  • Yeah, I tried all of those things. I’ve tried it with the latest stable esp8266 Arduino, and the latest esptool-ck (which happens to be the same one that is included with the esp8266 Arduino).

    I’ve now tried it with 4 or 5 boards and both using Arduino and manually and get the same output:

    esptool-ck  -vvv -cd ck -cb 115200 -cp /dev/cu.usbserial-DA01R6ZH -ca 0x00000 -cf /var/folders/l9/mgv_83hx22g9lrmsx1cnwg4w0000gn/T/build3564637723258270712.tmp/ESP8266_Standalone.cpp.bin

    We have a workshop with 25 of these tomorrow morning and we’re kind of up a creek without a paddle at the moment. I’ve contacted the support team several times over the last few days via email on via the web form with no response.

  • For what it’s worth, if I manually take GPIO0 to ground on startup, it will enter bootloader mode and I can program it via the integrated FTDI/USB cable.

    Is this normal or should the integrated FTDI/USB be taking GPIO0 low automatically w/DTS … ?

  • Hi there, just received the new WRL-13711 board and am unable to upload a program using Arduino or the standard esptool / espressif sdk. I have been working with the older WRL-13231 (and generic ESP8266s) and am able to upload programs using an FTDI breakout.

    So here’s what I know:

    • The FTDI device shows up and I can connect to whatever program was shipped with the unit (confirmed with CoolTerm, screen, etc).
    • When uploading there are three groups of three blinks on the RX led of the WRL-13711. This is the same pattern I see when initiating an upload on the WRL-13231, so I believe the FTDI is communicating correctly.
    • I’ve tested several USB cables in an attempt to confirm that isn’t the problem. Each exhibits the same blinks.
    • In the past when the esptool failed, I powered off the device, unplugged and replugged the usb, and tried slower communication speeds and the WRL-13231 would eventually accept a program. No combination of speeds, unplugging and replugging, power-cycling, etc has worked thus far.
    • I’ve tested this on two units so far and both seem to have the same problem. I’ve got 20+ other units that I could test, but imagine it’s probably the same issue.
    • To my eye, the blink pattern and fail looks like the situation that happens when the board is not put into bootloader mode. On the WRL-13231 this was done via DTR – not sure how it’s working on the DEV board, but haven’t looked at it too closely yet. Perhaps the board is not going into bootloader mode successfully? Anyway I scoured the hookup guide (of course … it’s quite possible that I missed it), but I didn’t find any special instructions for manually placing the device in bootloader mode.

    Thanks! Christopher
