You can use u-boot from SD card for QSPI NOR burning.
CodeWarrior Flash programmer also can be used for QSPI NOR programming.

Try to use the Table 51 and Section 4.4.8.8 from SDK 2.0-1703 documentation for programming new u-boot on the LS1046ARDB board:

Hi Pavel, thank you for looking into this however my experience was similar to JS Park in this message.

Despite following the programming guide directed to NOR flash 0, I would notice the first 0x8000 bytes would silently fail to erase/write. It may not be a coincidence that this is also the first 8 4kB 'hybrid' sectors of S25F512S though I don't have drivers to lock/unlock the QSPI configuration register default settings. I was lucky to have access to a CodeWarrior and TAP/cable and recover this.
