Zynq UltraScale+ MPSoC - PS-PL AXI widths not configured in 2016.3 FSBL


When using an AXI interface with 32 or 64-bit width (or 128-bits for M_AXI_HP0_LPD) and using FSBL to initialize the system, bus width is not configured causing data corruption.


Although this issue was resolved in the 2016.3 release for the Tcl initialization workflow (See (Xilinx Answer 66295)), remains in the FSBL workflow because it uses its own PS-PL isolation removal function, rather than psu_ps_pl_isolation_removal_data().

The current work-around is to include the psu_ps_pl_isolation_removal_data function in the FSBL initialization process:

u32 XFsbl_HookPsuInit(void)
u32 Status = XFSBL_SUCCESS;

/* Add the code here */

Status = (u32)psu_init();

if (XFSBL_SUCCESS != Status) {
* Need to check a way to communicate both FSBL code
* and PSU init error code
Status = XFSBL_PSU_INIT_FAILED + Status;

/* AFI Configuration workaround */

return Status;

This issue will be fixed in the 2016.4 release.
