   |bms-master| release :ref:`TI_TMS570_BASED_BMS_MASTER_V1_2_2` is designed
   and prepared for a CAN based bootloader for remote firmware update.
   Follow the instructions to establish bootload compatibility on older
   hardware.

The following specifications must be met to ensure a safe and optimal work with
the |bms-master| hardware.

Bootloader Compatibility on |bms-master| prior to v1.2.2
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

In |bms-master| release :ref:`TI_TMS570_BASED_BMS_MASTER_V1_2_2`, the CAN1
Enable and Standby signals have been wired directly to the MCU, instead of
using |I2C| based port expander.
Therefore, on |bms-master| prior to v1.2.2 the CAN1 transceiver would not be
enabled during bootloader operation, lacking the feature of firmware update
capability.

By desoldering populated 10kOhm pull-down resistors R6320_2 and R6321_2, the
CAN1 transceiver will be enabled by default and is available during
bootloader operation.

Details are shown in
:numref:`resistors-for-foxbms_v1.1.1._bootloader_compatibility`.
