compile problem on v0.9.5 .

[younger]

Hi Espressif:
I just want to add smartconfig(smartconfig_start) into the IOT_demo,but it compiles with a problem:

Code: Select all

make: Warning: File `.output/eagle/debug/image/eagle.app.v6.out' has modification time 14 s in the future
xtensa-lx106-elf-gcc  -L../lib -nostdlib -T../ld/eagle.app.v6.new.512.app1.ld -Wl,--no-check-sections -u call_user_start -Wl,-static -Wl,--start-group -lc -lgcc -lhal -lphy -lpp -lnet80211 -llwip -lwpa -lmain -ljson -lssl -lupgrade -lsmartconfig user/.output/eagle/debug/lib/libuser.a driver/.output/eagle/debug/lib/libdriver.a -Wl,--end-group -o .output/eagle/debug/image/eagle.app.v6.out
/opt/xtensa-lx106-elf/bin/../lib/gcc/xtensa-lx106-elf/4.8.2/../../../../xtensa-lx106-elf/bin/ld: .output/eagle/debug/image/eagle.app.v6.out section `.irom0.text' will not fit in region `irom0_0_seg'
collect2: error: ld returned 1 exit status
make: *** [.output/eagle/debug/image/eagle.app.v6.out] Error 1

But if I compile without "user_esp_platform_init();" and "user_webserver_init(SERVER_PORT);" , it will be OK. why?

That means your source code is too large to fit in .. try to compile as 1024KB flash , and use a 1024KB flash..

No ,I use "make COMPILE=gcc BOOT=new APP=1 FLASH=1024" , it also compiles error.

Yes，log “section `.irom0.text' will not fit in region `irom0_0_seg'” means your source code is too large to fit in
1、you can compile it as 1024KB flash and use 1024KB flash
2、delete some useless source code to make it fit in


If you need to compile as 1024 new，please unzip the attachment and replace them in \esp_iot_sdk_v0.9.5\ld

sorry for the inconvenience.

Hi Espressif:
yes,if i use 1024kb compile ,it will be OK.
But the compile result: user1.1024.new.bin just 221kB, in 512kB flash ,the user1 bin size could be 236kB ,remain 15kb !
why ?

[younger]

OH, I have found it.
The .irom0.text size is 0x2e2a4, and the limit is 0x2B000, so compile error.

So I just want to know what " .irom0.text " contains ?

Hi,
methods with "ICACHE_FLASH_ATTR" in irom0_0_seg
methods without "ICACHE_FLASH_ATTR" in iram1_0_seg

You could try this http://bbs.espressif.com/viewtopic.php?f=10&t=166

Or try to remove "ICACHE_FLASH_ATTR" from some methods, so they will be compiled to iram1_0_seg area.
