- Thu Feb 02, 2017 10:04 am #61917 I'm using the official unofficial ESP DevKit in Eclipse and the makefiles use esptool to flash the target system, which is a Nodemcu type board.

Has been working great, but I recently got a new shipment of boards and half of them won't flash using the same environment. They seem to flash just fine, but they become stuck in a boot loop trying to run the program:

Code: Select all...
ets Jan  8 2013,rst cause:2, boot mode:(3,6)

load 0x40100000, len 27332, room 16
tail 4
chksum 0x07
load 0x3ffe8000, len 884, room 4
tail 0
chksum 0x8d
load 0x3ffe8380, len 348, room 8
tail 4
chksum 0x60
csum 0x60
 ...

So, they are the exact same type of boards, mixed 12e and 12f. Most of the 12f don't work, most of the 12e work, with a few exceptions. They seem to be flashing OK in other flashers. I have tried tweaking the make options to no avail; APP, SPI_SPEED, SPI_MODE. What's going on?

Update:

Tried the newest esptool.py in dio mode: Same thing except it hard resets at the end:

- Sun Mar 19, 2017 10:47 am #63944 Did you ever get anyplace with this issue? I am having the same issue with -01's. They all program textbook perfect, but some of them come up with that same string of goo that ends with the RF Cal Sector. The exact same flash is working on other boards from the same lot, and I run the erase flash on all of these before I program them.

This problem seems to only pop up with firmware from the custom build site, and I have built a few different bins, including the int version of 1.5.4.1-final-7-modules and the latest main with 7 modules. All of the modules will program and run fine with the old nodemcu_integer_0.9.6-dev bin.

I thought I had a pretty firm handle on flashing custom builds on these modules but I am back to having issues again.

I am using esptool.py to flash them..

- Sun Mar 19, 2017 1:38 pm #63956 No, no amout of flashing them in other ways make them work with esptool(.exe). They do however seem to flash fine in Platformio.
