It is educational to hear a positive statement that the U4WDH Flash is a second silicon device.
I will call it unfortunate that you did not select a part that could work on 1.8V for the SPI interface.
All the U4WDH parts I have tell me there is a generic flash part.
(614) efuse: Loading virtual efuse blocks from real efuses
(615) spi_flash: detected chip: generic
(615) spi_flash: flash io: dio
(618) esp_core_dump_flash: Init core dump to flash
While other non-U4WDH devices tell tell me GD
My assumption had been that you had used the die space that was once a second processor to create your own flash implementation.
Perhaps you are getting bare metal that has not yet had the mfg ID code written into it.
