What's going on with shoot malloc?

[1%]

Initially shoot_malloc seemed to work fine.

I had an error in the card test and I fixed it like this:

    if (bufsize > 1024*1024) bmp_printf(FONT_MED, x, y += font_med.height, "read test skipped: buffer=%d\n", bufsize);
    else
    {
        //void* buf = alloc_dma_memory(bufsize);
void* buf = shoot_malloc(bufsize);
       


Worked fine for a while... I did r/w tests on my cards. Today I got a new UHS card:




Someone else is complaining about formatting also throwing a shoot malloc error.

"estart your camera (shoot_malloc err)." :R

But shoot_malloc passes the stubs test and it seemed to work not too long ago.

       m11 = MALLOC_FREE_MEMORY => 0x6f640
       m12 = GetFreeMemForAllocateMemory() => 0x2f4e0c


Only fails on date... which doesn't seem related.

After taking photos, the shooting memory becomes fragmented. I don't know how to handle these fragments, so it may fail to allocate large chunks.

Restarting the camera fixes this, at least for me.
