Playground of RaspberryPi baremetal (V3D, HDMI Audio, DMA, DWC2 USBHost, UART, Framebuffer)

Playground of RaspberryPi baremetal.

What is a baremetal?

The baremetal means not using linux or some OS. Build with scratch to alls. One of the exception I believe VideoCore4 has such an OS on firmware or something.

Requirement

• Raspberry Pi Zero W or such devices.
• Ubuntu (latest)
• Arm compiler sudo apt install gcc-arm-none-eabi

raspberrypi's Issues

Undefined instruction occuring when using DMA transfer with usin HDMI audio.

proc

1. checkout c9e5794
2. Move to Sample_HDMI_DMA_Audio_Streaming_01
3. Run ./allmake.sh on su and copy kernel.image to sdcard
4. Insert SD card to RPIZEROW and turnon
5. wait the 2.0h and obse the tty
6. problem occuring literally
