2.1.1 - Error 2 on flashing the firmware (Wemos D1) #153

Hello,

I have an issue similar to https://github.com/platformio/platform-espressif8266/issues/149, namely that I can't upload firmware to a Wemos D1 mini anymore, after upgrading.

Checking size .pioenvs/d1_mini/firmware.elf Memory Usage -> http://bit.ly/pio-memory-usage DATA: [==== ] 35.9% (used 29436 bytes from 81920 bytes) PROGRAM: [==== ] 38.4% (used 401576 bytes from 1044464 bytes) Creating BIN file ".pioenvs/d1_mini/firmware.bin" using ".pioenvs/d1_mini/firmware.elf" Configuring upload protocol... AVAILABLE: espota, esptool CURRENT: upload_protocol = esptool Looking for upload port...

Running stub... Stub running... Changing baud rate to 921600 Changed. Configuring flash size...

A fatal error occurred: Invalid head of packet (0xE0) *** [upload] Error 2

If I manually change the upload_speed in platformio.ini to: upload_speed = 115200 then I get a successful upload:

Uploading stub... Running stub... Stub running... Configuring flash size... Auto-detected Flash size: 4MB Compressed 405728 bytes to 294493... Wrote 405728 bytes (294493 compressed) at 0x00000000 in 28.6 seconds (effective 113.4 kbit/s)... Hash of data verified.

Leaving... Hard resetting via RTS pin...

My toolchain is the current toolchain (2.1.1)

So I just noticed there was an update released a few minutes ago. I have updated my toolchain:

Updating espressif8266 @ 2.2.0 [Up-to-date] Updating tool-esptoolpy @ 1.20600.0 [Up-to-date] Updating tool-mkspiffs @ 1.200.0 [Up-to-date] Updating tool-esptool @ 1.413.0 [Up-to-date] Updating framework-arduinoespressif8266 @ 2.20502.0 [Up-to-date] Updating toolchain-xtensa @ 2.40802.190218 [Up-to-date]

But the firmware uploading issue persists

Can I ask why 115200 was picked? As noted in both the arduino-esp8266 PR changing to esptool.py, and the esptool repo, 460800 seemed to be a reliable default, until they can work out why 921600 doesn't work (but 1000000 does).

115200 is too slow! minimum should be 460800 as in line with Arduino library. esp-tool is already in version 3.0
