Olimex RP2040-PICO-PC for Raspberry Pi Pico

[homeshopper]

I have an Olimex RP2040-PICO-PC for Raspberry Pi Pico.
On Olimex's web-site there is no instructions of use,
the product description is very vague.
I have looked at the Demo codes:
https://github.com/OLIMEX/RP2040-PICO-PC/tree/main/SOFTWARE
There are three compiled programs, Audio.uf2, DVI.uf2 & SD_card.uf2.
I was able to flash DVI.uf2 to the Pico W,
but nothing outputs from the Olimex RP2040-PICO-PC HDMI port to the monitor.
Only a red light comes on the Olimex RP2040-PICO-PC board, but nothing else happens.
However, I can not find any method or software that will flash SD_card.uf2 to a SD Card.
File Viewer Plus was the only program that would read *.uf2 file formats,
even BOSSA would not work.
I searched for USB file format (*.uf2) both for windows 11 & raspberry Pi 5.
Any ideas what to try next?
I appreciate any help & thank you in advance. Regards, Ian.

"If you don't want to bother with building just use the prebuilt UF2 files, connect the Raspberry Pi Pico to your computer using a micro-USB cable, making sure that you hold down the BOOTSEL button to force it into USB Mass Storage Mode. The board should automatically appear as a external drive. You can now drag-and-drop the UF2 binary onto the external drive."

Hi, Thank you for your message, sorry for the late reply.
I did flash DVI.uf2 to the Pico W attached to the RP2040-Pico-Pc board.
A red led lights, but no output from the HDMI.
Do you have anymore suggestions I could try?
