7i96 Error finishing read.

No it has ST 25p16vp chips.
however as soon as I can I try to heat it up a little and try again, but I'm sure that once started it works regularly.

Thanks Peter, what is a bad ping limit do you think?
5V Power was a small caged power supply connected to TB2. Would it be better to connect to the dedicated P3 connector?

Its not the flash memory that has the problem, but rather the Ethernet EEPROM (93C46)
 

Its not likely a power issue unless running on a somewhat sketchy supply like
a USB cable.

I would want tun run the servo thread at about 2X the largest servo thread tmax
(converted to ns)

view itself is a 93c46b. I can make a copy and put a more reliable chip like the new ones maybe if you tell me the type I can mount. i can do it i have already replaced and copied eeprom of televisions.
Thank you

Pcw could you tell me which chip to put in place of the 93c46?
Thank you

That is the correct chip, its just that MicroChip parts are unreliable
at low temperatures. ST M93C46WNM6TP chips have been 100% reliable
at -40 to +85C

Available I found this ST  m93c46-rmn3tp/k
 in the automotive class -40 + 125C
otherwise the one you said in May. it is not urgent now I have put the 5i23.

Not relevant, but I chilled a car down to -40C overnight this week, and it started with no obvious chip failures.

To check for timed out packets, look at the tmax values:

halcmd show param *.tmax

These are in units of CPU clocks

 
 

So we got this. I'm not sure what CPU clocks is on an i5
 

Is this bad?
