we are plan to use 256MB address for flash from 0xF0000000 to 0xFFFFFFFF, so we tried to relocate the CCSRBAR address from 0xFE000000 to 0xEE000000. (Verified 0xEE000000 - 0xEEFFFFFF is address range is not overlapped)


CCSRBAR update Sequence are verified as per Reference manual section Updating CCSRBARs.


I used the default CCSRBAR address, system is booting fine from bootrom.If I changed CCSRBAR address from 0xFE000000 to 0xEE000000 board not booting. During debug with code warrior system connection lost after commit bit (C).


1) All reference board are using the default CCSRBAR, whether it is possible to change the CCSRBAR address?


2) Any other reference/errata available to change CCSRBAR address?
