Hello!
We are research group at the EPFL(Swiss Institute of Technology). We
are using Altera EPXA1 board with two flash memory types: ST M58LW064D
and INTEL TE28F640J3C120. We are using our flasher that is developed
in our lab and we can program both flashes with RedBoot. But after
that we can't further program the flash (with file system and kernel)
nither by our flasher nor by RedBoot. We got these messages from
redboot(that is installed and run from the flash!):
uBoot via JTAG - Version 1.0

******************
As you can see there is some 'configuration checksum error or invalid
key' that results in that we can't errase or program the flash later.
The strange thing is that we already have redboot in the flash!
Thanks in advance for any kind of help
