I'm not able to boot it, it does hang/crash in the device initcall: (...) [ 0.274656] initlevel:6=device, 135 registered initcalls [ 0.286256] msgmni has been set to 227 [ 0.289522] Block layer SCSI generic (bsg) driver version 0.4 loaded (major 252) [ 0.289548] io scheduler noop registered [ 0.289570] io scheduler cfq registered (default) [ 0.413953] mx3_sdc_fb mx3_sdc_fb: registered, using mode Epson-VGA [ 0.544110] Console: switching to colour frame buffer device 60x40 [ 0.555321] imx-sdma imx31-sdma: loaded firmware 1.0 [ 0.588970] imx-sdma imx31-sdma: initialized [ 0.590912] Serial: IMX driver [ 0.591139] imx21-uart.0: ttymxc0 at MMIO 0x43f90000 (irq = 45) is a IMX [ 1.260201] console [ttymxc0] enabled [ 1.278640] spi_imx imx31-cspi.1: master is unqueued, this is deprecated But I don't need to enable earlyprintk to get serial output. BTW, this is not limited to mx31pdk_3ds, but it also do it on mx31moboard. It looks like it's related to the mc13783 PMIC, because the board *poweroff* itself. Maybe it's a bug in the regmap work of the mc13783 ? Regards, Philippe
