Problem with uart_lld.c

[Giapptvn1412]

Am I not configuring something correctly here? when i wirte #include "hal.h" in the file uart_lld.c. Keil C error I2c2 not present in the selected device.
Who can answer me? Thank you very much

[Giovanni]

Hi,

Just read this part "I2c2 not present in the selected device".

Disable I2C2 in mcuconf.h.

Can i init I2c2 if disable i2c2 in mcuconfig.h. my understanding, is enabled I2C2 when #define STM32_HAS_I2C2 TRUE and #define STM32_I2C_USE_I2C2 TRUE

[Giovanni]

Apparently your device does not have I2C2 so you cannot initialize it.

Thank you for the answer. . My Device STM32F103s8t6. I want to initialize the I2С2. How to enable the I2C2 to use slave? I'm sory, I'm new to chibios.

[Giovanni]

Hi,

The STM32F103T6 does not have I2C2.

Hi. I think there's something.
STM32F103C8T6 has I2C2.

Hi,

Do you have a custom board.h?

Make sure to define STM32F103xB in board.h, x8 devices are not directly supported, xB are the closest ones.

What ChibiOS version are you using? that board file is very old.
