#76552 I'm trying to run micropython on my esp8266, I had 1Mb of flash and replaced it with 16Mb (w25q128). I was trying to upload firmware (my custom build or stable version from micropython's site) with esptool and pyflasher. I got no errors and the validation passed correctly, but when I launch serial terminal I see unreadable characters. Also I tried to change baud rate, undortunately it ddidn't solve my problem. REPL also haven't started. What could it be?

I have read many topics how to install micropython on 16 Mb and followed the instruction, but it also didn't help.
