nrf54L15DK with display (SPI)

Question

Hello, 
 
 Did anyone get nrf54L15 to work with a TFT display over SPI? 
 
 I have been using the 1.28" 240x240 gc9a01 in several projects with nrf52840 (both using the DK and custom board designs). 
 
 Now I am evaluating the nrf54L15DK. But I am baffled by the pin layout. I understand the THEORY, and get it to work well on the older chips (like nrf52840DK). It seems that only SPI00 is available in nrf54L15. Do I need to modify the board to remove the external flash? That seems very extreme for such an easy test...

Does anyone have a working overlay file and a wiring diagram? I am using SDK 3.0.2.

I was actually able to get it to work. I set the VDD to 3.0V (using the board configurator), and then I tested each pin on the nrf54L15DK so see what I can use. It seems that its very limited, but I was able to use 1.07-1.13. And importantly connect VDD to VDDIO and not VBUS. The display now works like a charm. But its generally a bit annoying how few gpios as available on the nrf54L15. I guess I can cut out the external flash and thus enable more pins..
