I2C Demo for STM32L4R5ZI

[Tabulous]

Is there a demo for STM32L4R5ZI ?
I'm running into MasterTimeout Halt

Looked at the F3 as this is v2 driver but clock tree is different.
Also have GPIO set as OD

Hi,

What is the message passed to chSysHalt()? note there is a pointer to string passed as parameter.

it fails on this
osalDbgAssert(i2cp->state == I2C_READY, "not ready");

First time around is ok as state is I2C_READY, but the second time it is I2C_LOCKED.

Reason is 0x8016b24 <__func__.3.lto_priv.5> "i2cMasterTransmitTimeout"

Also does not look to be any clock on the SCL line..... Almost like the peripheral is not running / been clocked

Hi,

Make sure that clock settings in the configuration structure are correct for considering the input clock, there is a chapter in the RM about this.

Also possible, a GPIO problem make sure to program correctly both lines.
