Rockbox & V2's

I tried it as well and it works fine except for some crashing plugins here and there and being unable to write access the internal memory & sd card. But audio quality is great.

Being the vintage computer lover that I am, I spent nearly an hour listening to some C64 SID files (great emulation, btw.) and playing Doom. Pure awesomeness!

Well maybe this is a duplicate question–but I’m clearly desperate :

Where can I get the reverse boot-loader to do just the opposite if you wish (boot into Sansa OF by default, unless the REW button is held) as opposed to booting into Rockbox by default.

I’ve not seen a reverseBL for the fuze.  You would be better asking on ABI or rockbox.org.

Changing how the bootloader works on the Fuze is really hard and you risk trashing your player if you make any mistake at all.  I don’t recommend trying to do it.

I still can’t get RB to load while plugged into a wall charger with my V1 Fuze. I boot it up with RB then hold down the center select button while plugging in the USB cable into the bottom of the Fuze. Still loads the OF.

OF latest

RB 3.5.1 latest build

Same here, although experienced it little differently-I switch on my Fuze, it boots to RB. Then I plug it into a wall charger for charging. It then seems to reload the OF instead…Wiered.

Strange and confusing…Look here : http://forums.sandisk.com/sansa/board/message?board.id=sansafuse&thread.id=10767&view=by_date_ascending&page=1 where Tapeworm stated, and I quote :

If you want to boot into the Sansa firmware upon start-up, you hold the REW ( |<< ) button down during start-up. You can also install a reverse boot-loader to do just the opposite if you wish (boot into Sansa OF, unless the REW button is held).

That is exactly as how it is supposed to work given the current state of USB support in Rockbox for the Sansa Fuze. Rockbox on the Fuze can’t detect if the USB connection is to a PC or to a wall charger and any powered USB connection made forces a reboot to the Sansa firmware.

I don’t think this ‘reverse bootloader’ exists. At least not an “official” one from the Rockbox developers. If real, I would still stay away from it after saratoga’s warning.

There was one for an older player (e200 I think), although I don’t think it was “official”.  I don’t really see the point tbh, I spend as little time in the OF as possible.  Tapeworm doesn’t use rockbox, that’s probably why there is confusion.

Eh? But Tapeworm posted that in the Fuze forum. That’s why it is potentially misleading.

Well, my wife loves the radio and the videos (accessible thru the OF but not thru RB), and hates depressing the << to boot to OF. This is one need for the reverse bootloader, which, from the comments I have received, is non-existent.

“and any powered USB connection made forces a reboot to the Sansa firmware.”

Unless you hold SELECT down. This allows you to stay in the RB FW and charge the device.

I was indeed referring to the e200v1 series player when I mentioned the reverse boot-loader. And yes, I do use RB on my player of that vintage. I even created/wrote my own theme.

I don’t have a Fuze at the current time (as it’s on semi-permanent loan-out), but saratoga would be in a position to know whether or not this BL was available or advisable on the Fuze port. You could also review and search the Rockbox site itself for more info on it. Remember the e200v1 port has been out for several years; the Fuze (and all the AMS or v2 variants) have just successfully been ported fairly recently. This feature/function/option may come in time, or it may not as demand or hardware restrictions may discourage it.

When just venturing into Rockbox some time ago, I too thought this would be a handy feature, but have to say in actual usage, it’s not a big deal to hold the REW |<< button during start-up to boot into the OF.

Sorry for the confusion; one tends to lose track of where one is when jumping around all the different boards around here, and general information sometimes gets posted without conscious thought to individual idiosyncrasies of all the different players.

Just to be clear theres no reason you can’t make a reverse bootloader safely.  Its just harder since:

  1.  The dual boot choice is actually made before the bootloader in the mkamsboot program, which is written in ARM assembly 

  2.  Theres no way to recover from flashing a broken binary with mkamsboot

  3.  Theres no easy way to test the binary before flashing it

So basically you have to be at least a little familiar with ARM assembly and be willing to break your player to write one.  Thats not most people who use the Sandisk firmware :slight_smile:

OK Tapeworm, saratoga, thanks for the clarifications. I’m not a dev guy, BTW, but the tech details help to reinforce what you guys have said–its not advisable to go for a Reverse Bootloader at the moment.

My Fuze FM radio is not working in OF. I was hoping to see a Radio menu item in Rockbox just to verify whether it works and if it does, then it could only be some problem in the OF.

This might sound a little dumb, but how do I get to the FM radio in RB? I have the latest build of RB installed.

The status chart next to the install directions says “FM-Radio:  No” for the Fuze V2, so I think you have to wait for someone to add support for it.

Sorry, I have Fuze V1. No radio for this too? Can you give me the URL for the status chart for V1 (Again sorry for another dumb question)

FM radio works on my Fuze. It’s on the Rockbox main menu, just under Recording.

My fears were not unfounded, after all, I see no FM Radio under Recordings. Does it have to do with FM Radio going bust in my original Sansa firmware? Is there any connection with that?
