I encountered this error when configuring I2C2 on H7A3 board, fast mode, i2c enabled, and code auto generated from ioc. anyone can kindly advise?
MX_I2C2_Init used but never define
2023-09-30 06:17 PM
full error msg: ../Core/Src/main.c:211:13: error: invalid storage class for function 'MX_I2C2_Init' at line that say : static void MX_I2C2_Init(void);
whats happening ??
2023-09-30 10:49 PM
Missing forward declaration for MX_I2C2_Init?
2023-10-01 06:38 AM
the I2C2 was generate from the ioc GUI, how could it be missing? Any idea ?

Include the relevant files (main.c and *.ioc).

Hello @StanCosgrove ,
I couldn't reproduce this issue .
Could you please share the .ioc file ?
