Hello,

I am currently trying to run an initialization script through ALP (v1.57.0010) and USB2ANY (USB2ANY A7C3B06F22001300) and there is no I2C bus activity (bus stays HI), but the ALP window shows that the code is running.

I have tried two different boards with the same result. Do you know what may be causing this?

Hi Luis,

What device/device profile are you running in your version of ALP?

Regards,
Jonny

Hi Jonny

It is for an unreleased deserializer device.

Just to add - the bus appears to be LOW in most instances.
