Hello

I am using a Nucleo F103 RB with XNUCLEO-IDW01M1

board to develop the code.

I have been successfully using the Update over the air feature for some time.

I now have an image file that has grown because of the extra features on the Web pages etc

From my console I get the following message :-

<TX> at+s.httpdfsupdate=192.168.0.12,/outfile.img

<RX> Invalid HTTPD_FS image, length (633215)

I am not sure if my image file is somehow corrupt or just too large.

My previous image files have worked perfectly from a PC set up as web server

and are approx 300k in length.

I have tried running Httpd_gen.exe a few times but the same results.

Is there a maximum size permitted ?

Hi Paul,

1Mb flash memory is splitted in 2 different parts: half dedicated to FW-OTA, and half dedicated to FS-OTA. So, 500Kb is maximum allowed size for both commands.

Ciao
