Fabio Estevam 76c91e668a mx6: Disable Power Down Bit of watchdog ... On a mx6qsabresd revision C board with rev1.2 mx6q, the system gets resetted and it is not able to reach the Linux prompt. Comparing the watchdog behaviour on a revB versus revC board: - On a mx6qsabresd revB: U-Boot > reset resetting ... U-Boot 2013.01-10524-g432a3aa-dirty (Feb 07 2013 - 13:34:46) CPU: Freescale i.MX6Q rev1.1 at 792 MHz Reset cause: WDOG ... - On a mx6qsabresd revC: U-Boot > reset resetting ... U-Boot 2013.01-10524-g432a3aa-dirty (Feb 07 2013 - 13:34:46) CPU: Freescale i.MX6Q rev1.1 at 792 MHz Reset cause: POR So due to revC POR/watchdog circuitry whenever a watchdog occurs, it causes a POR. Clearing the PDE - Power Down Enable bit of WMCR registers fixes the problem and is also safe for all mx6 boards.
