Partial reconfiguration fails on arria 10, im getting PR_DONE time out and incompatible bitstream error.

I have a specific block in my design which is set to be of type "Reconfigurable" and is placed on "Fixed/Locked" (Fixed with expansion 1) Logic lock region.

The PR controller ip is "Partial Reconfiguration Controller Intel Arria10/Cyclone 10 FPGA IP", and its connected to a 60mhz clk (from a pll)

rest of the signals are not being usedf (only sampled with signaltap)

The PR ip is configured to be an internal host, with jtag debug mode enabled, avalon-mm slave interface disabled, freeze interface is enabled but currently not connected to anuthing, hierarchical PR support is enabled, and Enabled bitstream compatibility is also enabled.

input data width is 32, clock-to-data ratio is 1, divide error detection frequency is set to 2.

enhanced decompression is disabled.

auto instantiate blocks are both enabled and the generate timing constaints file is also enabled.

the entire flow seems to work just fine, and im getting both sof,jic and rbf file for the partition (using switch GENERATE_PR_RBF_FILE ON)

after loading the sof file into the fpga, when i try to perform the PR to the same partition, im getting both PR_DONE timed out and bitstream incompatible errors.

What could i be doing wrong?

Thanks.
