After doing some more testing I’ve found that using ADC1 and ADC2 work just fine as boot sources. I’m still having issues getting GPIO 36 or 38 to work however.
If I use the pmtool to setup a GPIO boot source via:
pmtool bootOn 36 low
I get the following error:
Bad boot source: 36
I also looking into which GPIOs are setup using the following AT command:
As you can see pin 36 and 38 aren’t setup as GPIOs. I’m not sure if they should or should not be, just some additional information. It also may help to know I’m using a
WP7603 as my module currently.
