Super Watchdog Interrupt

Hi Alex
The Command line utilities work great on the UPS Card. The Python Utilities work great from Python Fantastic work
The command line wdt -h reveals a command wdt -bint. There is no command to query this feature if is enabled or disabled
Testing has revealed that wdt -bint 0 disables the button mounted on the side (in the same location as all other cards) of the wdt card This was tested via a python script polling the button on the card & found the button was non operational. wdt -bint 1 Enabled this button again confirmed via python script. The function is great & very usable for a headless reset restart. " Excellent " however documentation does not quite line up with this Don't really care was able to work out.

Biggest problem is the Interrupt line from the sequent WDT Ups card is holding the interrupt line & not releasing this line therefore & not allowing any sequent card that i have installed able to change the interrupt line RPI 40 pin connector Pin 37 GPIO26. There appears to be no way of turning this feature on or off from either the Command line or from within Python
Every other feature of this card Excellent

Please Help is it possible to get an additional command line command to Enable/Disable the Interrupt line so as enable other cards to use the interrupt line.

Regards TonyD

Hi Tony,

We will update the documentation, thank you for the suggestion.
Could you tell me the card version so I can dig into this interrupt problem?
If there is a bug here, it will be solved only with a new firmware version but except for the V9.x it needs to be made with an STLink probe

Unfortunately, if I find the bug, you need to reflash the microcontroller using STLink and hook some wires on the 2x4 pin header .
Give me a few days to start debugging this.

Sorry to Bug you again
You Mention earlier that V9.x WDT Super Watchdog.
Is this V9.x card available if so would like to purchase how do i go about getting this version & don't worry about firmware update will throw WDT card on another system not using Interrupt

The V9.0 will be available in a few days, I will let you know when we receive them. It contains probably the same bug but is easy fix.
We also do some hardware improvements, starting with a better charger, dual input voltage options 5V or 10 - 24V, and breakable PCB for use with one or two batteries.

The card can be powered from 24V but the output voltage and maintained by the battery is 5V. We added a switching power supply that converts 24V into 5V.

Hi Alex
with the release of the new v9.0 card love it by the way especially the 24VDC powering the card now i can do away with the 24VDC to 5VDC power supply
Is there any further movement on the fix with the interrupt line as mentioned above in this thread by this card not releasing the interrupt line
I will be trying out the new card in the live system in the next couple of days but suspect it will be the same problem . Will let you know the outcome
If you do update the firmware for the card could you please include a firmware UPDATE program for 64bit linux which is what i am running on the RPi5

Is it also possible to query the interrupt line Enable/Disabled from command line wdt -g bint. Note Have found that this is already in the firmware just not documented in the list when doing wdt -h -g

As well as being able to Enable/Disable the WDT interrupt from the command line is it possible to include this Enable/Disable from Python as well & a linux 64bit firmware UPDATE programme for the new WDT v9 card with a caveat that the UPDATE program will not work with earlier versions

Further testing enabling command line push button wdt -pbs 1 & query wdt -g pbs shows the push button enable however depressing the push button & then querying from the command line wdt -g pbs shows 0 was expecting a 1 after depress The above procedure after a time delay (which iam not sure where this time delay comes from) puts the WDT & RPi5 into a continuous shutdown reboot process that once enabled can only be halted by removing batteries & power.
The only cards fitted to the RPi5 are NVME SSD card, RPi5, 16relind solid state Sequent Card & new v9 WDT card


The reason for all of this is i was trying to enable an Interrupt driven orderly wdt interrupt headless shutdown & or Display card interrupt driven Button or Rotary nob scanning routine hence the need for interrupts from WDT & Display Card.


Regards Tony

Hi Tony,

I am planning to work on the firmware/drivers of the Watchdog next week and I will try to address all your requests. I will keep you posted.

Alex.
