[En-Nut-Discussion] Flashing Ethernut3 with OpenOCD

[Andrej Taran]

Hi,
I try to flashing the AT49BV322 with OpenOCD rev. 204.
Commands 'flash probe 0' and 'flash info 0' work.
But command 'flash erase 0 0 70' chip not erased.
It output
 > flash erase 0 0 70
erased sectors 0 through 70 on flash bank 0 in 2s 359375us

Has someone to work with OpenOCD and the Ethernut3 board?
