Problem downloading U-boot via UART Downloader with OMAP35xEVM

I made a mistake.

Before the operation downloading U-boot via UART Downloader, I changed U-boot option like this:

--------------------------------------------

setenv get_kernel run nand_kernel

setenv get_initrd run nand_initrd

setenv bootcmd run boot_fs

saveenv

--------------------------------------------

As a result, i can't get a U-boot prompt when finishing download.

The Linux kernel became to auto booting every time.

How can i restore the U-boot prompt?

Thank you in advance.

Chapter 5 of the Getting Started Guide has instructions on reflashing u-boot.

If the situation is just that your bootdelay environment variable got cleared or set to 0 than you can interrupt U-Boot by pressing ctrl-c, but this has to happen before it actually starts the kernel, this way you should be able to get into U-Boot without having to go through the reflash procedure (though that should also work).
