Hi,
I am using MQX4.1 on a K70 (part of our product).
We have been working on getting our product updated from MQX4.0.2 on and off for a while now, and I only have a few issues remaining.
One of the things I have been struggling with is getting the unit to wake from VLLS3.
Here is the configuration:
At the point we go to sleep we are running from the internal reference oscillator, with OSC0 configured but not used:
MCG_C1 0x44
MCG_C2 0x27
MCG_C3 0x45
MCG_C4 0x14
MCG_C5 0x0
MCG_C6 0x0
MCG_S 0x17
MCG_SC 0x2
MCG_ATCVH 0x0
MCG_ATCVL 0x0
MCG_C7 0x1
MCG_C8 0x0
MCG_C10 0x0
MCG_C11 0x0
MCG_C12 0x0
MCG_S2 0x0
OSC0_CR 0xA0
Cannot access memory at address 0x400e5000
OSC1_CR 0x
(OSC1 is not accessible because it is not clocked)
SIM_SOPT1 0x80089010
SIM_SOPT1CFG 0x0
SIM_SOPT2 0x40471004
SIM_SOPT4 0x0
SIM_SOPT5 0x7F7F7F00
SIM_SOPT6 0x0
SIM_SOPT7 0x0
SIM_SDID 0x31DE
SIM_SCGC1 0x800
SIM_SCGC2 0x0
SIM_SCGC3 0xB425010
SIM_SCGC4 0xF00430B0
SIM_SCGC5 0x47F8F
SIM_SCGC6 0x78440007
SIM_SCGC7 0x7
SIM_CLKDIV1 0x13770000
SIM_CLKDIV2 0x2
SIM_FCFG1 0xD000F00
SIM_FCFG2 0x20A00000
SIM_UIDH 0x320000
SIM_UIDMH 0x29C67801
SIM_UIDML 0x4E452589
SIM_UIDL 0x200F001A
SIM_CLKDIV3 0x0
SIM_CLKDIV4 0x0
SIM_MCR 0x10024
before we try to go to sleep we set the deepsleep functionality:
SCB_SCR = SCB_SCR_SLEEPDEEP_MASK | SCB_SCR_SLEEPONEXIT_MASK;
and we configure the SMC:
SMC_PMPROT 0x2A
SMC_PMCTRL 0x4
SMC_VLLSCTRL 0x3
SMC_PMSTAT 0x1
The LLWU module is configure to wake up on RTC alarm, several port pins, or on reset pin:
LLWU_PE1 0x0
LLWU_PE2 0xFC
LLWU_PE3 0x3F
LLWU_PE4 0x0
LLWU_ME 0x60
LLWU_F1 0x0
LLWU_F2 0x0
LLWU_F3 0x0
LLWU_FILT1 0x0
LLWU_FILT2 0x0
LLWU_RST 0x2
The unit seems to 'stop', but doesn't wake up again.
This used to work in MQX4.0.2, so I am assuming I have missed some register or peripheral that needs clocking. Any assistance would be greatly appreciated, I have been struggling with this one for a full week now.
Thanks
Chris
