I can't do the AURIX Firmware OTA Update.

I update Drive PX2 software with latest DriveInstall
After linux install into Tegra A/B and AURIX Flash with windows, I try AURIX OTA update from tegra A.
But it failed with error log below.

(our network submask is 255.255.252.0, and Tegra A/B, AURIX have static ip address)

Tegra A log

And I edited /etc/systemd/scripts/nv_tacp_init.sh to create proper subnet mask. update script say below.
(few minuits after this, subnet mask was returned automatically to 255.255.255.0 by other script(???))

Dear y-suzuki,

According to your log, maybe I think you need to flash new EB FW from Windows based Flasher.
Aurix is booted with old EB FW which doesn’t support Aurix OTA
Please Flash new EB FW from Windows based Flasher as provided by PDK

So could you please refer to below link and re-try to flash AURIX? Thanks.

I flashed EB FW from Windows again with DriveInstall-4_1_8_0/VibranteSDK/vibrante-t186ref-foundation/utils/scripts/DPX2-P2379-EB-V2.02.04_release.zip in DriveInstall 4.1.8.0 Linux SDK.
but OTA FW update failed again.

Dear y-suzuki,

According to FW version and your log, I think the Aurix FW has been updated to 2.02.04 already.
So you don’t need to update Aurix FW anymore. Thanks.

OK, I understand. thank you.
