Hi,

#define LoaderAdd 0x00

unsigned int * tmp_pointer ;

unsigned char temp_data;

1. tmp_pointer = (unsigned int* ) (((unsigned long)LoaderAdd +0x100+i_cnt+n_cnt));
2. temp_data = (unsigned char) *tmp_pointer;

I get exception fault on line 2.:

A non-recoverable error or exception has occurred.
Description: A data CPLB miss has occurred without a corresponding CPLB entry.
General Type: RunTimeError
Specific Type: DCPLBMissWithoutReplacement
Error PC: 0x11a01a5c

Anyone knows, how I can fix the issue?

using BF706, CCES 2.3.0

The SEQSTAT_EXCAUSE is 0x26, which is used MMU to signal CPLB miss.

How can I fix it?
