CC2538 ZStack POWER_SAVING issues

DanO,
Can you please clarify the stack version you are using?

In your use case, assuming the CC2538 entered a low power mode, what would wake up the CPU. Typically this would be an Osal timer or a poll timer for PM 1/2. If you enable a 5s timer in the application that should suffice for debug purposes. Can you put a break point on HAL_SLEEP_SET_POWER_MODE in hal_sleep.c and verify if this is being hit.

Regards,
TC.

Hi TopCat, Thanks for your response,
It is ZStack Energy 1.1.0, IAR 7.20.1.
Its end of the day here, Ill do the timer and breakpoint tomorrow.

Thanks again, DanO.

Ok thanks, I am also setting up the same test with 1.1.0.

Hi TopCat,

I have done the test as you suggested. In an attempt to make it a more straight-forward ZStack power-saving scenario, I did change some of the parameters of the test to something more simple:

1. As before, enable POWER_SAVING in the defined symbols.

2. Re-enable NWK_AUTO_POLL in the defined symbols.

3. In f8wconfig.cfg, back to defaults: -DRFD_RCVC_ALWAYS_ON=FALSE ; -DPOLL_RATE=1000 ; -DQUEUED_POLL_RATE=100 ; -DRESPONSE_POLL_RATE=100.

4. As before, set all unused IO to outputs, no connections.

5. As before, cancelled the time update event called IPD_UPDATE_TIME_EVT, but had the timer-test event active.

6. As before, disabled HAL_KEY.

Even with the simpler scenario, the breakpoint at HAL_SLEEP_SET_POWER_MODE () does NOT trigger. So something must be wrong.

Any suggestions are welcome, thanks again for your time.

Regards, DanO.

I forgot to add:

Whilst the test is running, when I push the "break" button under the debug controls, the execution is on the MAC_RADIO_TIMER_SLEEP(); line in mac_sleep.c. When I push "go", and "break" again, the execution is still there.

I tried disabling POWER_SAVING again, and everything works fine( Interrupts, test-timer event, etc)

Something else I forgot to add: I disabled as many of the defined symbols as I could, as I thought that they were not necessary and might add to the power consumption. Perhaps I "broke" the code by doing this?! Here is the list of pre-defined symbols for my test:

DANIEL_PCT_CI_SE_2013 (Personal addition)
POWER_SAVING
REMOTE_CONTROL_IT (Personal addition)
HAL_LED
ZCL_REPORT
xHAL_KEY
xOSALMEM_METRICS
xLCD_SUPPORTED
ewarm
ZCL_KEY_ESTABLISH
TC_LINKKEY_JOIN
NWK_AUTO_POLL
NV_INIT
xNV_RESTORE
xZTOOL_P1
xMT_TASK
xMT_APP_FUNC
xMT_SYS_FUNC
xMT_ZDO_FUNC
INTER_PAN
HOLD_AUTO_START
xTEST_CERT_DATA
xMT_SYS_KEY_MANAGEMENT
CC2538_USE_ALTERNATE_INTERRUPT_MAP=1

I hope that this helps, thanks again.
Rgds, DanO

Hi TopCat (and any other readers),

It seems I have solved most of the problem:

Firstly, being an IPD, there were default price-update timers running that I did not know about. What would happen is that it would go into some low power mode and then after 5s it would service the timer and not go back into low power mode. Anyway after disabling the timer it seemed to wait a bit at 10mA consumption, and then eventually drop significantly to the low 10s of uA.

Secondly, I didn't read the CC2538 power document properly and missed the bit about changing OnboardKeyIntEnable to HAL_KEY_INTERRUPT_ENABLE, although in this case I had HAL_KEY disbaled, so it wouldnt have made a difference, but someone else reading this might find that changing these setting will help them.

Thirdly, also being an IPD, the default setting for ipdPowerSource was the default "POWER_SOURCE_MAINS_1_PHASE", so I changed it to POWER_SOURCE_BATTERY. Not sure if this was needed to make it work, but there seemed to be ares of the power-saving manager that checked for this. This setting is found under ipd_data.c


But, I still have one more issue:

Once in sleep-mode, it will not wake up for any state changes on PortC or Port D. I have tried to make use of GPIOPowIntTypeSet(), GPIOPowIntDisable(), GPIOPowIntEnable(), GPIOPowIntClear. These are found in hal_sys_crtl.c and I have tried to use these functions in the same way that the file has them set up for the board buttons, see the code below ( "REMOTE_CONTROL_IT " is my project name):

