1. A system, comprising:
a contactless reader configured to transmit a bootloader activation command comprising firmware and an address of a controller of an auxiliary circuit; and
a device, comprising:
a contactless transponder including a contactless interface and a transponder wired interface, and
the auxiliary circuit coupled to the contactless transponder, the auxiliary circuit comprising:
a processor configured to execute instructions,
a bootloader configured to store the instructions in a memory of the auxiliary circuit in a bootloader mode, and
the controller being configured to convert the bootloader activation command to a second bootloader activation command consistent with an inter-integrated circuit (I2C) protocol, wherein the controller is configured to set a terminal of the contactless transponder, through a terminal of the auxiliary circuit dedicated to an activation of the bootloader mode, to a voltage level in accordance with the second bootloader activation command.
