From 5d2e8d6d42c2cd0841074f3471d9a363a4840637 Mon Sep 17 00:00:00 2001 From: Jonathan McDowell Date: Tue, 3 Apr 2018 21:51:29 +0100 Subject: [PATCH] Update Makefile to link 2 separate ROMs Build 2 combined ROM images targeted at the top + bottom half of a 512kB ESP8266 device. This is a necessary pre-requisite to being able to do an over-the-air upgrade. --- Makefile | 20 +++--- rom0.ld | 211 +++++++++++++++++++++++++++++++++++++++++++++++++++++++ rom1.ld | 211 +++++++++++++++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 433 insertions(+), 9 deletions(-) create mode 100644 rom0.ld create mode 100644 rom1.ld diff --git a/Makefile b/Makefile index 3e0ffec..9fdad10 100644 --- a/Makefile +++ b/Makefile @@ -8,26 +8,26 @@ OBJDUMP = $(SDKDIR)/bin/xtensa-lx106-elf-objdump LIBS = -lc -lhal -lphy -lpp -lnet80211 -llwip -lwpa -lmain -LD_SCRIPT = eagle.app.v6.ld - CFLAGS = -Wall -Os -fno-inline-functions -mlongcalls -DICACHE_FLASH -I.
