And you have any idea what can be wrong in our tests: using the QSPI flash MX25L25635FZ2I-10G and write the RCW file rcw_1600_qspiboot.bin.swapped from packages/firmware/rcw/ls1043aqds/RR_FQPP_1455/ in address 0x0, and u-boot.bin/u-boot-dtb.bin (generated using ls1043aqds_qspi_defconfig) in address 0x100000 we could not seen any output/print in our board.
