Hello,
 Does anyone has an application note or any example in which an hc08ap32  spi port is connected to an mmc/sd memory card.
Im trying but we have some troubles , the system works well in debug mode, but not alone.The spi signals are ok, and micro works fine.
 
Also when we connect the micro with the card together it does not work, (the supply pwer goes down)
but if you connect first the micro and then insert the card it works,
Any idea will be welcome.
thanks a lot.
