Hi,

 

Is there any= specific reason why the (i.MX27) LCDC clocks are disabled in imxfb_probe()= (drivers\imx.c) ?

 = ;

#ifdef CONFIG_ARCH_IMX27

PCCR0 &=3D ~PCCR0= _LCDC_EN;

= #endif

 

I would have expected the clocks to be ena= bled in that routine.

&= nbsp;

I’m experimenting a li= ttle with Barebox’s ‘bmp’ command. Although the command d= id not return any error, I did not have any output on my lcd. Then I notice= d that the LCDC clocks were not enabled. If the clocks were not enabled by = default in the probe function, I would expect the enabling in the bmp comma= nd code, e.g. with FBIO_ENABLE ioctl command. But, as far as I can see, FBI= O_ENABLE is not executed in the bmp command code.

 

F= ilip
