Hi
We have a board with RFSoC XCZU49DR with PS DDR 4GB
We are facing an issue with PS DDR Initialization, The following address returns this:
Address: 0xFD080030 returns: 80C000FF
Which as per this register map: AMD Adaptive Computing Documentation Portal
it is some Deskew done of read and write/ Eye training done error is showing.
We are getting below in vivado command:
xsdb% targets -set -filter {name =~ “PSU”};
xsdb% psu_init
psu_ddr_phybringup_data0
psu_ddr_phybringup_data
start of psu_ddr_reg
start of psu_ddr_reg0
PHY initialization to complete
DDR initialization complete
DDR Dummy reads
DDR before trigger PHY training
data := FD080030: 80C000FFMemory read error at 0xFD080030. Invalid DAP IDCODE ffffffff. Invalid DAP ACK value: 4
We would welcome your suggestions.
We have another working board where the same address returns : FD080030: 80000FFF
