We're using a DRA746 (at least, I'm *pretty* sure that's the one...), and we're seeing something odd from time to time.
We get a "WARNING: MASTER MPU TARGET HOST CLK2 (Idle): At address: 0x00000000: Data Access in User mode during Functional Access". The address isn't always zero depending on the source.
We understand the "MASTER MPU" but what is the "TARGET HOST CLK2"?
We cannot find anything in the manual that shows a CLK2 as such. There's HOST_CLK1_1, HOST_CLK1_2, and HOST_CLK2_1. Should the label read "HOST CLK2 1"?
Most importantly, what causes this? We've seen it happen in a few cases. When it happens during a USB2 access (via the USB3 controller), the warning message never stops, which for all intents and purposes makes the system unusable. It's been observed during an I2C access (it happened two times in a row back-to-back during a set of I2C transactions), and it's been observed happening during other uses which don't lock up the system.
Thanks,
