/* The i.MXRT1060-EVK has 8MiB of Hyper FLASH beginning at address,
|
2020-02-22 19:31:14 +01:00
|
|
|
* 0x0060:0000, Up to 512Kb of DTCM RAM beginning at 0x2000:0000, and 1MiB OCRAM
|
2018-11-09 14:56:02 +01:00
|
|
|
* beginning at 0x2020:0000. Neither DTCM or SDRAM are used in this
|
2020-02-23 09:50:23 +01:00
|
|
|
* configuration.
|
2018-11-09 14:56:02 +01:00
|
|
|
*
|
|
|
|
|
* The user and kernel space partitions will be spanned with a single
|
|
|
|
|
* region of size 2**n bytes. As a consequence, as the partitions increase
|
|
|
|
|
* in size, the alignment requirement also increases. The sizes below give
|
|
|
|
|
* the largest possible user address spaces (but leave far too much for the
|
|
|
|
|
* OS).
|
|
|
|
|
*
|
|
|
|
|
* The solution to this wasted memory is to (1) use more than one region to
|
|
|
|
|
* span the user spaces, or (2) poke holes in a larger region (via sub-
|
|
|
|
|
* regions) to trim it to fit better.
|
|
|
|
|
*
|
|
|
|
|
* A detailed memory map for the 512KB SRAM region is as follows:
|
|
|
|
|
*
|
|
|
|
|
* 0x2020 0000: Kernel .data region. Typical size: 0.1KB
|
|
|
|
|
* ------ ---- Kernel .bss region. Typical size: 1.8KB
|
|
|
|
|
* 0x2020 0800: Kernel IDLE thread stack (approximate). Size is
|
|
|
|
|
* determined by CONFIG_IDLETHREAD_STACKSIZE and
|
|
|
|
|
* adjustments for alignment. Typical is 1KB.
|
|
|
|
|
* ------ ---- Padded to 4KB
|
|
|
|
|
* 0x2040 0000: User .data region. Size is variable.
|
|
|
|
|
* ------- ---- User .bss region Size is variable.
|
|
|
|
|
* 0x2042 0000: Beginning of kernel heap. Size determined by
|
|
|
|
|
* CONFIG_MM_KERNEL_HEAPSIZE.
|
|
|
|
|
* ------ ---- Beginning of user heap. Can vary with other settings.
|
|
|
|
|
* 0x2080 0000: End+1 of mappable OCRAM
