i am having a weird issue trying to use uPython on this esp8266MOD board. after flashing the firmware to the board, the wifi activity light just constantly blinks, and when i try to open up the REPL via picocom, all i get is a bunch of garbage output that just keeps going and going.
some info:
1.) i have tried both the esp8266-20190529-v1.11.bin and this one esp8266-20190125-v1.10.bin.
2.) i am uploading via the built in USB connection that is controlled by Cygnal Integrated Products, Inc. CP2102/CP2109.
3.) i am on Ubuntu 18.04.3.
4.) this is the command that i am using to upload the firmware:
Code: Select all
esptoo --chip esp8266 --port /dev/ttyUSB0 --baud 460800 write_flash 0x1000 <then the firmware file>l
I have also tried this command:
Code: Select all
esptool --port /dev/ttyUSB0 --baud 460800 write_flash --flash_size=detect 0 <then the firmware>
If there is any more info that i could provide that would be of any use to anyone, please let me know.
I also want to point out again that this is literally my first coding language, and i have little (even though i have done a few simple projects by following directions) experience with Arduino's or other micro controllers. Although i have tons of them. So what may seem obvious to you, will probably not be to me, so if you could, pleeeaaassseee point it out to me, so that i can learn
