BOOTLOADER CONTROL VIA DEVICE IDENTIFIER
First Claim
1. An apparatus comprising:
- a data processing apparatus; and
a non-transitory computer readable storage medium in data communication with the data processing apparatus and storing instructions executable by the data processing apparatus and upon such execution cause the data processing apparatus to perform operations comprising;
automatically determining, for three or more executions of a boot process of the apparatus and during the respective boot process of the apparatus, whether a device is connected to the apparatus;
in response to determining that a device is connected to the apparatus, determining, for each of the three or more executions of a boot process, whether a type of the device is a particular type;
for at least a first execution and a second execution of the three or more executions of the boot process and in response to determining that the type of the device is of the particular type;
determining, for each of the two or more executions of a boot process that include the first execution and the second execution, a device identifier for the device;
comparing, for each of the two or more executions of a boot process, the device identifier for the device with a predetermined identifier that indicates a device to which the apparatus should provide control of the boot process to determine whether the device identifier is the same as the predetermined identifier;
for at least the first execution of the two or more executions of the boot process and in response to determining that the device identifier is the same as the predetermined identifier, maintaining the apparatus in a bootloader state to provide control of the boot process of the apparatus to the device; and
for at least the second execution of the two or more executions of the boot process and in response to determining that the device identifier is not the same as the predetermined identifier, continuing the boot process of the apparatus; and
for at least a third execution of the three or more executions in response to determining that the type of the device is not the particular type, continuing the boot process of the apparatus.

Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for placing a device in a bootloader state. One of the methods includes determining, during a boot process of the apparatus, whether a device of a particular type is connected to the apparatus, in response to determining that a device of the particular type is connected to the apparatus, determining a device identifier for the device, comparing the device identifier for the device with a predetermined identifier that indicates a device to which the apparatus should provide control of the boot process to determine whether the device identifier is the same as the predetermined identifier, and in response to determining that the device identifier is the same as the predetermined identifier, maintaining the apparatus in a bootloader state to provide control of the boot process of the apparatus to the device.

11. A non-transitory computer readable storage medium storing instructions executable by a data processing apparatus and upon such execution cause the data processing apparatus to perform operations comprising:
-
automatically determining, for three or more executions of a boot process of a first device and during the respective boot process of the first device, whether a second device is connected to the first device; in response to determining that a second device is connected to the first device, determining, for each of the three or more executions of a boot process, whether a type of the second device is a particular type; for at least a first execution and a second execution of the three or more executions of the boot process and in response to determining that the type of the second device is the particular type; determining, for each of the two or more executions of a boot process that includes the first execution and the second execution, a device identifier for the second device; comparing, for each of the two or more executions of a boot process, the device identifier for the second device with a predetermined identifier that indicates a device to which the first device should provide control of the boot process to determine whether the device identifier is the same as the predetermined identifier; for at least the first execution of the two or more executions of the boot process and in response to determining that the device identifier is the same as the predetermined identifier, maintaining the first device in a bootloader state to provide control of the boot process of the first device to the second device; and for at least the second execution of the two or more executions of the boot process and in response to determining that the device identifier is not the same as the predetermined identifier, continuing the boot process of the first device; and for at least a third execution of the three or more executions in response to determining that the type of the second device is not the particular type, continuing the boot process of the first device. - View Dependent Claims (12, 13, 14)

16. A computer-implemented method comprising:
-
for each of multiple boot processes of a first device; determining, during the boot process, whether a device of a particular type is connected to the first device; for a first subset of the multiple boot processes in response to determining that a device of the particular type is not connected to the first device; continuing the boot process of the first device; for a second subset of the multiple boot processes in response to determining that a device of the particular type is connected to the first device, the second subset mutually exclusive from the first subset; determining a device identifier for the device of the particular type; comparing the device identifier for the device of the particular type with a predetermined identifier that indicates a device to which the first device should provide control of the boot process to determine whether the device identifier is the same as the predetermined identifier; and in response to determining that the device identifier is the same as the predetermined identifier, maintaining the first device in a bootloader state to provide control of the boot process of the first device to the device of the particular type. - View Dependent Claims (17, 18, 19, 20)
