thanks. How did you do the measurements that got you this 1.5x factor?
This afternoon I re-measured the I2C bus clock frequency with the oscilloscope at the I2C clock line on our Socrates MPC8544 board. With the patch applied, I measured the correct frequency of 100 kHz. Without, it was a factor of 1.5 too high.
are you able to change cfg_seq_freq on the board?
At least I don't know how. It's defined via hardware strap, I imagine.
Its is.. not sure if you have schematics for the board. If you do look to see if LWE_B is wired to anything.
