[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.
