Writing LPC54005 external SPI flash with blhost fails

Hello,

I'm trying to write to a 4Mbit external SPI-Flash (normal Flash, not SPIFI) connected to Flexcomm 3 of the LPC54005 on my customer target Hardware.

I followed these instructions:

https://community.nxp.com/t5/LPC-Microcontrollers-Knowledge/Use-blhost-to-program-erase-LPC54-S-0xx-...

I downloaded and built the LPC54s018 flashloader project that is mentioned and created a binary.

I am able to download the flashloader.bin to LPC54005 RAM.

I can talk to the flashloader with the blhost tool.

But the "fill-memory" instruction gives me an error:

Does anyone have an idea what's wrong ?

Do I have to configure the LPC54s018 bootloader project before I build it ?

I tried this project configuration, but it did not work either

Your help is very much appreciated.
