hello, all:

   When I use qemu-system-arm to execute u-boot, I set the options with

   # qemu-system-arm -M versatilepb -pflash ramfs -kernel u-boot.bin -nographic

 

   And I enter the uboot successful, but when i execute plinfo command. I will get the bellow message

   Bank #1: missing or unknown FLASH type.

 

   I think the ramfs is wrong. So I hope somebody can show me how to build a simply ramfs. Thanks!

 

   My ramfs is built by "dd if=/dev/zero of=ramfs bs=1024 count=61556"

 

Best Regards!