#if defined ( REMOTE_CONTROL_IT )
GPIOPowIntTypeSet(GPIO_C_BASE, ( GPIO_PIN_0 | GPIO_PIN_1 | GPIO_PIN_2 | GPIO_PIN_3 |
GPIO_PIN_4 | GPIO_PIN_5 | GPIO_PIN_6 | GPIO_PIN_7 ), GPIO_POW_FALLING_EDGE );
GPIOPowIntTypeSet( GPIO_D_BASE, GPIO_PIN_2, GPIO_POW_FALLING_EDGE);
#else //REMOTE_CONTROL_IT
/* Setup GPIO A, C as a falling edge */
GPIOPowIntTypeSet(BSP_KEY_DIR_BASE, BSP_KEY_LEFT | BSP_KEY_RIGHT |
BSP_KEY_UP | BSP_KEY_DOWN, GPIO_POW_FALLING_EDGE);
GPIOPowIntTypeSet(BSP_KEY_SEL_BASE, BSP_KEY_SELECT, GPIO_POW_FALLING_EDGE);
#endif //REMOTE_CONTROL_IT

#if defined ( REMOTE_CONTROL_IT )

}

GPIOPowIntDisable( GPIO_D_BASE, GPIO_PIN_2 );
#else //REMOTE_CONTROL_IT
GPIOPowIntDisable(BSP_KEY_DIR_BASE, BSP_KEY_LEFT | BSP_KEY_RIGHT | BSP_KEY_UP |
BSP_KEY_DOWN);
GPIOPowIntDisable(BSP_KEY_SEL_BASE, BSP_KEY_SELECT);
#endif //REMOTE_CONTROL_IT

void SysCtrlPowIntClear(void)
{
#if defined ( REMOTE_CONTROL_IT )
GPIOPowIntClear(GPIO_C_BASE, ( GPIO_PIN_0 | GPIO_PIN_1 | GPIO_PIN_2 | GPIO_PIN_3 |
GPIO_PIN_4 | GPIO_PIN_5 | GPIO_PIN_6 | GPIO_PIN_7 ) );
GPIOPowIntClear( GPIO_D_BASE, GPIO_PIN_2 );
#else //REMOTE_CONTROL_IT

#endif //REMOTE_CONTROL_IT
}

Any advice would be highly valued! Thanks for your time in reading all this.

Hi TC,

Ok thanks for the suggestions. I have been attempting to change HAL_KEY.c all of today actually. I've almost got it to work, but there is a little problem, perhaps you could help? ...

I have tried to replicate the code to suit 8 inputs instead of 4, such that all 8 of port C's IO is used. When I test it, only the original button-designated IO of port C trigger the interrupt system. I do not use the SmartRF06EB's buttons, I have used the various breakout headers with bridging wires, etc, to simulate my scenario.

It seems like the other IO have not been registered to interrupt. So, the problem seems to be with the function called
bspKeyIntEnable( BSP_KEY_ALL );

I changed BSP_KEY_ALL as follows ...

#define BSP_KEY_ALL ( BSP_KEY_1| \
BSP_KEY_2| \
BSP_KEY_3| \
BSP_KEY_4| \
BSP_KEY_5| \
BSP_KEY_6| \
BSP_KEY_7| \
BSP_KEY_8 ) //!< Bitmask of all keys

I defined each BSP_KEY_x as ...

#define BSP_KEY_DIR_BASE GPIO_C_BASE //!< Base for keys
#define BSP_KEY_SEL_BASE GPIO_D_BASE //!< Base for Select (Mode)
#define BSP_KEY_1 GPIO_PIN_0 //!< PC0
#define BSP_KEY_2 GPIO_PIN_1 //!< PC1
#define BSP_KEY_3 GPIO_PIN_2 //!< PC2
#define BSP_KEY_4 GPIO_PIN_3 //!< PC3
#define BSP_KEY_5 GPIO_PIN_4 //!< PA4
#define BSP_KEY_6 GPIO_PIN_5 //!< PC5
#define BSP_KEY_7 GPIO_PIN_6 //!< PC6
#define BSP_KEY_8 GPIO_PIN_7 //!< PC7

All of these original defines are found in bsp.h

I cannot find the function code for bspKeyIntEnable(...), I assume that its in a library file, perhaps you know which one?

Any suggestions are welcome. Thanks again for your time.

Regards, DanO.
