I'm working with Atmel Start code on SAME54, having an issue with the I2C driver.
If I make a project using the master "sync" I2C driver, that works with default clocks at 12MHz.
It also works if I set the CPU clock up to 120MHz (I2C GCLK still at 12MHz).
If I make a project using the master "async" I2C driver (not the RTOS one), that also works with default clock at 12MHz.
But if I set the CPU clock up to 120MHz (again still using same 12MHz GCLK for I2C), I start getting calls to the error handler.
The code is -5 which is a bus error.
I'm now starting to study with a scope, but wondering if anyone has seen this one?
