Sorry for replying to myself, but thought I'd mention SRESET works fine on 85xx 2.6.23 , ie, the board resets after kernel panic. It doesn't work for me on 2.6.24rc2 .What actual 85xx are you using? - kCustom 8548 board. I'm using the cds 85xx code for a reference and I calling the same reset functions.1. do you have the following in your dts: global-utilities@e0000 { //global utilities reg compatible = "fsl,mpc8548-guts"; reg = <e0000 1000>; fsl,has-rstcr; };
Yes.
2. in your platform code are you using fsl_rstcr_restart in define_machine() - k
Yes. The symptoms in 2.6.24RC2 are that during a kernel panic or when calling 'reboot' in the shell, it just hangs. Using the same dts and resets in 2.6.23.1 reboots fine. I don't have a cds reference, but someone who does should be able to confirm whether the issue exists or not by just attempting to reboot via bash. Robert
