Other Parts Discussed in Thread: TPS65217
Hello,
We are doing a design with a AM3358 processor but we are not using a TPS65217, we are using LDOs instead. The thing is that I recently started reading the datasheet (I wasn't part of the design initially) and I noticed that the beaglebone black is heavily dependant around the TPS part and I noticed that there is also a lot of code on the kernel that links directly to the TPS, and there's also the fact that there is a power supply sequencing (datasheet Figure 6-4), which is simply not followed the LDOs we're using (also all the pins related to the TPS in the BBB schematic are also not used .. PMIC_POWER_EN, PWR_BUT, I2c0, PMIC_GOOD, LDO_GOOD, WAKEUP, PMIC_INT).
The schematic and everything I've been reading leads me to believe that this board we are developing will not even boot when powered on. Is this right? Can I just put some delay after RTC_PWRONRSTn to simulate the necessary 1ms assertion before releasing reset?
