µVision3 - LPC2103 - Fast IOs

Bernd M

Hi,

just wanted to test a simple program, that accesses the new Fast IOs of the LPC2101/2/3 series from Philips.

But whenever a new register (addresses right below the lowers RAM address) is accessed, I get the message "*** error 65: access violation at 0x3FFFC01C : no 'write".

I already found the hint to write an .ini file and add it to the debugger.

.ini file content:

MAP  0x3FFFC000, 0x40000000  READ WRITE  // allow R/W access to IO
space

The debugger does display the MAP command on startup, but the address is still invalid.

But when I copy the MAP command line and enter it manually, when µVision is already in debug mode, the MAP command works as expected and the "*** error 65: access violation at 0x3FFFC01C : no 'write" message disappears.

Thanks,
Bernd
