I have a specific problem in 405gp on embeddedplanet board.
it is gets hanged in MEMCPY() below.
void __init
Board_init(unsigned long r3, unsigned long r4, unsigned
long r5,unsigned long r6, unsigned long r7)
{
/*
* If we were passed in a board information, copy it into
the
* residual data area.
*/
if (r3) {
memcpy((void *)__res, (void *)(r3 +KERNELBASE),
sizeof(bd_t));
}
i am using board reset ( bl reset) type of macro for debugging for
detemining the hang .
if i put bl reset macro before memcpy the board gets reset but
not after the memcpy .
abort being ..._GLOBAL(abort)
mfspr r13,SPRN_DBCR
oris r13,r13,DBCR_RST(DBCR_RST_SYSTEM)@h
mtspr SPRN_DBCR,r13
can anybody help me with any pointer....

Looks like you are using an older kernel (2.4.2 ish). You should pull
from the latest devel. I have used the ep405 as have a few others.
