After many hours of successfully flashing code I've run into a problem.

Here's the error, then a little context. I think my multimeter probes touched just before this started happening. I'm running power through it to watch power consumption.

I've tried reflashing everything but I still get the same.

Code: Select all

esptool32 --port /dev/XBeeX --baud 230400 write_flash -fs 2m 0x0000 ../../bin/boot.bin 0x04000 bin/irom1.bin 0x40000 bin/irom0_flash.bin 0xFE000 ../../bin/blank.bin

hi
not sure , but have a try in this:
think you have a 1Mb flash - just in time because actually [1] Linux esptool not support 1Mb ( [2] window flash tool supports 1MB )

you can not set
but try to set the blank.bin for your 1 Mb at 0xFC000 instead of 0xFE000 (0xFE000 is the right for 2MB )
so test :
btw,
in beta tests i allways flash with 115200 at ESP31B/ESP32

let know how you can get on in this.

best wishes
rudi

I made a little progress this morning.

Changing the blank.bin address from 0xFE000 to 0xFC000 does not seem to have helped,
but dropping -fs and letting esptool32 default to 4m helped some what. It now progresses
to "jump to run addr @ 0x40000" but is back to the problem in my post of the same title.

No more progress but there is a clear distinction between using -fs 2m/4m.

If I do not include -fs or use -fs 4m (same thing) I get stuck at "jump to run addr @ 0x40000"

If I use -fs 2m I get there "user code done" message.
