Error[Lp015]: section placement failure caused by HAL_Unlock???

Taco!

Im using an F4 and modified my code to support an analog input using CubeMX. It messed up my project directory so i copied the new adc files to my unharmed project. I now get an "Error[Lp015]: section placement failure: overcommitted content in [0x802'0000-0x803'ffff]" and "Error while running Linker".

Part of the code in the auto generated adc.c file is a function called MX_ADC1_Init();

If i call this function i get the above error. If it is commented out, it builds successfully. If i call that function but comment everything out it builds successfully. If I incrementally add things in until i get the error then it fails within the HAL_ADC_Init() function (which is within the MX_ADC1_Init() function). Within the HAL_ADC_Init() function it fails when I uncomment hadc->Lock = HAL_UNLOCKED;

The code below shows the hadc->Lock = HAL_UNLOCKED as uncommented. Has anyone seen this before? What could cause it? How do I fix it?

Edit: worth noting is that many other unlock statements work correctly (ie: huart->Lock = HAL_UNLOCK, htim->Lock = ..., heth, hspi, hi2c, hrng, etc.)

So, is the program just growing more than 128K?

I agree - ssupposedly your code size grew beyond Flash size.

Check the linker map file, to see which objects seize that much space.

AMap - a nice tool to look at *.map files.

Atollic and Cube IDE have a similar tool, the Build Analyzer.

Open it after successful build. For best results, check "generate list file" in post-build outputs.
