PL I2C driver read/send timeout #10

Open mpv89 opened 5 years ago

mpv89 commented 5 years ago

There is a major bug somewhere in the I2C driver where after a few operation (unclear how many) the driver won't be able to talk to the PL interface which will cause operations to timeout.

It is unclear exactly what is happening but this is likely related to the problem seen before where sending and receiving 1byte sometimes cause the PL logic to lock and nothing recovers it.
