Currently I'm trying to save different motor configurations ("profiles") to EEPROM, and for that I have to copy a struct to an array that could be sent via I2C. But when I try to declare the array, the application goes to the abort() function in exit.c.
Here is the function where the problem appears (happens when executing the line "uint16_t rawData8[len];"):
uint16_t EEPROM_saveProfile(HAL_Handle halHandle, Profile *profile, uint16_t profileNumber){
uint16_t len = sizeof(Profile)*2;
uint32_t address = profileDataStartAddr + len * profileNumber;
// Making sure we don't go beyond the avaliable memory.
if((address+len > EEPROM_SIZE) || (address+len > profileDataStartAddr+profileDataSize)){
return 0;
}
uint16_t rawData8[len];
convert16_8lsb(profile, rawData8, len);
return eepromWrite(halHandle->eepromHandle, address, rawData8, len);
}I verified that len=60 when the line in question is reached, and also tried to set it to a constant 60 rather than calculate it from the size of the profile, but the behavior didn't change. Commenting out the last 2 lines and setting len=1 still causes the program to abort there.
After digging deeper I found that abort() is called from increase_curr_vla_pool_capacity() in vla_alloc.cpp after realloc() returns 0 because curr_vla_pool->capacity * sizeof(a_vla_allocation) is 0. These files aren't part of my project (they are in the lib/src folder of the compiler).
First I thought the problem appears because some section runs out of memory, so I changed the .cmd file so that there is a lot of free space in each memory block by connecting all similarly named consecutive memory blocks in each page, but that didn't solve the problem. Here it is what it currently looks like:

}Any way to fix that?
P.S. Just in case it's relevant, I'm using proj_lab09 from Motorware 17 as basis for this project, but it was changed a lot already.
