With the IDF asserting full control over the linker scripts and insisting on
the application description being the first entry in the .flash.rodata
section, or previous method of doing link-time arrays stopped working.
Why? Because the build patched in a SHA256 digest straight into our arrays.
With the limited language of the gcc linker scripts I could find no other
way of getting it in cleanly.
The IDF "linker fragments" support can not be made to work for our needs:
- no support for setting alignment before including objects
- no support for declaring symbols
- no support for adding our terminating zeros
- insists on grouping objects by lib rather than by declared grouping,
which means we could at most have a single link-time-array using
the IDF mechanism
- also does not like underscores in section names, but that's just an
annoyance
So, the least bad option that I could come up with was to use a project-wide
makefile snippet to add a target in-between the IDF's generation of the
esp32.project.ld file, and the linking of our NodeMCU.elf. In this target
we read in the esp32.project.ld linker script, check whether we have our
arrays in there, and if not rewrites the linker script.
Oh, and the esp32.project.ld file only came into existence on the IDF 3.3
branch, so I had to change up the IDF to the latest release/3.3 as well.
I would've preferred a stable tag, but the v3.3-beta3 had a really nasty
regression for us (can't add partition entry), so that was a no-go.

This commit adds support for switching UART mode to RS485/IRDA.
Also included are patches for memory leaks then handling UART events other than data.
* ESP32: Documentation for uart.setmode()
* ESP32: Add time modules
New time module for manipulating system time/ calendar and controlling SNTP server
* ESP32: Time module documentation & style fixes

* style fixes as pointed out by @devsaurus
* ESP32: Time module small fixes
* Couple small fixes
* Esp32: Add SJSON module
This adds SJSON module taken directly from master
* ESP32: Fixes for sjson lib
Fixed compilation not including config header, thus braking some of libs functionality
* ESP32: Upgraded SJSON to master
* Adding qrcodegen module for generating QR Codes
* Added LUA_MODULE_QRCODEGEN KConfig
* Changed qrcodegen.encodeText() to use an options table
Created common.h with new option table helper fns.
* Reworked http.c to use new common.h options table APIs
* esp32: Reinstate tmr.now() function using esp_timer_get_time()
Also added larger limit before wrapping if Lua's number type supports
it.
* Renamed tmr.now() to node.uptime()
Added second return value to indicate timer wrap
- implement file.size for spiffs (#1516)
- fix vfs_lseek() result checking in enduser_setup and clarify SPIFFS_lseek() return value (#1570)
- Handle error condition in file.read() (#1599)
* #2521: Add object-based file API to dev-esp32 branch
Merged in from master@c708828bbe853764b9de58fb8113a70f5a24002d minus
some VFS changes and similar.
* Updated file docs from master
Omitting:
* file.mount()
* reference to rtctime.epoch2cal()
* file.stat()
As these are not available in dev-esp32 branch
Unsure about whether "directories are not supported" is still true
* Set stdout to unbuffered
This fixes issue #2507 esp32 serial console doesn't show output until
enter pressed.
* Moved setvbuf call to app_main immediately after console_init
* Inital commit for supporting ledc driver
* Added documentation. More fade functions and better naming of constants
* Better field checking during setup. Updated documentation
* Reworked LEDC module to be used with an object model to decrease repetition of parameters
* uart 1/2
* call -> pcall in uart_on_* functions
* fix docs
* fixed console driver when using custom console uart
* fixed line_inverse and error callback
* fixed a crash when uart.start() called more than one time
* can extension
* can extension: bit timing and filter
* can -> CAN
* post CAN data callback
* CAN docs
* CAN: fixed receive, filter, extended frame
* reorder fn in can.md, remove driver_can/Kconfig
* fixed a leak when can.stop()
- Switched hardcoded interrupts to new IDF interrupt allocation
framework.
- gpio module switched to the IDF's per-pin interrupt callback service.
- Improved NodeMCU linker script since it broke with the IDF upgrade.
- Various compatibility updates.
This fixes the panic-on-restart issue and the crash-on-uart-input-before-flash-mapped issue.
Node module updated to reflect new function names for sleep/restart.
With the recent flash layout changes, it became very possible to misdetect the
flash size. We're now using the partition table as the guard marker, since
that really shouldn't be all 0xff. Also, we now don't clobber the flash
device id (and keep block/sector/page/mask values).
WiFi STA module updated to reflect IDF name changes.
Platform flash and partition api updated to reflect IDF name changes.
Eventually these (and the SPIFFS module) will likely need to be updated
to exclusively work with the esp_partition_xxx() functions in order to
support working with encrypted flash.
Based on his revision 2d290a24a0914be88e5ca4ac7b1018392fe75fe2
(https://github.com/djphoenix/nodemcu-firmware).
All LWIP callback handling changed to use the NodeMCU task interface
to make it usable on RTOS.
IPv4 assumptions have been removed, and this net module /should/ now
be IPv6 ready, but aside from compilation no testing has been done
in this area.
SSL integration points not touched - some work needed there once we
have an mbedTLS module.
node.dsleep() no longer takes options.
node.output() not yet supported (needs syscall registration/chaining support)
Dynamic CPU frequency changing not currently supported in the IDF.
Various chip IDs not currently available/obtainable.
Boot reason completely revamped in ESP32, will need new code.
