RTC clock issue

[ghost]

Hello,

I noticed the DATE and TIME settings aren't stored when using the MSX_MIST core with Nextor kernel.
I expected that I can manually change the DATE and TIME setting in Nextor, but instead the DATE is shown as 00-00-0000, which is incorrect.

Maybe I also can use an USB Ethernet / wifi adapter to get the real current date and time from the internet as well?

Currently the USB-RTC is the only source for the date/time info.
Fetching from internet would require a TCP/IP stack in the firmware.

OK, I see, thanks! Which dongles are supported? And it will also work with other cores like Next186?

There's some info in the Wiki:

And also there's a forum thread:

Okay, thanks!

And without the USB-RTC, any chance to add an option in the OSD menu (just like where to mount the VHD image) to manually enter the date and time and pass it to the (MSX) core? If we need to write some files, then the correct setting can be used with a workaround.

Or add an option to switch between current RTC from MiST and RTC from 1chipMSX, part of KdL's OCM-PLD pack 3.9?

Probably this one would be the better solution.

Okay, great!

Just curious: How much space is used with the current MSX core on the MiST?

[gyurco]

It's not very big, about 60-70% FPGA space is used.
