Dear u-boot-users,
u-boot works on my custom board (MPC875, 64MB RAM, 16MB flash) but linux hangs (see debug console output below) when started with bootm-command.
I am using the ELDK 3.1.1 kernel sources (version 2.4.25) and a u-boot CVS version which is slightly newer than the 1.1.3 release. CLOCKS_IN_MHZ is not defined in my u-boot board config file and the IMMR define is in kernel and u-boot board config file identical.
I noticed, that bd_info structure in u-boot/asm-ppc/u-boot.h and eldk/ppc_8xx/ usr/src/linux/include/asm-ppc/ppcboot.h differ abit: in the kernel sources a
mon_fnc_t *bi_mon_fnc; /* Pointer to monitor functions */ } bd_t;
pointer to monitor funcs is defined, which is does not appear in u-boot.h. Is this intended or a bug ?
What else could i tryout before analyzing kernel log buffer and debugging the kernel ?
best regards,
Josef
