The version number is written on the CPU board. warp rev1.0 did not connect the WDOD1_WDOG_B pin to the PMIC and is not capable of resetting the system. warp7 rev2.0 does connect the WDOD1_WDOG_B pin to the PMIC and the reset works fine. I also found a workaround to reset the rev1.0 board: it consists in setting bit 0 of SRC_A7RCR0 register. _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
