dev boards w/esp-12* - Githubissues

treii28 commented 7 years ago

I just started playing around with this on an ESP-01 and an ESP-03 successfully. I want to try dropping it on one of my free 12f's this weekend. But I also have some dev-board type esp-12 modules such as the NodeMCU and the Feather Huzzah. I tried the esptool.py to program these with no success. Is there a trick to getting the firmware onto one of these boards?

Did you follow the instructions at https://github.com/jeelabs/esp-link/blob/master/FLASHING.md ?

Hi, I've been trying to make this work with a nodemcu and a wemos D1mini for about four hours now and I can't get it done. At first I just ran thee esptool.py command from https://github.com/jeelabs/esp-link/blob/master/FLASHING.md for the 4Mbyte module and it flashed with no errors, this is the output.

Leaving... Hard resetting... `

but none of the boards does nothing afterwards. Then connected GPIO0 to ground, GPIO2 to pull-up and GPIO15 to pull-down in the nodemcu as the tutorial said, and got the same flashing result. But the board still does nothing when GPIOs are connected in normal operation mode (I don't have a reset pin on my board to connect to GPIO0, its a FLIP32 autopilot).

I tried to read something in serial port using gtktem on ttyUSB0 but a could find what value of bps to use. Something shows when I push reset but it's gibberish.

I tried with versions 2.2.3 and 3.0.14.

Can someone see where did I go wrong? Thanks a lot in advance!!

i have nearly the same result with dev-board v1.

I can flash bin files and can start it BUT

after i connect TX and RX and START Dev board again, it is dead!!!! = NO WIFI, SERIAL SHOWS bootmode (3;6), but nothing happenes.

I have to REWRITE all RAM with BLANK.bin file and afterwards flash esp-link again, then i can start again to see wifi etc.. BUT if i connect RX and TX same procedure!!!! P.S.: i used connection wit a level shifter and without...same result)

What do we wrong?
