RPi_Baremetal

What's this?

This is a respository of my Raspberry Pi Baremetal Experiments

Contets

• sdcard_gpio_spi: demo of accessing sdcard through gpio in SPI mode

• sdcard_gpio_bus: demo of accessing sdcard through gpio in bus mode (standard mode)

Running the demo

• Prepare a sd card that holds raspbian OS and you don't need any more (Contents of the card may be destroyed by this demo. So, make sure to use a one that you can waste.)

• replace kernel.img in your raspberry pi boot sd card with the kernel.img here, and start raspberry pi

• You need UART connection to GPIO ports #14 and #15
