No messages from UART

I have LS1046A-RDB and I cannot boot it up. There is no UART messages. I've tried both options (micro-USB and RJ-45). This happened after failing to flash the QSPI firmware for another board (FRWY-1046) using the quick start guide as shown below.

Any help is appreciated. Thanks!

To start the board recovery, it is recommended to prepare bootable SD card.

Composite firmware image "firmware_ls1046ardb_uboot_sdboot.img" can be downloaded from:
https://lsdk.github.io/components.html
section LSDK IMAGES

Using a Linux machine write the firmware image to SD card at offset block (512-byte) 8:

    # dd if=firmware_ls1046ardb_uboot_sdboot.img of=/dev/sdX seek=8 bs=512

(sdX should correspond to actual name of the SD card device)

After preparing the SD card refer to the QorIQ LS1046A Reference Design Board Getting Started Guide, 8 DIP switches (SW5[1:8] + SW4[1]) and set RCW_SRC[0:8] = 0010_0000_0: SDHC/eMMC

Insert SD card and power-on the board.
