Hello,

I am new to the assembly code. The code which I given below is compile(assembling) fine in KEIL.

AREA |.text|, CODE, READONLY

EXPORT vF_dspl_pid

vF_dspl_pid
push {r4-r7}

ldrsh Kp,[pS_StateCoeff]
ldrsh Ki,[pS_StateCoeff,#2]
ldrsh Kd,[pS_StateCoeff,#4]
ldrsh IntegratedError,[pS_StateCoeff,#6]

mla Acc,Ki,si_Error,IntegratedError //update integrated error
strh Acc,[pS_StateCoeff,#6] //store to state

ldrsh LastError,[pS_StateCoeff,#8]
strh si_Error,[pS_StateCoeff,#8]

mla Acc,Kp,si_Error,Acc //add in proportional part

sub Temp,si_Error,LastError
mla Acc,Kd,Temp,Acc //add in the difference part

mov Acc,Acc,ASR#16 //scale down to short int
pop {r4-r7}
bx lr

END

But when I switch from KEIL to ROWLEY CROSS WORKS. The foolowing errors are getting during assembling.

Error: bad instruction 'area |.text|,CODE,READONLY'

Error: bad instruction 'export vF_dspl_pid'

Error: bad instruction 'vf_dspl_pid'

Error: Thumb does not support this addressing mode -- 'ldrsh r3,[r1]'

Error: Thumb does not support this addressing mode -- 'ldrsh r4,[r1,#2]'

Error: Thumb does not support this addressing mode -- 'ldrsh r5,[r1,#4]'

Error: Thumb does not support this addressing mode -- 'ldrsh r6,[r1,#6]'

Error: Thumb does not support this addressing mode -- 'ldrsh r6,[r1,#8]'

Error: shifts in CMP/MOV instructions are only supported in unified syntax -- 'mov r7,r7,ASR#16'

Error: bad instruction 'end'
Build failed

Kindly give me suggession to get out of these errors. Start a New Thread

Go back to Keil

Just off the top of my head...Read the GCC/AS documentation - find
example assembly files to copy - set up your build options for the
mode/cpu you are trying to compile for.

Or better: Read both manuals (hint: label syntax, assembler directives).

You're absolutely correct..."If all else fails! Read the manual! That is what most people do when they use something that is new to them."
