Hi all,

I'm trying to set MTU to 9000 (jumbo frames) when using Basler acA2000

GigE camera with aravigGigE AD module in GIT.

Under Linux I've set network MTU to 9000. Then I used the arv-tool-0.4

tool to set the camera MTU to 9000.

hinkokocevar@hinkocmbp:~$ arv-tool-0.4 control GevSCPSPacketSize
Basler-21729661
GevSCPSPacketSize = 1500 (min:220;max:16404)
hinkokocevar@hinkocmbp:~$ arv-tool-0.4 control GevSCPSPacketSize=9000
Basler-21729661
GevSCPSPacketSize = 9000 (min:220;max:16404)
hinkokocevar@hinkocmbp:~$ arv-tool-0.4 control GevSCPSPacketSize
Basler-21729661
GevSCPSPacketSize = 9000 (min:220;max:16404)

I can acquire images using arv-camera-test from the aravis package and

the output suggests that MTU 9000 is respected:

hinkokocevar@hinkocmbp:~$ arv-camera-test
Looking for the first available camera

(lt-arv-camera-test:13489): GLib-GIO-CRITICAL **:

g_inet_address_new_from_string: assertion 'string != NULL' failed

vendor name           = Basler

gv n_stream channels  = 1
gv current channel    = 0

gv packet size        = 9000 bytes
Frame rate = 40 Hz
Frame rate = 24 Hz
Frame rate = 24 Hz
Frame rate = 24 Hz
Frame rate = 25 Hz

Under aravisGigE I'm using generated feature OPI to access the

13ARV1:cam1:GevSCPSPacketSiz PV that initially holds 1500. Setting it to

9000 works, and I can confirm with arv-tool-0.4 at this point that

camera is using MTU 9000.

When stating the acquisition IOC console is flooded with messages:

Bad frame status: 2 size: 2211840
Bad frame status: 2 size: 2211840
Bad frame status: 2 size: 2211840
Bad frame status: 2 size: 2211840
Bad frame status: 2 size: 2211840
Bad frame status: 2 size: 2211840

Any hints on what might be the problem?

Thank you,

Hinko
