panic on load-image #4

Closed incanus closed 10 months ago

incanus commented 10 months ago

With release 4 (28e546a6dc63bc6083ada7fe8b1ff1b5b971fc22) I'm getting a panic when running (load-image) for my relatively small (1-2 functions) image. 

Guru Meditation Error: Core  1 panic'ed (LoadProhibited). Exception was unhandled.

I can possibly spend some time tracking this down, but here's the associated binaries for now.

I assume you've previously saved an image?

Are you saving the image to flash memory or SD card? In other words, do you have:

#define sdcardsupport

uncommented?

incanus commented 10 months ago

Yes, a saved image was previously loading on release 3. I am using the SD card.

technoblogy commented 10 months ago

Ah, sorry, images aren't guaranteed to be compatible across releases. If there's something valuable there reload it with a copy of Release 3 and print it with pprintall.

technoblogy commented 10 months ago

I thought this was documented in the description of save-image, but I've just checked and found that it wasn't. Apologies - I'll add that.

incanus commented 10 months ago

I see it there now, thanks.
