Hi all .

        i have a custom board of P1020 which i want read CCSRBAR value after the board power up by JTAG. The e500 core have only 4K tlb memory map valid after reset , the CCSRBAR 1M memory don't have default TLB to map it . I find no TLB correspond to CCSRBAR memory have been set up before JTAG access the memory region .  The AN3366 "Simplifying Board Bringup" pdf show how to set up Initialization file for JTAG ,  i can't find any step to create TLB before access CCSRBAR region.  Is there no need set TLB for CCSRBAR region ?  can someone give me some suggestion ?

 

thank you
