Hi

I looking for working vector.s file for Anglia Compiler

I've got the standard vectors.s, but it doesn't work with two interrupts (from VIC0 and VIC1)

Hi

Can you provide me with more details.

Did vectors.s works with only one interrupt?

regards

MBS,

Hi,

Maybe your problem will be the cause of nested interrupt.

also, I had same problem. would you modify the IRQ handler as following in the vect.s

IRQHandler

SUB lr,lr,#4 ;// Update the link register

SaveContext r0,r12 ;// Save the workspace plus the current

;// return address lr_irq and spsr_irq

LDR r0, = VectorAddress

LDR r0, [r0] ;// Read the routine address

;//LDR r1, = VectorAddressDaisy

;//LDR r1, [r1]

;// Padding between the acknowledge and re-enable of interrupts

;// For more details, please refer to the following URL

;//

http://www.arm.com/support/faqip/3682.html

;//NOP

;//NOP

;//MSR cpsr_c,#0x1F | I_Bit ;// Switch to SYS mode and disable IRQ modified by KMSHIM, 2007/03/15

;//MSR cpsr_c,#0x1F ;// Switch to SYS mode and enable IRQ

STMFD sp!,{lr} ;// Save the link register.

LDR lr, = IRQ_ReturnAddress ;// Read the return address.

BX r0 ;// Branch to the IRQ handler.

IRQ_ReturnAddress

LDMFD sp!,{lr} ;// Restore the link register.

;//MSR cpsr_c,#0xD2 | I_Bit ;// Switch to IRQ mode and disable IRQ

LDR r0, = VectorAddress ;// Write to the VectorAddress to clear the

STR r0,[r0] ;// respective interrupt in the internal interrupt

LDR r1, = VectorAddressDaisy ;// Write to the VectorAddressDaisy to clear the

STR r1,[r1] ;// respective interrupt in the internal interrupt

RestoreContext r0,r12 ;// Restore the context and return to the...

;// ...program execution.

good luck!!

best regards,

KMSHIM

Hi ,

Please find attached a project (RIDE/IAR/RVDK) with two interrupts and note that RIDE is using GNU compiler (GCC-ARM) so, you'll find the necessary modification needed to vector.s in 91x_init.s .

Regards,

MBS

I have two interrupts : one from TIM0 and one from UART0. When I use two interrupts I lose chars from UART0, but when I use ONLY TIM0 interrupts it works correctly

hi,

I didn't understand your question :( .

The example which i sent,is a solution to generate correct nested interrupt with VIC0 and VIC1 without any conflict .

did you try it?

MBS

Hi, MBS

Mode switch that you have done have been implemented in the IRQ handler.

I think that there are jsut differences as like nested interrut and writing to VICx->VAR.

Are there any difference in the your code?

Hi KM SHIM,

i think the problem of spurious interrupt are now solved with the different modifications that we have done on Vector.s and it.c .

have a look to IRQ project which i send previously.(waiting for your feedback 8-) )

Regards,

MBS

Hi GrzesiekFl,

Quote:

When I try to complie the project in Anglia IDE I receive the following warrings:

./../../library/inc/91x_it.h:44: warning: empty declaration

./../../library/inc/91x_it.h:45: warning: empty declaration

./../../library/inc/91x_it.h:66: warning: empty declaration

it was due to this:

Quote:

#ifdef __GNUC__ /* GCC Compiler */

#define interrupt __attribute__ ((interrupt));

#define irq interrupt

#endif

in fact,with an interrupt function the declaration should be as follow :

Quote:

void FOOxxxx (void) __attribute__ ((interrupt));

:o

the problem now is : why it works fine with RIDE compiler (which uses GCC-ARM) and doesn't with ANGLIA ? 8-)

I'm investigating ...

in meanwhile, please find attached the corrected project.

Best regards,

MBS

Hi MBS

When I try to complie the project in Anglia IDE I receive the following warrings:

In file included from ./../../library/inc/91x_vic.h:27,

from ../../library/src/91x_vic.c:21:

./../../library/inc/91x_it.h:45: warning: empty declaration

./../../library/inc/91x_it.h:66: warning: empty declaration

What's going wrong?

Regards. Greg

And when I try to compile project in Release Mode I receive errors:
