|
* The non-OS SDK prolog has been fundamentally revised in V3. See SDK EN document
|
||
|
|
* Partition Table.md for further discussion. This version of user_main.c is a
|
||
|
|
* complete rework aligned to V3, with the redundant pre-V3 features removed.
|
||
|
|
*
|
||
|
|
* SDK V3 significantly reduces the RAM footprint required by the SDK and introduces
|
||
|
|
* the use of a partition table (PT) to control flash allocation. The NodeMCU uses
|
||
|
|
* this PT for overall allocation of its flash resources. The non_OS SDK calls the
|
||
|
|
* user_pre_init() entry to do all of this startup configuration. Note that this
|
||
|
|
* runs with Icache enabled -- that is the IROM0 partition is already mapped to the
|
||
|
|
* address space at 0x40210000 and so that most SDK services are available, such
|
||
|
|
* as system_get_flash_size_map() which returns the valid flash size (including the
|
||
|
|
* 8Mb and 16Mb variants).
|
||
|
|
*
|
||
|
|
* The first 4K page of IROM0 (flash offset 0x10000) is used to maintain a set of
|
||
|
|
* Resource Communication Records (RCR) for inter-boot configuration using a NAND
|
||
|
|
* write-once algo (see app/platform/platform.h). One of the current records is the
|
||
|
|
* SDK3.0 PT. This build statically compiles in an initial version at the start of
|
||
|
|
* the PT, with a {0, _irom0_text_end,0} marker as the last record and some fields
|
||
|
|
* also that need to be recomputed at runtime. This version is either replaced
|
||
|
|
* by first boot processing after provisioning, or by a node.setpartitiontable()
|
||
|
|
* API call. These replacement PTs are complete and can be passed directly for use
|
||
|
|
* by the non-OS SDK.
|
||
|
|
*
|
||
|
|
* Note that we have released a host PC-base python tool, nodemcu-partition.py, to
|
||
|
|
* configure the PT, etc during provisioning.
