I tried to flash ST536 TOS earlier. Regardless of bank it would come up random errors during verify. But blank check verify was fine. Ironically it flashed generic 206 just fine originally.
I now have a puzzle which could be related but flashy clock runs the MB ROM when it is disabled so you can program the flash etc. though the MB ROM jumper (driven form GLUE) was not fitted, and it booted up, which should be impossible. Flashy shouldn't boot 206 as its corrupted and ST536 TOS won't even run on the ST.
So I need to look at the flashy logic next because it should only be running from the motherboard ROM when in disabled mode..and that was "disconnected" at the LS11 for GLUE ROM enable....

At this time, it is unfortunately not possible to whitelist users when your IP changes constantly.
You may inadvertently get banned because a previous attack may have used the IP you are now on.
So I suggest people only use fixed IP address devices until I can think of a solution for this problem!

Re: Flashy Clock - Yet another DEV board
Been pulling my hair out all day because my previously working flashy clock board decided to start coming up all sorts of weird faults :roll:
I thought I might have broken the firmware or something in a later version but after much investigation there is pretty much no real difference between the previous board and the new one..
The previous version 7.0 works fine in the H5.. The latest 7.1B did not, as shown in the image above.
TL;DR - I resoldered the header pins and all is fine again..
So another black mark against PCBWAY.. I can honestly say they are definitely in the top companies in my PCB blacklist now. I've dealt with some pretty bad companies over the past 20+ years, but badly soldering 2 totally different orders now.. and I am having to fault find every board as well.. I thought JLC was bad, but PCBWAY is a order of magnitude worse it seems. :roll:
It would have been quicker to assemble all the boards myself!
:sigh:

Re: Flashy Clock - Yet another DEV board
Been swapping between Grok and GPT to write the time setter program. Both seem to make silly mistakes. But I put Claude to the test and it found the problem and fix it straight away which I was pleasantly surprised about !
So now...
Of course this is as good as I can currently make it. Because as said previously, Control Panel seems to get the date from the keyboard RTC which isn't compatible with flashyclock. And it's not y2K compliant.
Programs which access GEMDOS system time is fine as shown in the image. But the XBIOS calls are for the keyboard RTC which is basically "broken" these days.

Re: Flashy Clock - Yet another DEV board
Somebody found this in another forum for the Y2K problem, maybe this is of any help…

Oddly after Claude fixed the time setter program, the control panel now shows the correct year as 26 , that shouldn't be possible should it :shrug:
AI fixed up @agranlund's , it runs, but now im not sure how to test it worked. I was using CP as the test as the year never worked, but now it does :stars:

Re: Flashy Clock - Yet another DEV board
OMG ! Claude AI fixed the whole thing from @agranlund code ! It even wrote a readme about it all !! :shock: :shock:
Obviously Control Panel in no way is able to talk to flashy clock out of the box..
So.. I make sure Control Panel has the date as all zeros.. Then make sure flashy clock has the same...
Then I set the date in Control Panel...
And verify it is loaded in flashy clock !!!
Is just mind blowing.. Yes only setting the date ... BUT.. its the XBIOS trap which is working to actually allow that to happen !
.. And just to make sure I am not being fooled.. (rebooted without the XBIOS driver)
I set Control Panel to all 1's for the date..
Then loaded flashy clock util...
This would have likely taken me years to figure out !!!
:girldance: :cheer: :girldance: :cheer:
So thanks to @agranlund for doing the grunt work there ;)

Re: Flashy Clock - Yet another DEV board
Ah that's awesome, great stuff!
Happy to have contributed a little bit to the cause with that old code :)

Re: Flashy Clock - Yet another DEV board
Hi,
@exxos do you know already if and when some of these Flashy Clocks will make it to your store?
I am collecting a few things to exceed the 150,- minimum order for us EU folks (need one of the Trudies and some other stuff)
Cheers
Michael

Probably a couple week's. I need to resolder all the headers and test them yet.LarryL wrote: 25 Feb 2026 15:53 @exxos do you know already if and when some of these Flashy Clocks will make it to your store?
