1.1.3.2.1. cli.cmd_bootloader.bootloader.Bootloader

class cli.cmd_bootloader.bootloader.Bootloader(interface: BootloaderInterface, path_app_binary: Path | None = None, app_size: int | None = None, path_crc_64_table: Path | None = None)

Implementation of the communication between host-implementation of the bootloader and the embedded bootloader.

__init__(interface: BootloaderInterface, path_app_binary: Path | None = None, app_size: int | None = None, path_crc_64_table: Path | None = None)

Init function.

Parameters:

  • interface – the communication interface of the bootloader

  • path_app_binary – the path of the binary file

  • app_size – the size of the binary file of the application

  • path_crc_64_table – the path of the temporary file that stores the CRC table

Methods

__init__(interface[, path_app_binary, ...])

Init function.

check_target()

Check if the bootloader can be reached and print its current status.

reset_bootloader()

Reset bootloader

run_app()

Run application on bootloader

send_and_validate_vector_table()

Send vector table to the bootloader

send_app_binary()

Transfer the app binary to the embedded bootloader

send_app_data(i_loop)

Send the application binary file as data in 8 bytes (and calculated crc in 8 bytes) to the embedded bootloader.

send_data_as_a_sector(i_loop, ...[, ...])

Send data of one sector to the embedded bootloader.

send_data_as_a_sub_sector(i_loop_start, ...)

Send one sub-sector of data to bootloader.

send_pre_info()

Send CAN message to the embedded bootloader to let the embedded bootloader prepare for receiving the application data.
