Other Parts Discussed in Thread: Z-STACK

Hi ALL:

now I want to use the watch dog timer isr ,but when I add the watch dog timeout interrupt service and Compile error！

HAL_ISR_FUNCTION(halWatchDogIsr, WDT_VECTOR)
{
HAL_ENTER_ISR();
WDTIF = 0;
HAL_EXIT_ISR();
}

when I comment the above code and compile without errors

the IAR error:

Error[e16]: Segment CRC (size: 0x4 align: 0) is too long for segment definition. At least 0x4 more bytes needed. The problem occurred while processing the segment placement command
"-Z(CODE)CRC=0x0888-0x088B", where at the moment of placement the available memory ranges were "-none-"
Reserved ranges relevant to this placement:
CODE:800-88d INTVEC
BIT:0-7 BREG
BIT:80-87 SFR_AN
BIT:90-97 SFR_AN
BIT:a0-af SFR_AN
BIT:b8-c7 SFR_AN
BIT:d8-df SFR_AN
BIT:e8-ef SFR_AN
BIT:f8-ff SFR_AN
Error while running Linker

now I don't know how to solve this question!

I suppose you run out of flash and need to remove some application code to make it work.

Hi chen:
I don't think so,because I change it to the HAL_ISR_FUNCTION(halWatchDogIsr, ADC_VECTOR)
and compile OK!

HAL_ISR_FUNCTION(halWatchDogIsr, ADC_VECTOR)
{
HAL_ENTER_ISR();
WDTIF = 0;
//HalIndicationLedSet(HAL_IND_STATUS_LED, HAL_LED_MODE_TOGGLE);
HAL_EXIT_ISR();
}

I guess if the WDT_VECTOR have some question in the HA1.2.1 STACK?

Can you help me to have a try and add the HAL_ISR_FUNCTION(halWatchDogIsr, WDT_VECTOR)
in the HA1.2.1 stack? thank you!

Seeing as how the WDT is the last interrupt in the vector table (see ioCC2530.h) I would recommend that you make sure the proper memory is allocated in your f8w2530.xcl linker configuration. This issue does not seem to occur with Z-Stack 1.2.2a so you could perform a diff compare between the two stacks to observe any changes.

Ryan

Can you elaborate where you wnat me to put the following code in Z-Stack example code to verify it?
HAL_ISR_FUNCTION(halWatchDogIsr, WDT_VECTOR)
{
HAL_ENTER_ISR();
WDTIF = 0;
HAL_EXIT_ISR();
}

Hi chen:
if you have helped me to verify the HAL_ISR_FUNCTION(halWatchDogIsr, WDT_VECTOR),you can add this to the timer.c in the HA1.2.1 stack!

Hi Ryan:
I have turned on OTA function in the device ,so the memory is allocated in ota.xcl linker configuration,and I have not made any change in the ota.xcl!

Do you mean hal_timer.c?

Hi Ryan:
I find out a question in the ota.xcl:
-Z(CODE)INTVEC=_CODE_START

-Z(CODE)CRC=0x0888-0x088B
-Z(CODE)PREAMBLE=0x088C-0x0897

the WDT_VECTOR is defined in the ioCC2530.h:
#define WDT_VECTOR VECT( 17, 0x8B ) /* Watchdog Overflow in Timer Mode */

I guess if the CRC address overlap with the WDT_VECTOR address,If it is really like this,three is a bug in the HA1.2.1 STACK!

I suggest you reference the changes made in Z-Stack 1.2.2a and make sure that you are following the Z-Stack OTA Upgrade User's Guide.
