hi i m trying to access cp15 registers in data abort handler. I understand that to access cp15 registers u got to be in privileged mode, so as im in data abort handler the mrc instruction should work. But as i do compiler shows following error...



58 0000008c MRC p15, #0, r1, c0, c0, #0 "/vobs/global/esf/bsp/boot/armthumb/regDump.s", line 61: Error: A1152E: Unexpected operator 61 00000090 MRC p15, #0, r1, c0, c0, #1 "/vobs/global/esf/bsp/boot/armthumb/regDump.s", line 64: Error: A1152E: Unexpected operator 64 00000094 MRC p15, #0, r1, c0, c0, #2 "/vobs/global/esf/bsp/boot/armthumb/regDump.s", line 67: Error: A1152E: Unexpected operator 67 00000098

for all the registers access using MRC instruction.. I am not able to figure out the problem...anybody can help me out?



thanks girish

It seems you are not using the syntax that your assembler requires.

Try dropping the '#'. Make sure you have the right value for opcode_2.
