Is it possible to enter RTC-Only power mode as per section 220.127.116.11.5 in AM335x TRM? BeagleBone Black Board is using TPS65217C, which, according to Paragraph 1 in slvu551i, does not support this operation, however, it is not clear why TPS65217A/B support this mode, and C/D do not. Then there is this official table from TI, which, in contrast, states that all TPS65217x support RTC-Only operation. Unfortunately, there seem to be no conclusive answers on TI forums. Can someone please help clarify this?
