Hi, I'm working with RTEMS for LPC1768. I need know how much memory is free for
my application. I saw an article where say that I can look at _Workspace_Area.
If first == last, then there is only one free block of memory in the workspace
(very likely if no task deletions). For example, If I do this:
(gdb) p *(Heap Block *) _Workspace_Area->first
$3 = {back flag = 1, front flag = 68552, next = 0x1e260, previous = 0x1e25c}
I have 68552 bytes left in the workspace.
Below, I will post my gdb command output. Note: I'm running hello.exe example:
(gdb) p *(Heap_Block *) _Workspace_Area->first_block
$35 = {prev_size = 268439784, size_and_flag = 229, next = 0x101dd
<_ARMV7M_Exception_default>, prev = 0x101dd <_ARMV7M_Exception_default>}
The question is, How much is my free memory? I haven't "first" field on
_Workspace_Area.
You can use rtems_workspace_get_information() or malloc_info() for this purpose.
