Hi All,


I am trying the DDR initialization now on T4160RDB-64 Machine by using Codewarrior Flashprogrammer and Lauterbach Trace32 Script. DDR initialization done successfully with following means when i check DDR_ERR_DETECT it is showing Automatic Calibration Error(ACE) bit set.



Is it issue ?


MMU Setup done for Flash and DDR. When access DDR (0x000) Memory the target reset.


In Lauterbach Script

;MMU Setup
;FLASH 0xe8000000--0xefffffff (1GB)
MMU.TLB1.Set 0. 0xC0000A00 0xe8000008 0xe8000015 0x00000000 0x00000000
