Problem with flashInit

[ederjdi]

I would like an information if possible about the sming. I programmed it in the first version of Sming and it worked perfectly, I downloaded version 3.7.0 and now from 3.7.1 when I write the program as blink the basic_wifi works perfectly. But when I burn files that have html the "esp" does not start I tested with the httpServer_configNetwork. This software does not show the network. What could it be? I downloaded the site I unzipped got the mingw files all ok my "ESP" is esp-01, it's some configuration I have to do.

How do flashInit occurs the error of

Remembering that I always clean and then everything And to record the GPIO 0 is in GND The model is ESP01 I am using sming on windows in eclipse Thank you very much for your attention.

Looking at the excerpt above I guess you should execute the following commands one after the other. And in between you must make sure that the device is in FLASH mode. The easiest way to do this is to set the correct pins and power off and power on the device. Try the following sequence:

; make sure that your ESP01 device is in FLASH mode.

/c/Espressif/utils/ESP8266/esptool.exe -p COM4 -b 115200 erase_flash

; after success power off and then power of the device. 
; If you haven't touch anything else your ESP01 should be in FLASH mode already. 
; If not, make sure to put it in FLASH mode.

/c/Espressif/utils/ESP8266/esptool.exe -p COM4 -b 115200 write_flash -ff 40m -fm qio -fs 4m 0x7c000 /c/Espressif/ESP8266_SDK/bin/esp_init_data_default.bin 0x4b000 /c/Espressif/ESP8266_SDK/bin/blank.bin 0x100000 /c/tools/Sming/Sming/compiler/data/blankfs.bin

Also check if your flash size is set correctly. The command above shows me that your flash size is 512 KB. Is that correct? Or you have 256 KB?
