## Summary When MSI clock is selected at 48MHz this change is needed to avoid a hang on boot. It appears that setting the MSION bit when already on brought this problem. At the same time, using this higher clock value triggered the selection of the range 1 for core regulator and this also hung during boot. I could not find out why this problem occurs but since this is the default behavior it should introduce any different behavior. Finally, with this clock speed there wasn't a matching case for the I2C clocking computations. I used ST's tool to get the values for this case. This now allows using I2C with MSI@48MHz as SYSCLK ## Impact Selection of MSI clock at 48MHz frequency as system clock ## Testing I'm using I2C at 48MHz with MSI on STM32L476 and can communicate correctly ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
