B4R Question ESP8266 (ESP07) - OTA - not enough memory

petr4ppc · Oct 3, 2019

Dear friends, please

I get in LOGS:

Original AP IP: 192.167.4.2
Local IP: 192.168.3.15
UniqueID: 15556121
EEPROM Size: 1024
FlasfID: 1335390
FlahsSize: 1048576
FlashSpeed: 40000000
CPU Speed MHz: 80
Program Size: 417840
Free Space: 81920
CycleCount: 665793615
HeapSpace: 28160
MAC: 14F4EBEDFA39

and when I start OTA I get:

Error2: -100 Not Enough space

My src.ino.bin file have: 417840

Is here way how to download this file and - how to do OTA process?

Please for advice,

All the generated files are available under the Objects folder.

Are you able to install smaller programs with OTA? Are you able to install this program without OTA?

I have not tried smaller version of program. It is basic - simple program only with libraries (OTA, SoftwareSerial,Wifi),
but it can not be processed by OTA. With Wemos D it is OK, but with ESP07 it is NOT OK because of space.

I have in ESP8266:
Program Size: 417840
FlashSize: 1048576

It is possible to say please - How many percent of memory must program have for successful processing with OTA?
Best regards

I don't know. Sorry. Test it with a smaller program.

Are you sure you have selected the correct flash size in the B4R Menu ?

Hello petr4ppc,

you can load the example "CheckFlashConfig" an flash this on the ESP.
You get the right FlashSize.
I think your Flash Mode should be: DOUT by the ESP07.
