According to the e5500 core reference manual, there is a TLB1 entry present after reset. It also states that the upper 6 bits of the Real Page Number (RPN) are applied to the core by SoC. However, I couldn't find specific details about these 6 bits in T1040 reference manual. Could you clarify what these 6-bit values are for T1040 SoC? This information might be helpful to add to T1040 SoC documentation if it is missing.

Thank you.

The default RPN[28-51] in TLB1 entry0 after reset is fffff. So RPN[28-33] is "000011".

@yipingwang thanks for the information, but could you please refer to where you found it in the reference manual? because I also knew it should be '00011" but it is not stated in the reference manual. please refer to the section in the reference manual.

Why this information is not available in t1040 reference manual. This info can be added to the manual for its next revision.

Thanks.
