Method for starting-up a device with an embedded multimedia card (eMMC)

1. A method for starting-up a device with an embedded multimedia card (eMMC), comprising:

providing power to the device;

putting the eMMC in a Fast-Boot modus for a first duration;

reading a bootloader from the eMMC from a first boot area into a Random-Access Memory (RAM) of the device during the Fast-Boot modus for the first duration of the eMMC;

starting the bootloader in a CPU of the device;

terminating the Fast-Boot modus after the first duration in response to starting the bootloader;

resetting the eMMC after the terminating;

putting the eMMC in the Fast-Boot modus for a second duration after the resetting the eMMC;

initializing hardware by the bootloader, while reading an operating system into the RAM from a second boot area and/or a main data area using Direct Memory Access (DMA); and

starting the operating system from the RAM by the bootloader.

2. The method according to claim 1 , wherein providing power to the device, putting the eMMC in a Fast-Boot modus for a first duration, reading the bootloader from the eMMC from a first boot area into the RAM of the device during the Fast-Boot modus for the first duration of the eMMC, starting the bootloader in the CPU of the device and/or terminating the Fast-Boot modus after the first duration in response to starting the bootloader are carried out by a ROM Code.

3. The method according to claim 1 , wherein resetting the eMMC after the terminating and/or putting the eMMC in the Fast-Boot modus for a second duration after the resetting the eMMC are carried out by the bootloader.

4. The method according to claim 1 , wherein in initializing hardware by the bootloader, while reading an operating into the RAM from a second boot area and/or a main data area using DMA, the bootloader instructs an eMMC Controller to read the operating system into the RAM using DMA.

5. A device, comprising:

an embedded multimedia card (eMMC); and

a memory,

wherein a set of controller executable code is stored in the memory, and the set of controller executable code is executed by an eMMC controller to perform operations comprising:

providing power to the device;

putting the eMMC in a Fast-Boot modus for a first duration;

reading a bootloader from the eMMC from a first boot area into the memory of the device during the Fast-Boot for the first duration of the eMMC;

starting the bootloader in a CPU of the device;

terminating the Fast-Boot modus after the first duration in response to starting the bootloader;

resetting the eMMC after the terminating;

putting the eMMC in the Fast-Boot modus for a second duration after the resetting the eMMC;

initializing hardware by the bootloader, while reading an operating system into the memory from a second boot area and/or a main data area using Direct Memory Access (DMA); and

starting the operating system from the memory by the bootloader.

6. The device according to claim 5 , wherein the device is a navigation device or an infotainment device.

7. A device installed in a vehicle, the device comprising:

an embedded multimedia card (eMMC); and

a memory,

wherein a set of controller executable code is stored in the memory, and the set of controller executable code is executed by an eMMC controller to perform operations comprising:

providing power to the device;

putting the eMMC in a Fast-Boot modus for a first duration;

reading a bootloader from the eMMC from a first boot area into the memory of the device during the Fast-Boot for the first duration of the eMMC;

starting the bootloader in a CPU of the device;

terminating the Fast-Boot modus after the first duration in response to starting the bootloader;

resetting the eMMC after the terminating;

putting the eMMC in the Fast-Boot modus for a second duration after the resetting the eMMC;

initializing hardware by the bootloader, while reading an operating system into the memory from a second boot area and/or a main data area using Direct Memory Access (DMA); and

starting the operating system from the memory by the bootloader.
