Re: PetifFatFs (SDCARD)

**EDIT** Thanks Uze! The fix works great and I can navigate the entire world of Hyrule using the emulator now. Now I can develop away from home again. This may have already been fixed but I thought I'd share an update to the seek and file position bug. Seems that seeking DOES work in the emulator b...

Re: Protecting the bootloader when using ISP

Some cards tolerate it and some not. I don't think we can do much on this one. I usually "un-click" the SD card before ISP flashing, otherwise I have the same problem. I have a really simple test for this now. Takes the guesswork out of it. // Check that the SD card is working pf_mount(&a...

Re: Protecting the bootloader when using ISP

Seems I was too quick to call it done.

New games don't start up. The bootloader is still accessible though.

I flashed a game and removed the -D switch from avrdude. The game starts up but the bootloader is gone again.

I still have the same problem.

Re: Protecting the bootloader when using ISP

Super! Thanks Uze. I'm using the bootloader-fix.hex file that you provided me recently in another thread. Is IT now the official bootloader? Are people that develop directly on the hardware just using the bootloader/SD solution? I'm using my ISP because I can control it all from the PC.I have a batc...

Re: Protecting the bootloader when using ISP

Then perhaps a combining of the game and boot loader text into one hex?

Protecting the bootloader when using ISP

This will flash the bootloader: avrdude -p m644 -c usbasp -P usb -U flash:w:Bootloader_fix.hex But if you want to flash your game then you lose the bootloader. avrdude -p m644 -c usbasp -P usb -U flash:w:game.hex Is there a way to prevent bootloader overwrite? Some kind of write protect? I started t...

Re: Movie Player not working

So, I tried to program my Uzebox with my ISP, and it worked. It also removed the bootloader. I suspect it is because i did an erase cycle on it first. I flashed the bootloader, and used it to flash my game. The bootloader is back. I'm pretty sure this wasn't the way to do it, or maybe it was. Is the...

Re: PetifFatFs (SDCARD)

I may have found another bug. Seems that I cannot go past 65535 in the emulator. // Lousy fix for the emulator bug. if(buggyemulator == 1 ){ for(unsigned char multiple = 0; multiple <= themap; multiple++){ for(unsigned int findex=0; findex < sizeof(screenbuffer1); findex++){screenbuffer1[findex] = 0...
