Hi,I am using MPC5675K EVB for testing EBI module. I can get the signals of CS0, BE, TS and OE, but can not read any corrent data(just 0xFFFFFFFF).

I probed the data/address bus signals and found none valid data. I did not try write operation.

The register configuration that I did is given below:

MCR: 0x00000803

BR0: 0x200008a3

OR0: 0xfffe0030

/* control signals */

PCR[147..154,156] = 0x081f;

/* data/address signals */

PCR[158..197] = 0x080f;


longword0 = *(vuint32_t*)(0x20000000);


I really appreciate any help and suggestion in advance.
