Dear Simon
I just wanted to play around with the sandbox "arch" of u-boot maybe adding tun/tap support. Current head compiled successfully but crashed immediately after startup in board_init_f:
gd = malloc(sizeof(gd_t)); assert(gd); memset((void *)gd, 0, sizeof(gd_t));
The simple reason was that malloc refers to u-boots internal malloc which is not initialized at this point. I added the following snippet
That is odd. This commit is supposed to switch over to the system malloc():
fe34107 sandbox: Disable built-in malloc
Can you please check that it is there?
This commit is there. But it seems to be ignored. dlmalloc.c is build and linked on my machine here.
I would first check that dlmalloc.o is not being linked, and that mem_malloc_init() is undefined.
The current setup works OK for me, but yes it would be nice use U-Boot's internal malloc(). The initial effort was to get a baseline implementation into U-Boot and there are a number of areas where it can be expanded. We want to test as much as possible of the code, and dlmalloc is no exception.
Please see http://patchwork.ozlabs.org/patch/123074/ I just posted. This may be a solution for this issue and we can use dlmalloc in sandbox.
