...but if I could repro it, doesn't this look relevant?

So it turns out I can't reliably repro the situation where it's trying to write outside the allocated area. Today it's hardfaulting much earlier and hitting the same "Backends flushed" warning logging that I was seeing earlier. I've opened private case 237487 for that. That seems to now be blocking me from repro'ing this issue, sorry. Could we have a look at that one first? Thanks.

Hi Eliot,

I have not seen this, but the backend should obviously not attempt to write outside of the allocated flash area. As a test, could you comment out the assert check and see if it continues to fill the flash page at 0x50000, or if it stops after the last 12 bytes?

Thanks.

Hi Vidar. I'm just picking this up again now, having re-enabled the flashlog. The flashlog is trying to write 12 bytes at destination 0x0050000, which is outside the range 0x0004F000 to 0x0004FFFF.

Here's where I'm guessing the flashlog is in flash:

Why it's trying to write to 0x0050000, I have no idea.

Hi,

The error indicates that you're trying to write to an invalid address. Please check if the "dest" address passed to addr_is_within_bounds() is in the p_fs->start_addr to p_fs->end_addr range.
