Hi guys,

I've been attempting to implement basic SPI flash in the mass sotrage example for 11Uxx in 0.98/a for a while, however find that whenever I include my flash file and call the setup function I get stuck in the following setup loop:

while (!(LPC_SYSCON->SYSPLLCLKUEN & 0x01)); /* Wait Until Updated */

What's making me lose my mind is that this loop should execute before any code as it's from system_LPC11UXX.c I don't have a clue how I got here. If I attempt to insert break-points it doesn't help, I get stuck here before I even reach the new code.

On the off chance this was a RAM space issue, I reduced a large memory structure in another file considerably to no avail, my new code doesn't use that much RAM so this seems unlikely...

I'm baffled guys, any idea?

You may have used software simulator instead of a hardware emulator. If so, you can add an initialization file with the content "map 0x40000000,0x400FFFFF read write".
