[U-Boot-Users] u-boot dos not autostart commands
Hi all. I have PXA270 board with embedded by vendor bootleader - "U-Boot 1.3.0". I define that environment: --- $ printenv baudrate=115200 bootdelay=3 bootargs=video=pxafb:mode:800x480-16,active,pixclock:37000,left:100,right:1,hsynclen:10,upper:20,lower:1,vsynclen:10,outputen:1,pixclockpol:0 root=/dev/sda1 rootdelay=20 console=ttyS0,115200 bootcmd=cp.b 01e00000 a1000000 13216e stdin=serial stdout=serial stderr=serial
Environment size: 298/262140 bytes --- But after power on, I cannot see countdown & run bootcmd. If I 'run bootcmd' by hand - that works OK. But not automatically after power on. Can anybody tell me, how I can solve this ?
Thank you.

It seems that support for bootdelay (CONFIG_BOOTDELAY) is not enabled in your vendors version of U-Boot. So to get this feature you will have to compile a new U-Boot.

bootcmd=cp.b 01e00000 a1000000 13216e

Simple test autostart. If I run it manually, this copy linux uImage from FLASH to RAM..

Thank you, I will ask them.

You know "bootm" will do this for you?

I know, but u-boot do _NOTHING_ after power on. Any command in 'bootcmd' is ignored.

Probably that was not selected in the board configuration?

Add at least CONFIG_BOOTDELAY to your board configuration, build and install the new version.
