Sander,

Just tested with "i2cdetc -y -r 0" that crashes with "BUG: soft
lockup -
CPU#0 stuck for 22s!"
according to the docs (IMX23RM.pdf) the interrupts for I2C are 26
and 27
that why I assigned these two in the dts.


In your dts, is it 26, 27? Order matters, it should be 27, 26.
Error ISR,
DMA.


Hi Tim,

Thanks for your suggestion. I swapped the numbers and it solved the crash.
However I still have to debug some more because it gives now :
mxs-i2c 80058000.i2c: Failed to get PIO reg. write descriptor.

Thanks,

Sander
