SWU forwarder fails

[Michael Häner]

Hi,

I have just run into a problem with the "SWU forwarder" and do not understand the cause.

On the master device I see the following:

swupdate.sh[272]: [TRACE] : SWUPDATE running : [install_single_image] : Found installer for stream hedge-image-esdk-cxg3-5.3.0-beta.7-89-gebc6676e7e.rootfs-20240625065519.swu swuforward

On the slave device I see the following:

swupdate.sh[2123]: [ERROR] : SWUPDATE failed [0] ERROR mongoose_interface.c : ev_handler : 727 : 0xf socket error

```

The sw-description file has been extended as follows:

filename = "hedge-image-esdk-cxg3-5.3.0-beta.7-89-gebc6676e7e.rootfs-20240625065519.swu";

sha256 = "$swupdate_get_sha256(hedge-image-esdk-cxg3-5.3.0-beta.7-89-gebc6676e7e.rootfs-20240625065519.swu)";

type = "swuforward";

installed-directly = true;

properties: {

url = ["http://192.168.251.113:9990/upload"];

};

An independent test with CURL worked fine:

curl -F "file=@hedge-image-esdk-cxg3-5.3.0-beta.7-89-gebc6676e7e-dirty.rootfs-20240627052920.swu" "http://192.168.251.113:9990/upload"

Content-Type: text/plain

Connection: close

Ok, hedge-image-esdk-cxg3-5.3.0-beta.7-89-gebc6676e7e-dirty.rootfs-20240627052920.swu - 81 bytes.

Thank you for your help.

Best regards,
Michael

Hi Michael,

It seems at first glance an issue inside mongoose code, and it cannot
recover. I am afraid that without debugging on the hw where it happens,
I cannot help more.

Best regards,
Stefano Babic
