Our BBBw customized board cannot wake up from sleep. I tried RTC, UART0, PWR_BUT methods. They are working on the BBBw but not on our production boards ( both are tested under the same version of the kernel). Although this is beyond your scope of support, I would appreciate if you have any suggestions that may hint to the hardware design with your knowledge and expertise in the Linux. I am software myself, I believe it has something to do with the PMIC, that power management chip. Just wondering there is any special consideration for waking up from the sleep state of BBBw.
Thank you very much,
