hi all, i'm currently working on USB host controller driver on lpc2468. i'm trying to simulate the driver with keil. after initialization of usb clock, i'm checking if device is connected on port or not. when program counter points to status register, data abort condition occurs.
similarly, after usb clock initialization if i try to access any register like HC_HCCA, in USB controller data abort condition occurs.
i came across same condition when i was trying to simulate usb-audio source code (which i downloaded from keil website).
currently i don't have u-link debugger. does any one how to deal with this problem.
