Hi,Experts:

     pdk :    pdk_jacinto_08_04_00_21

     I used SBL to load MCU1_0,  --> It could  run in  MCU1_0 main function,   

 But   I found It run to Os_Isr_Core0_UnhandledException_3 when I enable or suspend IRQ . I found the  Mcu_Timer0  had over flag interrupt . 

(I thought the Timer module didn't have IRQ handle function and The SBL init this....)

    I want to clear this IRQ ,but it no work, I saw the Top Url found the answer that  I need to disable the IRQ in source place , 

    So  , can tell  me how to comment the MCU_Timer0 module in SBL package?I don't find that....

    Or have some parameter setting in SBL?  I found the URL: 

In   rtos_linux_8.4\psdkra\pdk_jacinto_08_04_00_21\packages\ti\boot\sbl\sbl_component.mk      ,   And enable " SBL_SKIP_MCU_RESET "  But It not work.  
   
Thanks for your reply!

    Hi,

    Can you please elaborate on the use case here?
    Please confirm if the below understanding is correct about the issue you are facing:

    1) When you enable or suspend MCU_Timer0 IRQ, you see that the SBL Is running into exception.
    2) You are looking for a way to disable the MCU_Timer0 module in SBL

    Also, can you please share the changes that you have done due to which you are getting the above exception.

    Regards,

    Hi,Parth:

        Thanks for your replied,I finished this by using XDS560 to Debug & located the issue.

        MCU1_0 had this issue because of set value into MAIN Domain address. (this is other issue...)

    Best Regard!.
