Hi, The BB itself has its HDMI disabled, thus I assume there's no conflicting pins when using the cape. The cape itself utilizes P8_01, P8_02, P8_27 until P8_34 and P9_01, P9_02, and P9_21 until P9_28. The cape gets its power not from the power adapter from the BB but from another power supply, thus it doesn't absorb power from the BB at all. But even with having the cape unpowered, the BB still cant finish booting the kernel. If it somehow adjusting boot mode, which pin number that (if any being used by the cape) is being used by the BB for kernel booting?
