ESP8266 FOTA crash after sumlength shown

[nvl1109]

Hi all,

I have issue about ESP07 8Mb FOTA. The same result for SDK 1.2 and 1.3.
I have tried same hardware board but use 512Kb (256Kb + 256Kb) the OTA works well.

My code to do FOTA:

Code: Select all

The apache web server access log:

Finally, here are the flash command:

Code: Select all

python esptool.py --port /dev/ttyUSB0 write_flash -fs 8m 0x00000 ../bin/boot_v1.4(b1).bin 0x81000 ../bin/upgrade/user2.1024.new.2.bin 0xFE000 ../bin/blank.bin

Do you have any idea about this problem? Thanks so much.

Hi,

Please use the ESP Flash Download Tool and select the Flash size to be 8Mbit.

Otherwise, the Flash size may be 512KB by default, and when you download firmware, it will be downloaded to the Flash space which has already stored the running firmware.

Thanks for your interest in ESP8266 !
