mangoH yellow ULPM

1

Hello,
tring to put mangoH yellow in ULPM.

Steps:

  1. sent AT!POWERWAKE=2,36,1
  2. AT!POWERMODE=3

on console i read:

[ 794.449680] swimcu_pm_wusrc_config: check statep->gpio_pin_mask 0x1
[ 799.463291] MCU Protocol Command 0xC2 failed, retry=11

[ 799.484429] swimcu_gpio_irq_event_handle: Re-enabled irq 0 type A for MCU GPIO 0

Nothing to do… no ULPM.

If i set sent AT!POWERWAKE=2,36,5 the device shutsdown:

but when i shake to restart… yellow light blink for a second and device wont boot… no output on console… if i continue to shake… same thing… yellow light… no boot.

Do i need additional steps?

didn’t you should trigger GPIO36 to wake up the module?

5

I guess the GPIO36 is connected to the INT1 of the BMI160. No?

6

have you checked if there is interrupt on GPIO36?

you can also see here for more information:

7

Nope… i dont have an oscilloscope here…
But… when i shake i see yellow light blink for a second…
See attached video…

8

I think INT1 is connected to GPIO38 according to schematic:

9

Yes… got same problem… but i need both interrupts active. I use gpio21 in software to handle movement alerts… and also i need INT1 to wake up when in ULPM.

…big problem…

10

Will try now with GPIO38… gimme some minutes…

11

Exact same behaviour with GPIO38. Led blinks… no boot.

12

how about trying the timeout value in AT!POWERWAKE?

Not sure if you need to trigger POWER_ON_N when module in ULPM mode, you can make some test on this pin

13

“how about trying the timeout value in AT!POWERWAKE?”

can you send me an example? I will try immediatly…

14

root@swi-mdm9x28-wp:~# microcom /dev/ttyAT
AT!POWERWAKE=2,38,5
OK
AT!POWERWAKE?
!POWERWAKE:
ULPM TIMER: 14400
PSM TIMER: 14400,ACTIVE TIMER:20,SYNC: 2
GPIO: 38, edge: 5, pull: 0

OK

15

you can try
at!powerwake=1,300
at!powermode=3

and see after 300 seconds, will it wake up?

16

Yes… it works. Using timer it wakeup.

Hi,
It looks like you are using WP7702 firmware version 12.
ULPM cannot be enabled with GPIO36/38. I had the same problem.

and no ULPM is activated…

How did you solved (Jeremy)?

21

didn’t you should use AT!POWERWAKE=2,38,5 from what you say above?
