Is it just me having this problem? I tried to flash the single file firmware (nodemcu-latest.bin from prebuilt directory) to ESP8266-201 board using nodemcu-flasher. It's always fails at some point saying flash write timeout. I did some more study on the flashing protocol (based on information from this page https://github.com/themadinventor/esptool), wrote my own flasher tool to dump the progress and noticed it failed at block 0xB700. Further more study on the image format, I realized that 0xB700 is the actual total size of first part of the image. So the module I have is actually looking for that information and refuse to flash region between 0xB700 to 0x10000. I tried a different image and confirmed that.

Is that just me running into this issue? All my two 201 modules are having the same behavior.

I too seem to have the same issue, but I have no mean to verify at what address block the update times out .
Error:Write flash timeout. at around 10% of completion. Have you found what could cause this?
