Re: Is CM3 compatbile with the CM1 development board?

Now I have received my 2nd new CM3 module (with eMMC) and I have tried to boot it on my CMIO V1.2 board. I handle jumper J4 as for my two working CM1 modules. Flashing (Win32DiskImager) with Jessie Lite (2017-01-11) is possible (both CM3s). VBAT changed to 5V as specified. Both CM1 modules are worki...

Re: Is CM3 compatbile with the CM1 development board?

Question:

For a first draft test after flashing a lite image version into the eMMC (CM3) I do not need to change the VBAT to 5V on a CMIO V1.2 board?

My current state is: Flashing has worked, but after changing J4 back CM3 doesn't boot :-(
