ive only used the arm on the leaflabs maple
and that programs using the arduino interface
but i did use the spi port

what platform are you using
and what problems are you hitting

Not sure :\ but i am doing it on a STM32F407VGT6 i think i can get around 10MB/s if the flash is that fast . I don't know how to calculate it though . 100MHz Flash . Don't know about the speeds .
