Hi All,
Reloading the dspbridge several times I am getting a Segmentation fault. Seeing the log it seems that the memory was exhausted
The error happens when ioremap is called
void MEM_ExtPhysPoolInit(u32 poolPhysBase, u32 poolSize)
{
u32 poolVirtBase;
/* get the virtual address for the physical memory pool passed */
poolVirtBase = (u32)ioremap(poolPhysBase, poolSize);
.
Putting some printk's and printing the address returned by ioremap, I realized that address returned by ioremap each time I reload the dspbridge is different, in fact the address is increasing. I also put a printk where iounmap is called to make sure it is called and yes it is actually called. However testing with a kernel + bridge for linux 23x I always get the same address for pool memory. Any idea what the problem is? I have included the console output where you can see the address increasing.
Regards,
Fernando.
