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.
Regards.
Motu.
Mentioned evaluation board have connected DDR SDRAM on these pins, there is no memory accessible by EBI module on this EVB.
EBI/DRAM pins are shared thus it is not surprising you cannot read anything from this memory.
