The invention discloses an FPGA on-
orbit debugging method for component flight
verification, and the method comprises the following steps: S1, enabling a debugging
client to be connected with a groundstation through a cable, enabling the
ground station to initiate a transmission request to an on-
orbit spacecraft antenna terminal through a
satellite-ground
communication link, waiting for the establishment of communication, and then the ground terminal initiating an FPGA downloading or debugging
information transmission request; S2, after receiving the request information, the on-
orbit spacecraft antenna terminal transmitting the connection establishment information to the MCU through the
Ethernet; S3, the MCU receiving and analyzing an
Ethernet data packet containing FPGA downloading or debugging information, and then sending the information to the FPGA through a user-defined JTAG link; S4, after receiving the information of the downloading or debugging information request
ground station, the FPGA returning response information and
handshake data to the MCU; and S5, after the MCU receives response information and
handshake data returned by the FPGA, the information being transmitted to the on-orbit
spacecraft antenna terminal through the
Ethernet.
