FOTA example

[fvpalha]

Hi Richard.

I am developping with Unofficial Development Kit for Espressif ESP8266 and I want to add FOTA feature in our project.

I am studing the rboot-sampleproject, but this error occurs:

mingw32-make.exe -f C:/Trabalho/raburton-esp8266-master/rboot-sampleproject/Makefile all 
CC main.c
In file included from main.c:16:0:
rboot-ota.h:12:23: fatal error: rboot-api.h: No such file or directory
compilation terminated.
mingw32-make.exe: *** [build/main.o] Error 1

Do you have a tip?

Best regards.

Hi Richard.

I do this:

3) Symlink or copy rboot.h, rboot-api.h and rboot-api.c in to this directory.
4) Edit the Makefile to set the paths to the SDK and esptool2.
5) Set WIFI_SSID & WIFI_PWD as env vars or in the makefile.

and the result was:

mingw32-make.exe -f C:/Trabalho/raburton-esp8266-master/rboot-sampleproject/Makefile all

Did you copy the files in to the sample directory, as per the instructions in the readme? Also rememeber to set SDK_BASE. If you do it compiles fine here with UDK:

D:\Projects\esp8266\rboot-sampleproject>ls
Makefile              rboot-api.c           rom0.ld
blank4.bin            rboot-api.h           rom1.ld
eagle.rom.addr.v6.ld  rboot-ota.c           uart.c

Best guess here you have some odd characters in WIFI_SSID & WIFI_PWD.

Hi Richard.

I edited the Makefile:

#
# Makefile for rBoot sample project
# https://github.com/raburton/esp8266
#

# use wifi settings from environment or hard code them here
WIFI_SSID ?= "dd-wrt"
WIFI_PWD  ?= "ESP8266@"

# Base directory for the compiler
XTENSA_TOOLS_ROOT ?= c:/Espressif/xtensa-lx106-elf/bin

#SDK_BASE   ?= /opt/esp-open-sdk/sdk
SDK_BASE    ?= c:/Espressif/ESP8266_SDK
SDK_LIBDIR  = lib
SDK_INCDIR  = include

ESPTOOL2     ?= ../esptool2/esptool2
FW_SECTS      = .text .data .rodata
FW_USER_ARGS  = -quiet -bin -boot2

and SET the environment variable SDK_BASE

SDK_BASE    ?= c:/Espressif/ESP8266_SDK

But this not solve the problem.

[raburton]

Which problem? You appear to have already got past the original problem you reported.

That whole page of errors you posted next appears to be complaining about the variables WIFI_SSID & WIFI_PWD. I assume you have some none standard characters in them, which probably need to be escaped to become valid C strings. e.g. if your password has a \ in it it'll need to be replaced with \, etc.

Hi Richard.

I changed the Makefile, I removed the "" in:

WIFI_SSID ?= dd-wrt
WIFI_PWD  ?= ESP8266@

and now this occurs:

mingw32-make.exe -f C:/Trabalho/raburton-esp8266-master/rboot-sampleproject/Makefile all 
CC main.c
CC rboot-api.c
CC rboot-ota.c
CC uart.c
LD rom0.elf
FW rom0.bin
process_begin: CreateProcess(NULL, ../esptool2/esptool2 -quiet -bin -boot2 build/rom0.elf firmware/rom0.bin .text .data .rodata, ...) failed.
make (e=2): O sistema não pode encontrar o arquivo especificado.

mingw32-make.exe: *** [firmware/rom0.bin] Error 2

Thank you Richard.

I opened the prompt, and:
