Hello Everybody,
I'm developing a project that uses a MPC885 processor, that has a embedded security processor. The MPC885 Reference Manual (http://www.freescale.com/files/32bit/doc/ref_manual/MPC885RM.pdf - Section 10.4.1) and a Application Note (http://www.freescale.com/files/32bit/doc/app_note/AN2800.pdf) say that bits D14-D15 of the IMMR register should be set to '10' to enable the access of the security processor (SEC Lite) registers. I tried to change my define CFG_IMMR from 0xFF000000 to 0xFF020000, but as result the U-boot hanged.
I searched the source codes of another boards (NETVIA, NETTAx) that also use the MPC885 but all of them set the IMMR to 0xFF000000.
So, I ask: someone here uses the Security Processor of MPC885? How to set the IMMR register to achieve the access of the SEC Lite registers??
Thanks in advance and Best Regards,
Bruno
