Actually, it hangs changing gd pointer, before set_tlb() call. In my older u-boot version, it was made in cpu_init_f function.
/* Pointer is writable since we allocated a register for it */ gd = (gd_t *) (CONFIG_SYS_INIT_RAM_ADDR + CONFIG_SYS_GBL_DATA_OFFSET);

Hi,
I'm trying to update my u-boot version (1.2) to the last one (2009.03). My board is very similar to MPC8548CDS. Everything was working fine till I tried to use the reset command. It hangs the processor in cpu_init_early_f, when it realocates ccsbar. I'd always used the hard reset in DBCR0 register instead HRESET_REQ that ins't wired in my board.
I saw that the value of MSR register came different before reset when I compare with the old u-boot (0x8000 -> 0x29200). There are new writes in this register in this new version, could any of them causing my problem?
The major difference beetwen my configuration and default resides in u-boot.lds. I changed ADDR(.text) by the fisical init address of my boot flash, that is different of my TEXT_BASE, but bootpg and resetvec still in the same address, so I think that it couldn't be the problem.
u-boot.lds:
.bootpg 0xfff80000 + 0x7f000 :
< .bootpg ADDR(.text) + 0x7f000 : { cpu/mpc85xx/start.o (.bootpg) } :text = 0xffff
.resetvec 0xfff80000 + 0x7fffc :
< .resetvec ADDR(.text) + 0x7fffc : { *(.resetvec) } :text = 0xffff
. = 0xfff80000 + 0x80000;
< . = ADDR(.text) + 0x80000;
Thanks in advance, Werner Nedel.
