…description is wrong, so you might be eligable for a refund or you just keep it and get another one. its an excellent price for the f429 btw., but unfortunately mios is not ported (yet) for that board, as discussed before…
alternatively, for that price you could do all of us a favour and send it to tk 4free!
The dealer sent me immediately the correct board and i could retain the other one.
If anyone is interested in the STM32F429I-DISCO board
i would trade it against a PIC18F4685 with bootloader.
