@igrr what address range should I do read_flash on?
Sketch uses 207,276 bytes (19%) of program storage space. Maximum is 1,044,464 bytes.
Global variables use 44,816 bytes (54%) of dynamic memory, leaving 37,104 bytes for local variables. Maximum is 81,920 bytes.

@igrr
address 0, size should be the size of the uploaded bin
207276 bytes
Victor Aprea
@vicatcu
k that's
what i thougth
can't just diff on binary files though right?
@igrr well the file sizes differ, which I guess is interesting for a start
Ivan Grokhotkov
@igrr
perhaps esptool.py doesn't know how to read sizes which are not multiple of 4 bytes?
Victor Aprea
@vicatcu
no it's the compiled bin ...
i need to turn the elf into a bin or something right?
Ivan Grokhotkov
@igrr
oh, darn, you're right. it's the size being reported by the IDE which is off the mark :)
Victor Aprea
@vicatcu
rather than just grabbing the bin file from home/vic/.arduino15/packages/esp8266/hardware/esp8266/1.6.5-947-g39819f0/bootloaders/eboot/eboot.elf -bo /tmp/build6389748398816362263.tmp/sketch_oct05b.cpp.bin -bm dio -bf 40 -bz 2M -bs .text -bp 4096 -ec -eo /tmp/build6389748398816362263.tmp/sketch_oct05b.cpp.elf -bs .irom0.text -bs .text -bs .data -bs .rodata -bc -ec
the bin there is 211424 bytes
Ivan Grokhotkov
@igrr
it doesn't account for the sector which contains eboot, and some additional padding
so you should read 211424. sorry, forgot about that...
Victor Aprea
@vicatcu
python esptool.py -p /dev/ttyUSB0 read_flash 0x00 211424 download.sketch.bin
ya?
Ivan Grokhotkov
@igrr
yep
you can do hexdump and the diff hexdumped bins
Victor Aprea
@vicatcu
ah ok one sec
files are identical
is the bootloader ROM actually a ROM or could it have been corrupted?
and if it's corrupted can it be restored?
Ivan Grokhotkov
@igrr
It's a mask rom, and looking at serial output, it appears to work.
Victor Aprea
@vicatcu
i'm not sure what to make of the fact that I can't seem to see the bootloader output now though
i think i was in windows when i was seeing it before
a little hard to believe that would matter... but
i'll reboot and check it out in windows again
brb
Victor Aprea
@vicatcu
what the hell, i see output in windows @ 77600
Ivan Grokhotkov
@igrr
might be a driver-related difference
Victor Aprea
@vicatcu

anyway, ya

ets Jan 8 2013,rst cause:2, boot mode:(3,6)

what's the 6 part of (3,6) telling me?
the rst cause: 2 is strange because there is no activity on the reset line either
it is pegged high
how about the flash_id... is that actually reading it out of from spi flash, or is that in memory somewhere
Victor Aprea
@vicatcu
@igrr i have a feeling we're just going to call it an unsolved ESD mystery and move on... hehe
Ivan Grokhotkov
@igrr
might be the right thing to do, in terms of time spent :)

@tullo-x86
Hi all, is this an appropriate place to ask questions about usage? I'm trying to figure out if the Arduino <SPI.h> header is what I need to use to get SPI output working.
Victor Aprea
@vicatcu
yea i only care if it's a thing that happens more than once
@igrr what country are you in btw?
Ivan Grokhotkov
@igrr
Russia, Saint-Petersburg

that's what i thought, you're a night owl :)

i'm in upstate new york
lol
@igrr well let me just say you are doing great with this project
and thank you
i'm still curious what the 6 means in boot mode: (3,6) if anyone knows
