The heap area is not being setup properly. It appears that all of the ARM boards cpu.c and start.S were from the same root. In cpu.c _armboot_real_end is set up such that the malloc init in lib_arm/board.c's should work... It appears that the pxa's start.S diverged from the way the other ARMs did the relocation and ended up breaking this aspect of the init.

So, the PXA and could change to be like the other ARM boards or ... I recall that part of a patch to board.c someone posted should result in this working for PXA. Having malloc work is important beyond getting the device_init structure up and running. Either should fairly straight forward to do.

I recently updated from u-boot 0.3.2 to CVS (0.4.5). Now blob stopped working. I tracked this down from device_init() to ListCreate() or NewHandle().

My debug output is:

U-Boot 0.4.5 (Aug 15 2003 - 18:26:38)

U-Boot code: A3000000 -> A300D4E0 BSS: -> A3024000 DRAM Configuration: Bank #0: a0000000 128 MB Flash: 32 MB 1 2 4 6 7 9 10 d1 d3 l1 n1 n2 memPtr=0badc0e8 n3 hanPtr=0badc108 n4 l2 l3 0badc108

list_t ListCreate (int elementSize) { list_t list; printf("l1\n"); list = (list_t) (NewHandle (sizeof (ListStruct))); /* create empty list */ printf("l2\n"); if (list) { printf("l3 %08x\n", list); (*list)->signature = LIST_SIGNATURE; (*list)->numItems = 0; (*list)->listSize = 0; (*list)->itemSize = elementSize; (*list)->percentIncrease = kDefaultAllocationPercentIncrease; (*list)->minNumItemsIncrease = kDefaultAllocationminNumItemsIncrease; } printf("l4\n");

    return list;

}

Target is an Intel PXA255
