So far, so good. I can boot a Linux kernel and RFS built by Buildroot under QEMU (versatilepb) where the RFS is exported via NFS. QEMU includes a boot loader, so U-Boot is not needed. But I use U-Boot with real ARM hardware, so I would like to experiment with U-Boot under QEMU, adding DHCP and TFTP to the mix. With real hardware, the U-Boot environment variables are persistent in flash memory. Is there a way to simulate this with QEMU? I would not go to the trouble to manually enter the U-Boot environment variables each time I boot under QEMU, but if there is a persistence mechanism available then including U-Boot might be practical. Thanks. Jim -------------- next part -------------- An HTML attachment was scrubbed... URL:
