[Solved] Problem flashing ESP (12E) with 4096k ESP Easy

[groovy]

I'm facing a strange problem with my ESP 12E boards when using ESP Easy 4096k version.

Flashing itself succeeds, but after reboot, there is no AP called ESP_0, but an AP called something like ESP_FDBCF4, where the last 6 chars are the last 6 chars of the MAC address.
I can connect to that AP (there's no WPA key neccessary), and I even get an IP address (192.168.4.2) and can ping the device at 192.168.4.1.
But I can't open the web interface.

However, when I use a 512k image, I can see an AP named ESP_0, get an IP address and can successfully open the web interface in the browser and configure that device.
At the Main page, I can see that the "Flash Size" is indeed 4096k.

I tried several ESP 12E modules, all with the same behaviour. It also doesn't make a difference if I use a precompiled image or compile it myself.

Has someone any idea, what's wrong here?
Will I be able to use the 4096k displayed at the Main page, even if I used a 512k image?

Thanks in advance.

I have faced exactly the same issue. I don't know what exactly is causing it but the way I "solved" it is by using a pc with wifi rather than a phone or a tablet. Even when I connected via pc, it didn't ask me for the initial "configesp" password, just went straight to the ssid/pass page. I am interested in knowing about this as well.

Thank you for your reply. Unfortunately, trying to connect with a PC doesn't work for me, I get a "connection refused".
I also tried scanning the device with nmap. It tells me that there is no port open at all:

Have you tried serial terminal to see what it is doing?

[groovy]

I just tried again with the actual git version. Serial console gives this at boot, so there is definitely something wrong:

I used this command to flash:

Code: Select all

python2 ../../esp8266/esptool-master/esptool.py --port /dev/ttyUSB0 write_flash 0x00000 ESPEasy.ino.generic.bin 
Connecting...
Erasing flash...
Writing at 0x00068800... (100 %)

Leaving...

Any idea? Do I have to use another address to flash to? I used 0x00000, which works for my ESP-01 modules.

[groovy]

Just investigated a bit further. When I add parameters explicit for flash-mode and flash-size, it works. Command then looks like this:

Code: Select all

python2 ../../esp8266/esptool-master/esptool.py --port /dev/ttyUSB0 write_flash -fm dio -fs 32m 0x00000 ESPEasy.ino.generic.bin
