ESP8266 Community Forum

- Thu Dec 07, 2017 11:32 am #72389 I am trying to program 4 esp-01 modules I recently received.

I am currently able to program 2 Esp01s that I have been using for several months, however I am unable to program the new Esp01s with the same programming hardware.

I have tried almost every setting combination in the IDE under Generic ESP8266 Module , but the error is always:

Code: Select allerror: espcomm_upload_mem failed

this is the output from the debug window:

Code: Select allWARNING: Category 'Sensor' in library Adafruit_VL53L0X is not valid. Setting to 'Uncategorized'

If I view the serial monitor output on startup at 74880 Baud I see:

I would expect the following settings to work:

QIO flash mode
1M / 64k
ck reset
40MHz flash speed
80MHz cpu speed
115200 upload speed

But they have not and I have tried many combinations and variations. When the module is powered on the blue led flashes ~5-10 times randomly within 5 seconds then stops. When attempting to upload the blue led flashes a few times then stops.

The exact same programming setup works with other ESP01 modules I use so I am confused why it's not working for these new ones. This is the link to the product page:
https://www.ebay.com/itm/ESP-01S-ESP8266-ESP-01-Wireless-Transceiver-Module-Breakout-Breadboard-Adapter/112221319911?ssPageName=STRK%3AMEBIDX%3AIT&var=412532827457&_trksid=p2057872.m2749.l2649

Any ideas?

- Thu Dec 07, 2017 11:44 am #72391 ok I will do it, but I don't understand why, because there are settings in the Flash Size menu for 512k, 1M, 2M, and 4M; the 1MB setting has 7 SPIFFS size options... ?

- Thu Dec 07, 2017 4:44 pm #72398 Thanks for the suggestion but this had no effect it does the same thing they will not program.

- Thu Dec 07, 2017 5:15 pm #72400 Ok I found the problem, I had a resistor between the GND pin and the RST and GPIO0 buttons. When I remove it they will upload correctly if I use the Generic ESP8266 board option with 1MB flash; the ESP01s board option you supplied is not allowing WIFI to start for some reason.
