Description
There is a bug in the state machine for the I2C driver. When sending the first address byte / cmd the state of the state machine is set, and then the byte in sent, if an MBUS interrupt occurs BEFORE the code has set the state, then the state machine locks up.
Release:
RTEMS-4.5
Environment:
Cygwin / Coldfire 5307
How-To-Repeat:
Send continous messages using the I2C bus
