Hi All,
I am using PlatformIO to build a firmware for rp2040 devices, for my OTA procedure I need a .bin file.
Now for a long time PlatformIO did create .bin files, but for some time now it seemingly randomly switches between creating only .elf files and .bin files.
First of all I wonder why this is happening. I have the hunch that it is related to the size of the firmware, but I could not verify that yet.
Here is my platformio.ini:
[env:pico]
platform = GitHub - maxgerhardt/platform-raspberrypi: Raspberry Pi: development platform for PlatformIO
board = pico
framework = arduino
board_build.core = earlephilhower
lib_deps = adafruit/Adafruit NeoPixel@^1.12.0
monitor_speed = 115200
build_flags =
-DUSE_TINYUSB
-DCFG_TUSB_CONFIG_FILE="myConf.h"
-Iinclude/board_build.filesystem_size = 1.6m
extra_scripts =
pre:buildscript_versioning.py
; post:build_script.py
as you can see I tried to force the creation of a .bin file with a post build script, but when I run that I run into output that I cant make sense of, here’s the script:
from os.path import join
Import(“env”, “projenv”)# Custom BIN from ELF
env.AddPostAction(
“$BUILD_DIR/${PROGNAME}.elf”,
env.VerboseAction(" ".join([
“$OBJCOPY”,
“-O”,
“binary”,
“$TARGET”,
“$BUILD_DIR/${PROGNAME}.bin”
]), “Building $TARGET”))
the output is:
Linking .pio\build\pico\firmware.elf
Generating UF2 image
elf2uf2 “.pio\build\pico\firmware.elf” “.pio\build\pico\firmware.uf2”
Building .pio\build\pico\firmware.elf

*** [.pio\build\pico\firmware.elf] Error 1
So my main question is, How can I make sure that i always get .bin file output, what am I missing here?
Thanks!
