Re: AM335x, early printk
Hi! You need to add 'earlyprintk' in the kernel command line, given (I suppose) by U-Boot. I hope this helps!

AM335x, early printk
Hi, I activated: [*] Kernel low-level debugging functions Kernel low-level debugging port (Kernel low-level debugging messages via OMAP2PLUS UART) Low-level debug console UART (AM33XX UART1) [*] Early printk and booted my am335x-evm. I haven't seen any "early" output in the decompressor or during the kernel boot. I believe that all I saw is just regular ttyO0 output. I saw also: |44e09000.serial: ttyO0 at MMIO 0x44e09000 (irq = 88) is a OMAP UART0 |console [ttyO0] enabled and I would also except the bootconsole (if any) to be deactivated here. What am I missing?
