Agilex 5 - HPS first - u-boot stuck if rebooting

Hello,

I have problem after reboot of my system (reboot in linux console or press HPSrst button on AXE5-Eagle devboard), or if I fit fpgacore.rbf from u-boot twice, than boot from emmc stuck on:

Hit any key to stop autoboot:  0
2568192 bytes read in 124 ms (19.8 MiB/s)
...FPGA reconfiguration OK!
switch to partitions #0, OK
mmc0 is current device
Scanning mmc 0:1...
Found U-Boot script /boot.scr.uimg
2751 bytes read in 13 ms (206.1 KiB/s)
## Executing script at 81000000
crc32+ Trying to boot Linux from device mmc0
Found kernel in mmc0

First time (power-on or after press nconfig button on devboard AXE5-Eagle) it boots ok - succesfully continues to OS with:

crc32+ Trying to boot Linux from device mmc0
Found kernel in mmc0
5428330 bytes read in 245 ms (21.1 MiB/s)
## Loading kernel from FIT Image at 82000000 ...

Can somebody help me to overcome this problem?

Thanks.
