Hello Friends,

I am facing some problem in understanding the booting sequence of MPC8323E.

The MPC refernce manual says:- -- At PORESET, the processor loads RCW from Local Bus EEPROM or I2C EEPROM. After decoding the RCWH, it jumps to the boot code location found in it.--

The MPC8323E-RDB memory map is as follows:-

0x0000_0000 - 0x01FF_FFFF -- DDR

2GB -- PCI -- PCI

0xE000_0000 - 0xE01F_FFFF -- IMMR 0xFE00_0000 - 0xFEFF_FFFF -- Local Bus EEPROM(Flash 16 MB)

RCWH - A060_0000 RCWL - 4205_0083

My understanding is as follows:--

1. At PORESET, the processor loads RCW from Local Bus Flash. The address at that time is 0x0000_0000. 2. After reading the BMS and ROMLOC of RCWH, it locates to the address 0x0000_0100 and here it finds "uboot", the execution proceeds and the LBLAWBAR0 is programmed with 0xFE00_0000. thus Flash relocation occurs and then the kernel is uncompressed to DDR if allowed to boot.

If this is Ok, or there is some flaw in it..?

Thanks..
