Today I reconnected the PiCamera to my BrickPi, which required disconnecting the BrickPi in order to connect the camera to the raspberry pi.
I’ve tested the camera with the raspberry alone (BrickPi disconnected) and with power via the mini usb (using an official Raspberry Pi Universal Power Supply) and it worked well.
after shutting down the raspberry, i reconnected the BrickPi and reassembled the cover.
now when i use the BrickPi power socket no light comes, and when I’m using the USB a red light shows.
I know that red light on a raspberry means I’ll have to wait 25 hours and retry or just format the SD card, but I’m more intrigued about why no power comes from the BrickPi to the raspberry pi when using the BrickPi’s power socket.
also, any idea how to fix the card without a card reader (using a cellphone with a microSD slot for example) would be appreciated.
