Hi Andrew Kinmont,
Thanks for your updated information.
I have checked MIMXRT1051CVL5B, I didn't find any special points about the wakeup pin with RT1052.
Do you also use the SDK code? Because the wakeup pin need to do the pin configuration.
Now, even you use the official code, you still can't make the wakeup pin works? Could you try to add an external pull up in the wakeup pin , then test it again?
Any updated information, please kindly let me know.
Have a great day,
Kerry

Hi Andrew Kinmont,
Sorry for my later reply.
Today, I test your held SW8 function on my MIMXRT1050-EVKB board, but I didn't reproduce your problems.
Code: SDK_2.6.1_EVKB-IMXRT1050\boards\evkbimxrt1050\demo_apps\power_mode_switch_bm
I do it follow the following steps:
1. reset the board, printf the information.
2. press the SW8 and hold on it.
3. Input "H", to enter the SNVS mode
4. release the SW8 switch
You can find when I release the SW8 button, the chip will be waked up automatically, you even don't need to press it again.
I suggest you also test it like me, associated with the power consumption and the printf information to test it.
Even from the power consumption, you also can find when you release the SW8, the chip already be waked up.
I have tested it for a lot of times on my MIMXRT1050-EVKB, it also works.
About the RT1051 chip, I still didn't get the sample, maybe need more time.
Have a great day,
Kerry

Hi Andrew Kinmont,
I have tested the MIMXRT1051CVL5B SNVS mode wake up function, totally with the SDK code:
SDK_2.6.1_EVKB-IMXRT1050\boards\evkbimxrt1050\demo_apps\power_mode_switch_bm
The same test result with MIMXRT1052, so the chip should doesn't have any difference.
My test chip is:
MIMXRT1051CVL5B
1N04V
CTAU1849A
This is the test result:
So, maybe still need to check the hardware side. I can make sure the RT1051 is the same as RT1052 about the SNVS wakeup module.
Best Regards,
Kerry
