I'm verifying my i.MX6DL custom board that running Android ICS(4.0.4).
I have some questions about the VDD_PU_CAP.
(1) I measured the VDD_PU_CAP. Sometimes, that was drop to approximately 0.2V. Is this correctly?
Operating range of the VDD_PU_CAP is between 1.15V and 1.225V according to the Datasheet (IMX6SDLCEC.pdf : Rev 5).
(2) It looks like overvoltage has occurred when it returns to the normal voltage. Is this cause the software?
(I attached two waveforms.)
