Hi everyone,

I'm currently trying to get Petalinux v0.30-rc1 to work on a
Spartan3E500 RevD
and now got stuck trying to make the flash available from within
Petalinux. The
flash works fine (used it a lot from u-boot), but when actually booting,
I get
the following output:

Then i can login normally, but the output of "cat proc/mtd" is

dev:    size   erasesize  name
mtd0: 00156000 00001000 "Romfs"

although there should be several flash partitions according to
menuconfig.

The only comment I found on that issue is that MTD might not be
configured
correctly, so here is my current configuration:

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

#

#
# CONFIG_MTD_ONENAND is not set

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

I followed the Spartan3E500 RevC tutorial carefully, the only exception
being
that I appended "root=/dev/mtdblock0" to the bootargs variable in u-boot
manually as the kernel wouldn't boot without it, and that the
clobstart-variable was 0x24000000.

Any help would be greatly appreciated, as I'm really stuck on this
one...

Thanks in advance and best regards

   Jakob
