Unable to boot from QSPI using Quartus 19.3

So I followed the procedure for Quartus 17.1 given here: https://rocketboards.org/foswiki/Documentation/A10GsrdQspiBootLTS

I was able to boot on the Arria10 using SD Card and QSPI using precompiled kernel and rootfs and my own compiled kernel and rootfs.

When I try to follow the procedure for 19.3, given here:

I compile the rootfs and zImage using the instructions in the Appendix on the above page and load the binaries on to the Arria10 devkit using the quartus_hps commands.

I always get the errors given in the screenshot attached here:

I have tried using tftp as well but I always get the same error:
jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x...: 0x.... instead

I cannot find any help regarding this. I am sure that the partitions are being correctly defined in the device tree and I am loading the jffs2 at the correct address.

What should I do??
