  Hi,

I'm looking fwd to use an early printk for omap2 like it exists on other
architectures.

Did someone already released an early-printk patch?

Thanks.

Do you mean something other than low level printk?

Low level printk should work, see CONFIG_DEBUG_LL and
CONFIG_OMAP_LL_DEBUG_UART1 (or 2 or 3).

Seems like there has been some noise around some RT'ish changes + Timers
breaking some early printk's on the other lists.  I've not tried a build
recently to see if it affects OMAP at all.

Or it's a straight forward as CONFIG_DEBUG_LL.

Regards,
Richard W.

At least on OSK (OMAP1) CONFIG_DEBUG_LL works with recent 
git. Have no OMAP2 to test though.

CONFIG_DEBUG_LL doesn't work for me, have to debug.

Thanks all for your suggestions.

Just guessing, don't know OMAP2:

On OMAP1 we fixed [1] to get CONFIG_DEBUG_LL to work again. 
Maybe it's worth checking anything similiar on OMAP2, too?

What does "CONFIG_DEBUG_LL doesn't work for me" mean? No 
output at all?

Cheers

Dirk
