We designed a carrier board for the CM and we noticed that the CM boots raspbian after few minutes.
We checked all the power supplies, power sequencing, RUN signal state...
Our schematic is very similar to the CMIO board about the EMMC_DISABLE_N and USB flashing circuitry.
However all the GPIOs are used in our design and we are wondering if some GPIOs are latched on reset and which could modify the boot sequence.
Can you put a video on dropbox? Do you actually mean minutes?
Have you tried changing the state of the eMMC enable bit? Does it go into USB booting mode? (This will normally take an extra 5 seconds)
