Maximum sketch upload speed

[cmburns]

Hi,

I use sloeber now and created my first sketch (blink) for my ESP8266 (ESP-07, 1MByte Flash).
It worked fine with upload speed 115200.

But if I change upload speed (under project properties-->Arduino Board Selection) to 921600 then I get following error in console view:

warning: espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed

If I switch back again to 115200 then I can upload the sketch without problems.

In console window I can see:

Launching: C:\ProgramsMB\sloeber\arduinoPlugin\packages\esp8266\tools\esptool\2.5.0-3-20ed2b9/esptool.exe -cd ck -cb 921600 -cp COM3 -ca 0x00000 -cf C:\sloeber_workspace\ESP07_Test1/Release/ESP07_Test1.bin

My question now is what is the max. upload speed for my ESP8266 (ESP-07)?
How can I make speed 921600 working?

My sloeber version:

Sloeber, the Eclipse Arduino IDE (plugin version) 4.3.1.201810100607 io.sloeber.feature.feature.group Sloeber.io

For flashing I use an FTDI adaptor with FTDI chip

FTDI
1230-C
GO171471
F232RL

Thanks for any help

Why do you think this is a sloeber issue?

My question now is what is the max. upload speed for my ESP8266 (ESP-07)?

This question is somehow related to this discussion[1] - and totally unrelated to Sloeber.

Please close the issue.
