During these desperate time I bought some TI chips via Taobao instead of TI directly (no stock).
I assembled about ten boards and they all show similar behaviour:
With the chips in place I cannot get the I2C clock high.
When I remove the chips, the bus responds again.
Instead of jumping to conlusions (chips are fake); has there been some silicon change recently?
I have produced 100's of working boards with this chip, but now.
How to proceed?
