-------------- next part --------------
I ported u-boot to custom board and it works fine :)
but kernel hangs during initialization :(
It hangs in the function free_area_init_core() in the
following code:
for (i = 0; i < size; i++) {
struct page *page = mem_map + offset + 1;
....
}
function is called from:
start_kernel() - setup_arch() - paging_init() - free_area_init()
I made sure that:
a) IMMR_ADDR (Linux) = CFG_IMMR (u-boot) = 0x02000000
b) struct bd_info are the same in Linux an u-boot
c) CONFIGURE_CLOCKS_IN_MHZ is not defined - I have kernel 2.4.24
Do you have any idea what I can do? What is the problem?
I use ELDK 3.0. Kernel is from this distribution as well.
Configuration of my board for Linux is based on TQM8260
but my console is on SCC1.
Log of the session is as follows
