Thanks to Gonzo_the_great. I followed his text in #428 exactly and now have a full unlocked SSA3021X
My procedure, Analyser delivered SW1= 1.2.8.3, SW2= 2017-05-12-1, SW3=000000D1, HW=07.03.00
1) Download firmware update from siglent v 8.5a, quick format a FAT32 usb stick San Cruzer 8gb, unzip update and copy .ADS file onto mem stick.
2) Insert into SSA3021X and boot.
3) system> system info> firmware update> update (system reboots a few times etc. reboot and confirm update is correct 1.2.8.5a
4) putty, telnet>login etc.
*i tried to update and mod the files here but after backup of 2 folders and mv (rename) was tried said filesystem was read only.
5)need to power off/reboot after firmware update first.
6)follow the instructions from Gonzo.
On a unit, brought last week, with rev 8.3 firmware, we used the following script:
plug in FAT32 formatted USB memory stick (to take a backup).
telnet to SSA30xxX
root/ding1234
cd /
cp -R /usr/bin/siglent/usr/backup /usr/bin/siglent/usr/mass_storage/U-disk0/SA-backup
cp -R /usr/bin/siglent/firmdata0 /usr/bin/siglent/usr/mass_storage/U-disk0/SA-firmdata0
mount -o remount,rw /dev/ubi2_0 /usr/bin/siglent/firmdata0
cd /usr/bin/siglent/firmdata0
mv NSP_sn_bandwidth.xml NSP_sn_bandwidthx.xml
mv NSP_trends_config_info.xml NSP_trends_config_infox.xml
mv nsp_data_b nsp_data_bx
cd /usr/bin/siglent/usr/backup
mv NSP_sn_bandwidth.xml NSP_sn_bandwidthx.xml
mv NSP_trends_config_info.xml NSP_trends_config_infox.xml
mv nsp_data_b nsp_data_bx
cd /
sync
logout
reboot
Works fine. All options enabled, including bandwidth extension, permenant licences.
I'm happy!
Thanks again Gonzo_the_great.
Grump.
