Dear community,

 

We have been developing our product with iMX257.
We plan to use Wait Mode for low power consumption.
We would like to monitor the Wait state .

 

In reference manual (IMX25RM Rev. 2) ,
it seems that the GPUSR1(A_WFI bit ) indicates the ARM core standby wfi.

 

We would like to access  the GPUSR1 registe with JTAG-ICE.

 

[Question]
        What kind of method can we access GPUSR1 by?

 

        We can not find the GPUSR1 register address .
        How many value is the $BASE ?

 

    Best Regards,
    Koichi Sakagami
