Hello,
The memory of the MPC8572DS can't be read correctly after the setup of the tlb1_entry in the 4K boot code.
What specific memory location can't be read? What part of the code is failing?
What version of U-Boot are you running?
And also in the create_init_ram code, the tlb1_entry15&14 are set to be in the address space 0 which are supposed to be used in the address space 1. There seems somthing wrong with the writing of the TLB entry. But I don't know why. Do anyone know the reason?
If you mean create_init_ram_area in start.S, it is creating the entries in AS1. What do you see than indicates the contrary?
