Hi @Laurent BEYLY ,Thanks for your answer and explanations. But at this point, we can not change the hardware link by using other pins.It's a big problem for us...Regards,Yvan
@Amel NASRI Another new additionnal tests :new CubeMx I2C slave project on a NUCLEO F446RE board : same problem... new CubeMx I2C slave project on a STM32F0308 - DISCO board : clock stretching is present, everything seems to be OK new CubeMx I2C sla...
Amel,CR1 = 0x0401 (peripheral enable=1 + ACK enable=1 + NOSTRETCH=0) : seems OKI've swaped the test on the other I2C peripheral : I2C1 => I2C3 : same result.SR1 and SR2 = 0....Regards,Yvan
