Makefile is altered to use this file ahead of the SDK's. Remove lwip's sntp support, since it was never really wired in anyway. See https://github.com/nodemcu/nodemcu-firmware/issues/2042 for more information. Patch Makefile to strip time.o, the consumer of lwip's sntp functionality, from libmain.a, resulting in much easier-to-understand error messages. This has consequences for mbedtls. The simplest thing to do, which is, impressively, not a change in behavior, is to completely disable TLS certificate time validation; a later patch can optionally couple this to RTCTIME support. Similarly, it happens that the sqlite3 import was calling time(), but this was not going to work out well for it. Just stub it out to always return unix timestamp 0, as would have happened anyway. Changes unprocessed: 0007-sync-from-080c37e1.patch 0008-feat-lib-Compile-some-libraries-with-ffunction-secti.patch These two make changes to the linker script; perhaps they are worth porting over, but I have not done so here. This is build-tested (ADC, BIT, COLOR_UTILS, CRON, CRYPTO, DHT, ENCODER, FILE, GPIO, HTTP, I2C, MQTT, NET, NODE, OW, PCM, PERF, PWM, RTCFIFO, RTCMEM, RTCTIME, SNTP, SPI, SQLITE3, STRUCT, TLS, TMR, UART, WIFI, WS2812, WS2812_EFFECTS) and boots, but only limited run-time testing has been performed. Testing done does, however, include having made a few TLS connections through the HTTP module, so things are not hopelessly broken, at the very least.
