The PR removed the bulk of non-newlib headers from the NodeMCU source base.
app/libc has now been cut down to the bare minimum overrides to shadow the
corresponding functions in the SDK's libc. The old c_xyz.h headerfiles have been
nuked in favour of the standard <xyz.h> headers, with a few exceptions over in
sdk-overrides. Again, shipping a libc.a without headers is a terrible thing to do. We're
still living on a prayer that libc was configured the same was as a default-configured
xtensa gcc toolchain assumes it is. That part I cannot do anything about, unfortunately,
but it's no worse than it has been before.
This enables our source files to compile successfully using the standard header files,
and use the typical malloc()/calloc()/realloc()/free(), the strwhatever()s and
memwhatever()s. These end up, through macro and linker magic, mapped to the
appropriate SDK or ROM functions.
* Rebaseline firmware to non-OS SDK version 3.0
* Note that SDK version 3.0 introduces the concept of a Flash Partition Table(PT). This is located at Flash offset 0x10000 in our firmware build.
* The firmware is now PT aware with both LFS and SPIFFS taking their partition size and location from the PT
* A new tool `tools/nodemcu-partition.py` is now used to initialise these data and can also download LFS and SPIFFS images to these partitions.
* Add FatFs
* enable BUILD_FATFS for all-module build
* push vfs into rest of firmware
* align maximum filename length
* increase timeout for acmd41 during card initialization
* switch from DOS to Unix path semantics chdrive() is substituted by chdir()
* update to fatfs R.012a incl. patches 1-6
* add callback for rtc provisioning in file
* update docs
Fixes#1164 and thus also #1150, #1149, #1147 and #898.
* Move to latest version of SPIFFS
* Add SPIFFS porting layer for NodeMCU
* Add option to delete output if it doesn't fit
* Change FLASHSIZE to be in bits by default: default 4mb 32mb
* Add SPIFFS_MAX_FILESYSTEM_SIZE override
* Add notes on SPIFFS_FIXED_LOCATION
* Add 1M boundary
* Include the current version of the LICENSE
There was only one genuine use of this macro, all other places were
using it only as a necessary compensation. While this was fine as long as
it was the first meg of flash which was mapped, it became incorrect and
quite dangerous whenever this assumption did not hold (such as when
running from the second slot in an OTA scenario).
The flash API now uses actual addresses, not translated/mapped
addresses, and the users of this API have been adjusted accordingly.
This makes the flash API work correctly regardless of what flash mapping
is in use.
The old macro is still available under the new name
INTERNAL_FLASH_MAPPED_ADDRESS, and this is used to detect flash writes
where the source is mapped flash (and thus has to be bounced), and to
adjust the _flash_used_end linker symbol when used with
flassh_find_sector() by the filesystem code. The latter usage is not
OTA-proof, but in an OTA scenario the filesystem needs a fixed location
anyway and thus would not use this code path.
Also made the cache on/off configurable via user_config.h. Uncached writes
are not a very good idea, but for read-only deployments a further ~0.5k RAM
can be gained by disabling the cache.
Tweaked the file.read() workhorse to read large chunks at a time rather
than use getc(), to compensate for potential unavailability of cache.
