Yeah I wasn't far away but word to the wise, copy part for part the power management from the CMIO board! It will save a headache in futureSpringy wrote:Yup, keep at it! Doesn't sound like you were far away from it
oooh thats good to know , also is there anything i need to check and make sure with the layout/ schematic or have I covered pretty much most of it?You can get rid of the crystal
Beat me to it , was going to say that, but the next thing is how have you connected GPIO47? I know that you want to keep your schematic secret but are you able to display the schematic on how you have done the EMMC_DISABLE_N section?How about EMMC_DISABLE_N?
Oh yes the hardest part about this that i had to learn on the fly was getting the USB and Ethernet to meet specifications once that was done, everything else was easy.USB2 spec calls for 5v +/- 0.25v officially so technically you are still within the specifications.
