I spent most of my time fixing APIX2. However, since I've had to order a new panel for that screen, I decided to look into making this ID3 screen I have here work with my NBTevo_Y23236I on HW2.3.

It's actually quite simple. It seems that HUJacintoStage1 now enforces voltage monitoring. The developers were kind enough to add a flag that disables said enforcement. All that has to be done is to create a file:

On the Jacinto side (serial/telnet/ssh):

Code:
touch /var/opt/sys/APIX_VMON_OFF && \
sleep 5 && OnOffDSICommander appreset

Alternatively from OMAP:

Code:
on -f hu-jacinto touch /var/opt/sys/APIX_VMON_OFF && \
sleep 5 && OnOffDSICommander appreset

After this the screen should turn on. After clearing DTCs, CID errors should not return.

Tested with HU 6829104 on NBTevo_Y23236I and CID 9252004.
