I2C address not sent from STM32F103C8T6 Master to I2C-LCD Slave

Hello,I have troubles using I2C with the STM32F103C8T6 "Blue Pill" board. I set up the code in CubeMX, using LL Libraries. After initializing the I2C periphery I try to send the address, but the ADDR bit in I2C1_SR1 register remains 0. AF bit remains...

Does the STM32 v1.5.1 GCC 7.3.1 toolchain have a limitation of 32-bit arguments for variable argument lists (stdarg.h) ? I am trying to pass 64-bit arguments via a variable argument list and I only see the upper 32-bits set (lower 32-bits are zero).

I'm using the standard ANSI va_args approach here: int64_t arg64 = va_arg(args, int64_t);When stepping through the code the debugger clearly shows me a value like: 0xbeefbeef00000000
