Do you have an SD card in the system? I'm getting the same error when
accessing an SD card. Without SD card I can use the flash without any
errors.

No SD card in the system. At least not on my mx23evk board.
My real target hardware has a SDIO wifi chip.

Removing the SD didn't help here as well. Koen, which bootloader do you
use?
