Thank you so much! Erase does not complain any more.
please do not top-quote on a mailing list.
However, write is not working.
Result is always something like: be040000: 00800080 00800080 00800080 00800080 ................
hm, I can't reproduce that:

and saveenv works for me too:

I enabled the debug info of both u-boot and qemu. I hope it helps. I am using master of qemu and u-boot, I get similar behavior in qemu since ever 1.5. Any clue?
I'm also using master of U-Boot and Qemu
