unrequited Posted July 22, 2008 Report Share Posted July 22, 2008 They forgot to mention in the update walkthrough that leaving the test mode folder on the sd card keeps booting you into windows ce. I used this to copy and back up my f90bt's file system onto my sd card. Hopefully I'll be able to figure out why my TTS doesn't work, as well as maybe figure out where the graphic icons lay so I can stick my car onto the GPS map. Other more adventureous members with CE experience might want to poke around further. Quote Link to post Share on other sites
unrequited Posted July 22, 2008 Author Report Share Posted July 22, 2008 One thing to remember is that the entire file system is held in ROM, so you can't change it. If you remember the update procedure, there's that weird white and then blue screen where it's actually rewriting the rom. You can't just copy/paste files TO the flash disk, although you can copy from it. So at least for now, don't worry about breaking or bricking your AVIC. Quote Link to post Share on other sites
seanthings Posted July 22, 2008 Report Share Posted July 22, 2008 how do you go into test mode? I left the testmode folder, LPUE080 folder, and MiTACAP folder on my SD card. Everytime I boot up with the SD card in the slot, it goes and does the 2nd update..again, where there is a bar and it says ok at the top left when its done. I try to touch anywhere on the screen and it doesn't respond. If I reboot it will go through the same "update" process, at the end...again it doesn't respond after its done.

CatchMeIfYouCan631 Posted July 22, 2008 Report Share Posted July 22, 2008 when i did it, it had "copy" minimized in the start bar, and i pressed that to open it. after that i didnt know if the update was finished or not and i think i jus pressed the ok button ora small x in the top right and it takes you to windows ce Quote Link to post Share on other sites

What do you think an SD Card or USB Thumb drive is? They are actually Flash ROMs and can be written to. It doesnt make much sense to call them ROMs, but they are. I actually wish I was a Linux Guru, because it now seems possible to put Linux on these drives. Windows CE and Mobile are notoriously clunky. I am farily certain a good deal of processes are loaded that the 900Bt does not need. Quote Link to post Share on other sites

It doesnt make much sense to call them ROMs, but they are. They aren't ROMs, actually. They're RAM. By ROM's very name, it can't be changed, being read only memory and such. That's why they came up with the acronym "RAM", so people could randomly access the memory. Quote Link to post Share on other sites

That's why they came up with the acronym "RAM", so people could randomly access the memory. Flash memory is EEPROM: Electrically Eraseable and Programmable Read Only Memory. These, very much like Flash ROMs can be written to. CD ROM can be written to as well! http://en.wikipedia.org/wiki/Flash_memory So, ROMs can be written to.... its semantics at any rate. Its just an old term - like calling a 3.5" floppy disk floppy, even though it was not. The point is that the Flash memory on the AVIC can be written to. Quote Link to post Share on other sites
unrequited Posted July 22, 2008 Author Report Share Posted July 22, 2008 They are actually Flash ROMs and can be written to. Yes, obviously with the update last night I know they can be written to. I even specifically without using their Flash ROM writer all you can do is pull stuff off the flash, not write to it. Please reread my comment above Quote Link to post Share on other sites
fatherfork Posted July 22, 2008 Report Share Posted July 22, 2008 ...like calling a 3.5" floppy disk floppy, even though it was not... The disk inside was floppy. Otherwise, good points. I stand incorrect. Quote Link to post Share on other sites

Not that I would recommend modifying the system, but I have a hard time believe that it is not writeable. It is no more Read Only than the SD card you insert for the update. They are all Flash ROMs. It shows up in My Computer as a standard drive from what I recall. Quote Link to post Share on other sites

I stand incorrect. Semantics. I still would not touch the data on the drive at any rate. Ugh, I apologize for coming off so cranky as well. Lots of cranky folks around here... its really frustrating dealing with the problems on this system. Quote Link to post Share on other sites
CatchMeIfYouCan631 Posted July 22, 2008 Report Share Posted July 22, 2008 tacomaboy, is it possible to copy the files onto your sd card and then play with it on your desktop? so you can explore but not mess up the unit? Quote Link to post Share on other sites

You're missing the point and getting hung up that I keep calling it an unwriteable Flash ROM. It's unwriteable until we can figure out a way to use the white/blue screen updater. Once it boots up it's locked. You've obviously never done this before concerning WinCE devices/GPSs. Start reading up on gpspassion.com please. Quote Link to post Share on other sites
tacomaboy Posted July 22, 2008 Report Share Posted July 22, 2008 tacomaboy, is it possible to copy the files onto your sd card and then play with it on your desktop? so you can explore but not mess up the unit? I have not tried, but I assume so. Remember, the "Desktop" is part of the AVIC-F's on board Flash Drives file system. So in essence copying files to it is writing to the Flash drive. My concern is with messing up the drivers and applications installed that run the AVIC GUI that we see under normal operation. I seriously doubt putting files to the desktop will affect that. Just dont go messing around in the program files area. Exploring (viewing) is fine, I probably will do that some this evening. Just don't delete! Quote Link to post Share on other sites
