xilskey_bbram_ultrascale_example.c
Accessing Ultrascale microblaze 's BBRAM is done by using block RAM initialization. Master Jtag primitive has to added to design i.e MASTER_JTAG_inst instantiation have to performed and AXI GPIO pins has to be connected to TDO, TDI, TMS and TCK signals of MASTER_JTAG primitive. All Inputs(TDO) and All Outputs(TDI, TMS, TCK) of MASTER_JTAG can be connected as 1) All Inputs to one channel All Outputs to other channel Valid example: All Outputs connected to Channel 1 Input signal TDO also connected to channel 2 2) All Inputs and All Outputs to same channel. Valid example: All Outputs connected to Channel 1 Input signal TDO also connected to channel 1 3) But some of the Outputs in one channel and some of them in different channel is not accepted. Invalid example: All Outputs connected to Channel 1 Input signals (TDI, TMS) connected to Channel 1 Input signal TCK also connected to channel 2
The design should only contain AXI bram Ctrl memory mapped(1MB). Note: MASTER_JTAG will disable all other JTAGs Procedure to access BBRAM of Ultrascale: 1) After providing the required inputs in xilskey_bbram_ultrascale_input.h, compile the project. 2) Generate a memory mapped interface file using TCL command write_mem_info $Outfilename 3) Update memory has to be done using the tcl command updatemem. updatemem -meminfo $file.mmi -data $Outfilename.elf -bit $design.bit -proc design_1_i/microblaze_0 -out $Final.bit 4) Program the board using $Final.bit bitstream 5) Output can be seen in UART terminal.
MODIFICATION HISTORY:
Ver Who Date Changes
5.0 vns 09/01/16 First Release. 6.0 vns 07/28/16 Updated example to allow counting configuration feature and to program Obfuscated key. 6.7 psl 03/20/19 Added BBRAM key write support for SSIT devices. psl 03/29/19 Added Support for user configurable GPIO for jtag control. 6.8 psl 05/21/19 Initialized SystemInitDone ,to indicate XilSKey_Bbram_JTAGServerInit status. And passed BbramInstancePtr instead of InstancePtr in XilSKey_Bbram_JTAGServerInit.
