Data Abort on mapped address

li ruiming

Hi,

When I debug a LPC2103 program on MDK 3.22a, it always prompt me Data Abort error:

Data Abort: ARM Instruction at 00000428H, Memory Access at E0068020H

E0068020H is SSPICR register in LPC2103, and I had mapped this address in my ini file, like below:

/*Fast GPIO*/
MAP 0x3FFFC000,0x3FFFC01F READ WRITE
/*SPI*/
MAP 0xE0068000,0xE006802F READ WRITE

Note that accessing to 0x3FFFC000 has no error.

Please help me, thanks a lot!

    Hi,

    Thank you for response.

    I have resolved this problem by reselect the LPC2103 cpu in the Device dialog.

    I create this LPC2103 project in MDK 3.05 and recently upgraded to MDK 3.22a, it seems that MDK 3.05 doesn't map the GPIO and SSP, and when I upgrade, the map can't be upgrade automaticlly.
