Flashnchips: "Failed to merge flash filesystem"

[fedy2]

I've flashed my ESP8266 01 a first time successfully but I got no responses from the live console.
I've decided to flash it a second time but I get the following error message "Failed to merge flash filesystem".
What I can do about?

I'm using an ESP8266 01, connected trough a FT232 adapter. Flash'n'Chips is running under Windows 7 x64.

@fedy2 I don't know what is the root cause in your situation, but let's start by disabling the merge FS feature and get your device working:

Invoke flash'n'chips from cmdline and pass --overwrite-flash-fs --gui params

Not sure if --gui is necessary on windows, I have a vague memory of windows apps having to be either console or gui (defined at link time). @gelraen knows more about it.

Yes, Windows binary doesn't print anything in the console :(

@fedy2 , can you also add --log fnc.log --V=4 and share fnc.log somehow? This may help to figure out why exactly merging fails.

Tested with logs enabled: http://pastebin.com/Tc90bLwW

With the --overwrite-flash-fs param the flash operation completed successfully.
However the device don't reply to console commands. I will open a new issue about it.

WARNING: Current flash params bytes: 0240

This doesn't sound right for ESP-01. It should be 0000. You can try to override it with --esp8266-flash-params 0x0000

[fedy2]

With the --esp8266-flash-params 0x0000 param the console works after a re-connection.
However the first message after flashing is un-readable:

--- flashed successfully

Can you try to disconnect GPIO0 from GND and reset the board?

[fedy2]

After the reset I've obtained the device id and psk. Thank you.

[mkmik]

Does it work now without the overwrite fs and/or flash params options?

[fedy2]

Nope. I have to specify both the parameters.

FNC received a lot of fixes, not sure this issue is actual (I have not seen this problem for a long time).
I'm closing issue, but feel free to reopen.
