FW 5.0.1 compiled sketch too big out of the box

[vegasbrad]

I messaged Chris H about this tonight and was wondering if any one else has ran into this.

I built a charging station kit I've had for awhile and want to update the FW to 5.0.1  I DL'ed 5.0.1 tonight and Arduino 1.6.5 is giving me an error that the sketch is too big. It's at 105% with no edits done. I tried to delete a few things hoping to make room but it didn't help, I deleted the two Mennekes files on a guess (as I'm not using a Mennekes lock) in the firmware folder that contains the plethora of files (libraries?) and the open_evse file. After spending a few hours I'm stuck. I can't understand why the sketch is too big right out of the box.

Check the version of build tools you may have to download an older version. If you are building and testing you own build you can also try the latest development version at lincomatic GitHub.

• Current official build tools version is Arduino AVR Boards by Arduino v1.6.15. You can install any version of the GUI, but make sure to use that version of the build tools, as it was used for UL certification. WITH LATEST CHANGES, v1.6.15 results in a sketch that's too big (>32768). MUST DISABLE FEATURES TO BUILD A COMPATIBLE SKETCH.. disabling RAPI_WF does the trick.

Thanks for the quick response Chris, I looked at https://www.arduino.cc/en/Main/OldSoftwareReleases#previous for older Arduino IDE software and it skips from 1.6.13 to 1.8.0 Is 1.6.15 the correct number?  I'm trying to wrap my head around the terms, perhaps I'm not following you.

Won't disabling RAPI_WF disable communication via the header that the wifi module plugs into?

Open Arduino

Select Tools

Boards: Board Manager...

Find Arduino AVR Boards

Change version to 1.6.15

Select Install

Thanks for the detailed steps, I did that. Now under the Tools, Board, drop down, "Open EVSE programmer" is no longer listed. I chose Arduino/Genuino Uno and The sketch does compile and ends up at 99% but it wont load, I get

avrdude: stk500_recv(): programmer is not responding

[vegasbrad]

for programmer I still have USBasp selected

[chris1howell]

You need to select "Upload using programmer" under Sketch

I tried that and also using the checkmark button , i get;

Sketch uses 32,012 bytes (99%) of program storage space. Maximum is 32,256 bytes.
Global variables use 1,546 bytes (75%) of dynamic memory, leaving 502 bytes for local variables. Maximum is 2,048 bytes.
Low memory available, stability problems may occur.

[vegasbrad]

is there something about boards.txt that needs to be changed? a vaguely remember something from years ago, is this related to getting [Programmer]OpenEVSE back as a option?

[vegasbrad]

I followed this guys post and selected [Programmer]OpenEVSE  but now it wont even compile :

Steve Waltner

said almost 5 years ago

OK, I finally was able to compile the code that I downloaded from https://github.com/OpenEVSE/open_evse.

To correct the compilation error, I just downgraded my copy of the Arduino toolset from version 1.6.6 down to 1.6.5. For whatever reason, the stable code branch available now doesn't compile cleanly using the latest toolset. While I understand that I could have added the function prototypes, until I learn a little more about Arduino in general and OpenEVSE in particular, I'm going to keep it as simple as possible.

To correct the second issue that we ran into, with the compiler saying the resulting code object is too large, adding the board definition worked. There apparently are multiple ways to define new board/connection types. I did this by selecting Arduino->Preferences and then entering https://github.com/chris1howell/Arduino_Board_Manager/releases/download/v0.1/package_OpenEVSE_328p_index.json in the "Additional Board Manager URLs" field, closing that dialog box, then selecting "Tools->Boards->Board Manager", selecting the OpenEVSE entry and then clicking Install. "[Programmer]OpenEVSE" was now a board type.

After downgrading the toolset and installing the custom board type, the current code set compiles cleanly. Just hoping this helps others as they work through this process.

now i get:

C:\Program Files\Arduino\hardware\tools\avr/bin/avr-gcc -c -g -Os -w -std=gnu11 -ffunction-sections -fdata-sections -MMD -flto -fno-fat-lto-objects -mmcu=atmega328p -DF_CPU=16000000L -DARDUINO=10605 -DARDUINO_AVR_UNO -DARDUINO_ARCH_AVR -IC:\Users\Brad\AppData\Roaming\Arduino15\packages\arduino\hardware\avr\1.6.15\cores\arduino -IC:\Users\Brad\AppData\Roaming\Arduino15\packages\arduino\hardware\avr\1.6.15\variants\standard C:\Users\Brad\AppData\Local\Temp\build6683425470897689960.tmp\twi.c -o C:\Users\Brad\AppData\Local\Temp\build6683425470897689960.tmp\twi.c.o
cc1.exe: error: -fno-fat-lto-objects are supported only with linker plugin.
Error compiling.

i tried switching back to uno for the board and get the same error

[vegasbrad]

i uninstalled Arduino_Board_Manager , closed IDE and relaunched, now it compiles fine again, i tried upload with programmer again and get:

Sketch uses 32,012 bytes (99%) of program storage space. Maximum is 32,256 bytes.
Global variables use 1,546 bytes (75%) of dynamic memory, leaving 502 bytes for local variables. Maximum is 2,048 bytes.

also the power light on my openevse programmer is on but the busy light never comes on so even though the IDE screen says uploading i know its not.

sooo frustrating!

[vegasbrad]

i need to post the way back out of the rabbit hole here for reference

i tired to install fw v 3.11.3 to test and now i cant even do that, i get avr dude not recognizing programmer. so i upgraded boards ver back to 1.6.5, still errror, reinstalled Programmer Openevse and now its back to working before i started all this.

given the previous post what am i missing?
