How  many times do I need to say the same thing? - you have asked the same before and I explained then

OPTION RESET OLIMEX is not valid for the HDMIUSB firmware only the HDMI firmware. The concept of OPTION RESET is that is configures a board WITHOUT any other additions to work "out-of-the-box". The Olimex needs an additional USB/UART to work as a USB host and therefore is not supported in HDMIUSB firmware.

thanks. got it. I thought it worked on one release but with trying so many versions I may be confused. maybe olimex 2040.
olimex pico2 hdmi is easy to try hdmi graphics.
pico2 vga usb is interesting to with new graphics.

@Peter: an “OPTION PLATFORM OLIMEXUSB” would be really nice and desirable.
You can also do without a console (COM2 ), then I supply the board with a USB power supply via the USB port underneath and have a small standalone computer :-)

Just set the options by hand - it isn't realistic to add every variant of how a board might be used

You can create your own setup file with:-

OPTION DISK SAVE fname$
OPTION DISK LOAD fname$

if no extension specified defaults to ".opt"

The first saves a binary file of Option List and the second restores all the options in one go.

Peter sir, sorry for annoying you. I can be stupid.

Yes, that's what it should do. It's the only speed that HDMI will work at, apparently.

HDMI runs at three speeds depending on the resolution. When you change the resolution it automatically changes the speed

640x480 315MHz
1024x768 324MHz
1280x720 372Mhz

Previous to RC5 you could change the CPU spped but this was a mistake because it would b....r the video output

yes Mick, I thought that... but people post different screen res and different freq.
I'm just experimenting pico 2 and drop in replace 2040 all ok. ili9341 is just faster, not spi, the code.
vga usb is "better" than hdmi?
I got pico 2 vga and hdmi same monitor...not same time
could Peter not posted olimex options for hdmi usb and said copy one line at a time in mmcc? save me being a bother. ps like mmcc

Ah, thanks Peter. I suspected that because of the way my monitor plays up.

--------------------

Stan: It's still being designed. I wouldn't read too much into what people are doing.
When you get options sorted for a particular setup save them using OPTION DISK SAVE and get them back using OPTION DISK RESTORE. It's best if you save your setups to SD card, I've found. If they all get wiped you only need to manually set up the SD card then and you can load all the rest. That's a way to get round custom option setups and it works well.

As for whether VGA is "better" than HDMI, it all depends on what you need! VGA needs two less pins and is happy with wires all over the place, but it has limitations like 16 colours max that you can't change as they are decided by hardware.

Would you like a set of Gemini PCBs? I can fit either a VGA or a HDMI socket for you and some SMD bits if you want them and I happen to have them. You'd still need to get some stuff from Ali Express as I haven't got everything - and you get to solder stuff onto a PCB for a change too! :) Let me know if you are interested. You can plug in either a Pico or a Pico 2 for VGA, or just a Pico 2 for HDMI but the board can only be built to accept one sort of video as both sockets fit in the same place.

Hi Mick, thanks for the generous offer but I got several boards covering new pico 2 usb hdmi, usb vga, ili9xxx usb.
if options work I copy from mmcc to notepad and save as .txt in documents.
