Hello,

love what you're doing for the Turing Pi. I've followed your script and circuit for the power button and led on my mini-ITX case and love it.

My issue is that:

Node #3 (Worker 2)

0x08

doesn't appear to be the address to cut the power from Node #3

and I don't know how to find the correct address/register

I've stumbled upon:
https://docs.turingpi.com/cluster-management-bus-i2c
and used
sudo i2cset -m 0xfc -y 1 0x57 0xf2 0x00
and still no power changes to Node #3 (Worker 2)
ping still returns bytes and it can be logged into via ssh.

perhaps hardware bug?

or I saw this warning by nicholaswilde:
⚠️ WARNING:The register which controls the power to each board is backed by an EEPROM. Don't set all bits in there to 0, otherwise you won't be able to boot and correct it. A fix is to set register 0xF4 to 1 which would send the writes to the shadow SRAM, instead of the EEPROM. A fix for this is to connect an external raspberry pi to the I2C External pins and reset the registers.

anything I can troubleshoot about if that's the problem?
I'd appreciate whatever direction to a solution you could offer.

thank you,
-Dan
