To do this, you will need to copy all of the files from a Raspberry Pi boot partition plus create your own The RPIBOOT protocol provides a virtual file-system to the Raspberry Pi bootloader and GPU firmware. ** The secure-boot-msd, rpi-imager-embedded and mass-storage-gadget extensions require that the (or newer) bootloader EEPROM release has already been written to the EEPROM using recovery.bin ** Booting Linux Scripts for signing the MSD firmware so that it can be used on a secure-boot device
Scripts that extend the recovery process to enable secure-boot, sign images etc
#Jp4 mass storage device driver drivers#
Uses Linux USB gadgetfs drivers to export all block devices (e.g. Runs the embedded version of Raspberry Pi Imager on the target device Updates the bootloader EEPROM on a Compute Module 4 In addition to the MSD functionality, there are a number of other utilities that can be loaded Otherwise, the SPI EEPROM bootloader image will be loaded instead. On Compute Module 4 EMMC-DISABLE / nRPIBOOT (GPIO 40) must be fitted to switch the ROM to usbboot mode. Make sure that the system date is set correctly, otherwise Git may produce an error.įit the EMMC-DISABLE jumper on the Compute Module IO board before powering on the board
The firmware in the msd can be replaced with newer/older versions.įor more information run rpiboot -h Building Linux / Cygwin / WSLĬlone this on your Pi or a Linux machine. Where the firmware should be loaded from.Į.g. Other versions of the firmware by passing the -d flag to specify the directory Since RPIBOOT is a generic firmware loading interface it is possible to load If the storage has not been formatted yet (default for Compute Module) Will treat this as a normal USB mass storage device allowing the file-system Special firmware so that it emulates USB Mass Storage Device (MSD). The default behaviour when run with no arguments is to boot the Raspberry Pi with Module 3, Compute Module 4 and Raspberry Pi Zero. This is the USB MSD boot code which should work on the Raspberry Pi model A, Compute Module, Compute
