Re: [U-Boot] Delay in U-boot Booting , Running U-boot from NOR Flash
Hi Wolfgang,
I have given boot delay 3 seconds but this delay is for autobooting , my problem is not able to see u-boot booting messages ( console messages) on Minicom or Kermit as soon as power is up. Its should take less than 500ms to print console messages when u-boot boots up as far I know.
About booting from NOR Flash, I thought there may be an issue in DDR2 (SDRAM) initialization and relocating which is taking more time.
Sorry for sending locked or HTML messages last time.
Please need comments on this delay in u-boot messages printing on console. what may be the issue?
Regards,
Gurumurthy

Right. Messages should appear after a few milliseconds when booting from NOR.

U-Boot will start printing messages long before it starts accessing the RAM.

Misconfiguration of your hardware / port? Eventually you are running at an extremely slow clock rate?
