiao

    1. For the first proposal i dont have an oscilloscope  to perform the check

    2. With nowFlash it is the same: can't connect to the board.

    This problem happens since i installed the HalcoGen 2.09 Today

    Actually in my system.c i have seen this changes

    ---------------------------------------------------------------------

        /** @b Initialize @b Lpo: */<

        systemREG1->LPOMONCTL = (0U << 24U)

                              | (8U << 8U)

                              |  8U;

        /** @b Initialize @b Secondary Pll: */

        systemREG2->PLLCTL3 = ((2U - 1U) << 22U)

                            | ((10U - 1U) << 8U)

                            |  (1U - 1U);

    ------------------------------------------------------------------------

        /** - set ECLK pins functional mode */

        systemREG1->SYSPC1 = 0U;

     

        /** - set ECLK pins default output value */

        systemREG1->SYSPC4 = 0U;

     

        /** - set ECLK pins output direction */

        systemREG1->SYSPC2 = 1U;

     

        /** - set ECLK pins open drain enable */

        systemREG1->SYSPC7 = 0U;

     

        /** - set ECLK pins pullup/pulldown enable */

        systemREG1->SYSPC8 = 0U;

     

        /** - set ECLK pins pullup/pulldown select */

        systemREG1->SYSPC9 = 1U;

     

        /** - Setup ECLK */

        systemREG1->ECPCNTL = (0U << 24U)

                            | (0U << 23U)

                            | ((8U - 1U) & 0xFFFFU);

    --------------------------------------------------------------------------------

    I has checked my Application without these upper Code lines in another  board  and it runs fine

    Will try to analyze this lines to see what happens

    Regards

    Hi

    After several many trying the solution was to hold pressed the warm reset button

    and flash the new code in the microcontroller
