Hi team,
Currently, in my customer's system the following registers are restricted in PCIe RC mode.
・NUM_bits(*1) of PCIe_core_ATU_wrapper_OB_I_addr0 Register
・Region_size(*1) of the PCIe_core_ATU_wrapper_OB_I_AXI_addr0 Register
(*1) Refer to J721E_registers4.PDF
When they checked the operation of the above field setting, it was only effective up to 16MB (NUM_bits = region_size = 0x18).
1. Is it possible to operate with a specified size of 16MB or more?
2. If the above (1) is possible, please tell us which register to check or set.
Thank you in advance.
Best Regards,
Kenley
