I’m attaching 2 versions (remove the .txt extension to use), the smaller one works, the larger one fails with:
S47:20.51 loader: loaded partitions.bin 0x00008116 off 278 len 00000278 (0/7914/557524 remaining)

S47:26.25 dfu: cannot update host: esp: erasing flash failed (reason #2)
S47:26.25 dfu: retry #10
My best guess at the root cause is the 2971ms timeout waiting for reply might be too short.
Although I’m noticing messages like U42:25.28 *** WARNING: LARGE ALLOCATION size:72734 remaining:593560 Which might be relevant
I’ve seen some inconsistency when reproducing this error that I can’t explain.
i.e. it does occasionally work with larger firmware.
(As per my last comment on my original topic)
Out of curiosity, I tried this with a Blues Swan host too.
It works OK with a ~920kB firmware, but I did see it fail at ~1344kB
This looks like a completely different error, but I did expect this to work given the DFU limit of 1.5MB and the flash size of 2MB

I’m looking into this now and will get back to you when we have some updates. I just wanted to confirm you’re on the latest LTS release (6.1.1) and using only the Notecard WiFi v2?
