4.4.3 JTAG programming adaptor.
Globalstar can supply a programming adaptor that permits programming the processors at a low level without the
bootloader. It is most strongly recommended that if this method is used, that a combined image, with application and
bootloader merged, be loaded so that the device remains field-upgradable later.
Globalstar part number TBD:
A JTAG programmer may be connected by a standard JTAG connector to the JTAG input of this breakout board.
