csum err when using 1.6.4, everything fine when using 1.6.1

[drnokill]

Hello, when upgrading to 1.6.4 my ESP 8266-07 does no longer start. I'm running Windows 8.1 Pro (64 Bit) with Visual Studio 2013 Professional and Visual Micro. Using the Adruino IDE has the same effect.

When switching back to 1.6.1 (using esptool) it runs. I'm using an ESP8266-07 Board with a 25Q40BT Flash-Chip. I already tried all Flash Settings in the Board-Options

I also get

So far it looks like programming was successful. But when I then try to run the app, I get

 ets Jan  8 2013,rst cause:1, boot mode:(3,6)

csum 0xef
csum err
ets_main.c 

This cannot be be seen in the Arduino GUI but, e.g., using ESPlorer on the Mac set to 74880 bits/s and booting without pulling GPIO0 low (which was used for programming).

On one of my modules (ESP-12) I always get

tail 8
chksum 0xef
csum 0xef
csum err
ets_main.c 

I checked my setup and using an ESP-01 instead I do not get this error. Can this have to do with a different flash chip? Using esptool.py, writing to the ESP-12 and reading back the binary from the ESP-12 results in identical files, so I assume the flash is working properly.

I also tried with "NodeMCU 0.9 (ESP-12 Module)" but it still shows the csum err. Is there anything I could test? (By the way, I did not check with 1.6.1 - should I do this?)

[probonopd]

Using esptool.py I checked the flash chip of my ESP-12:

Manufacturer: c8
Device: 4016

I found on the net that this is a GigaDevice GD25Q32, so it is a 4Mbyte=32Mbit flash. Hence I tried to set the board in the IDE to "NodeMCU 1.0 (ESP-12E Module)" (because I see in the boards.txt that it uses nodemcuv2.build.flash_mode=dio).

This time I get:

load 0x4010f000, len 1464, room 16 
tail 8
chksum 0x7a
csum 0x7a
e

At least no csum err this time. So I guess my ESP-12 board is just not supported yet?

please retry in last release, If it still a problem feel free to reopen.
