Re: [M100] odd REX error - anybody run into this?
Might also check that none of the solder joints have gone bad. The board might start out fine but as the solder oxidizes over time a badly soldered joint could fail. Re-programming may resolve the problem but if there is a bad joint it will just happen again or you may not be able to reprogram the device. Worth a close inspection to make sure especially with hand assembled part. Could also try this REX in another machine see if it behaves the same way.

Good point - I did try re-seating the module (no luck) but I should make a physical examination of the socket and also try swapping it with the working REX from my machine, when I next have a chance. jim

It installs REXMGR on the menu, as you'd expect. Launching REXMGR gets you stuck back at the same screen again, though. > Did you make sure to remove the flux after soldering? The flash chip > is especially sensitive to excess flux residue (in my experience). I don't think I did. I used a flux pen and a barely-visible amount of flux when I built it so I don't know if there's really anything there to remove. I'd have to check. This issue can most likely be resolved by re-loading the REX software, but I'm just hoping for an alternative fix that might keep the data intact - my son is very concerned about losing his stuff (although he was only gone to his mom's house for two days with it so I can't imagine he's lost much - there was a program he was working on to play a new song he's been composing). jim

You might try unseating REX, checking that the metal fingers in the socket are all ok and working, then re-seat REX. Just trying to think of something.

My son's REX (in his M100) is in a strange state. I don't know what exactly he did just before initially getting this message, but now he gets this every time he runs REXMGR. The REXMGR screen appears with the top line saying "REX 4.9 M Group:RAM" and the rest of the screen blank except for the following on the bottom line: "no blank sector pair found" Cold reset and CALL 63012 just leads back to the same screen. The "no blank sector pair found" message is flickering every second or so, as though it is being re-drawn. Any ideas? Is there a possibility of recovering from this with the contents of flash intact, or are we going to have to go straight to reloading REXMGR into the module so it re-formats the flash? jim

Re: [M100] odd REX error - anybody run into this?
Do option ROM images still work? I've never encountered this before, but it kinda sounds like all the flash sectors have been filled, which I didn't think was possible. Either that, or the flash has failed somehow. Stephen would probably know better than I though. Where did you get your REX device, and how old is it? -Josh On Fri, Jun 29, 2018 at 2:11 AM, Jim Anderson wrote: > My son's REX (in his M100) is in a strange state.
