Hi Peter,

I checked several images. This happens in all of them. first tested is V6.00.01.
There is no relation with a C drive.

After reset there is an MMBasic startup time. When the LCD is powered, but before it is initialized by MMbasic, the LCD is bright white. When MMBasic initalizes the LCD it is becomes dark. This behaviour has always been the same.

When the "picofrog" problem shows, the "white time" of the LCD is far longer (seconds). And after initialization the SD card is not accessible. And that is why the watchdog in the menu kicks in (timeout on SD card).

For now, please ignore this "picofrog" problem. It could very well be a hardware problem. Since all versions have it. The only thing you could look into is what logic is behind the execution of the program in main memory after a watchdog or reset, and not the menu in flash slot 1. That is something that could be withing MMBasic.

I will look into the "hardware problem".
Picofrog is multi platform, maybe there is trigger to make it think it is not running on a Game*Mite, and then it could try other controllers (i.e. NES). Maybe reprogramming GPIO pins in conflict with Game*Mite hardware (SD card CS ?).

But the "white time" of the LCD is also a thing to look at. Why does it take seconds longer to init the LCD.

Your "mini" seems not be causing this problem.

Hi Peter,

It was a hardware problem. The SD card adapter was flash. I have no idea how something like that could be so respectabel, but it was.
Anyway… issue solved.

That's bizarre, anyway good to know - thanks

@Peter,

I assume you did not include tilemap in the last mini release, correct ?

Volhout

No: it is there in the MIN build just posted on the 6.02.02 beta thread
