Support request: Error writing filesystem image for ESP8266

[PaulWieland]

I'm trying to setup ESP Web Tools to write a two part (firmware and file system) to an ESP8266.

The first ratgdo_esp8266_v2.0a.bin file at offset 0 seems to write okay, but then it times out right after it starts to write the second ratgdo_esp8266_v2.0a_littlefs.bin (~3mb) file at offset 1048576.

I got the offset number from platform.io when uploading the filesystem:

Wrote 3121152 bytes (679027 compressed) at 0x00100000 in 74.9 seconds (effective 333.3 kbit/s)...

0x00100000 in decimal is 1048576

Here is the output of the browser console during the flashing process:

Writing at 0x48000... (100%)
flash_defl_block 8d 097
check_command write compressed data to flash after seq 18

Does anyone know what I'm doing wrong?

UPDATE:

From the log you can see that the step Writing at 0x104000... (4%) is where it times out. In platformio, this step takes longer than the rest, but it does continue. How can I increase the Read with timeout value?

I am also facing the timeout issue, while writing spiffs.bin to esp32.

[PaulWieland]

I wish I could get some support on this. I can't figure out how to modify the read with timeout value, or even where in the source code that it's set.

@PaulWieland did you get this resolved?

[PaulWieland]

No, unfortunately not.

Anyone, any suggestions?

Using latest Version? Changes are done in used esptool.js regarding timeouts.

What is the specific device you are having this issue with?

I ask, as I've had the latest Lolin D1 Mini v4.0.0 devices fail, where earlier versions (v3.x, with the Micro USB connectors) succeed. Interestingly, this failure occurs both with ESP Web Tools as well as with older esptool versions, but seems to succeed with the latest esptool.py.
