I am using P5040DS-PB demo board. I need to access the boot flash (NOR flash 128MB) using the JTAG tool. What are the registers that need to be configured for proper board initialization , so that using the JTAG tool I can access the boot flash(NOR flash). I have verified the following register configuration - CCSRBAR, TLB, LAW, CS, Flash Part No. and Sector size but no luck.
