Zynq UltraScale - PL MicroBlaze is not detected in the XSDB

Description

I have a MicroBlaze on my Zynq UltraScale PL, which is properly clocked and reset. However, when I try to debug this in SDK, it is missing from the JTAG chain.

How can this be resolved?

Solution

This is a known issue on the ES1 silicon and this issue only presents itself if the MDM ID code SRL16s is set to a certain LOC. 

To work around this, change the LOC to another location.

You can put the following constraints in the top-level XDC file. The location used is known to not exhibit this issue:

For Vivado 2016.3 and 2016.4:

set_property LOC SLICE_X58Y73 [get_cells design_1_i/mdm_1/U0/MDM_Core_I1/JTAG_CONTROL_I/Use_ID_SRL16E.SRL16E_ID_1/Use_unisim.MB_SRL16E_I1]
set_property LOC SLICE_X58Y73 [get_cells design_1_i/mdm_1/U0/MDM_Core_I1/JTAG_CONTROL_I/Use_ID_SRL16E.SRL16E_ID_2/Use_unisim.MB_SRL16E_I1]

For Vivado 2016.2:

set_property LOC SLICE_X58Y73 [get_cells design_1_i/mdm_1/U0/MDM_Core_I1/JTAG_CONTROL_I/Use_ID_SRL16E.SRL16E_ID_1]
set_property LOC SLICE_X58Y73 [get_cells design_1_i/mdm_1/U0/MDM_Core_I1/JTAG_CONTROL_I/Use_ID_SRL16E.SRL16E_ID_2]

Note: You many need to adjust the path prefix "design_1_i/mdm_1" depending on your actual design.
