WINCE ARM A8 01 01 00 DEMO and BSP does not boot on DM3730 EVM

This worked on BSP_WINCE_ARM_A8-1.00.00.14, I upgraded to the latest and now broke:

The demo images and latest BSP compiled do not boot from SDCARD on DM3730 :

    Hi Mark,

    Are you not seeing the LCD display upon boot up?

    Could you enable retail messages from main menu (Enable/Disable OAL Retail Messages option) and see if any errors are being printed? As such, the console messages do not indicate any failure to boot up.

    Thanks,

    Aparna

    Hi,

    I see the logo form eboot on the EVM display.

     

    With retail messages on:

     

    Selection: 0

    Init HW: controller RST

    Mark,

    (a) You are using an older rev of 3730 (1.0) which is not supported by this BSP.

    (b) Since its an older rev of 3730, looks like the Smartreflex data is not burnt in. Can you try the following change in EVM_OMAP3530\SRC\OAL\OALLIB\opp_map.c :

     

    static unsigned int SmartReflex_Adjust_EFUSE_nvalue(unsigned int opp_no,

                                                                            unsigned int orig_opp_nvalue,

                                                                            unsigned int mv_delta)

    {

                If (orig_opp_nvalue != 0)

    {

                unsigned int new_opp_nvalue;

                unsigned int senp_gain, senn_gain, rnsenp, rnsenn, pnt_delta, nnt_delta;

                unsigned int new_senn, new_senp, senn, senp;

     

                UNREFERENCED_PARAMETER(opp_no);         

     

                /* calculate SenN and SenP from the efuse value */

                senp_gain = ((orig_opp_nvalue >> 20) & 0xf);

                senn_gain = ((orig_opp_nvalue >> 16) & 0xf);

                rnsenp = ((orig_opp_nvalue >> 8) & 0xff);

                rnsenn = (orig_opp_nvalue & 0xff);

     

                senp = ((1<<(senp_gain+8))/(rnsenp));

                senn = ((1<<(senn_gain+8))/(rnsenn));

     

                /* calculate the voltage delta */

                pnt_delta = (26 * mv_delta)/10;

                nnt_delta = (3 * mv_delta);

     

                /* now lets add the voltage delta to the sensor values */

                new_senn = senn + nnt_delta;

                new_senp = senp + pnt_delta;

     

                new_opp_nvalue = cal_test_nvalue(new_senn, new_senp);

     

                OALMSG( TRUE, (L"Compensating OPP%d for %dmV Orig nvalue:0x%x New nvalue:0x%x \r\n",

                                        opp_no, mv_delta, orig_opp_nvalue, new_opp_nvalue));

                }

     

                return new_opp_nvalue;

    }

    if this doesn't fix the crash, then please look at nk.map and see what the exception PC address points to?

    Modifying opp_map.c solved the problem.

    Thanks!
