mio crash after infinite loop

Post by ydna1979 »

after crashing my whole setup with an infinite loop function, the power led on my mio flashes red i get this at the terminal
pi@RevPi81739:~ $ piTest -d
Found 2 devices:

Address: 0 module type: 95 (0x5f) RevPi Core V1.2
Module is present
input offset: 0 length: 6
output offset: 6 length: 5

Address: 32 module type: 32886 (0x8076) RevPi MIO V0.0
Module is NOT present, data is NOT available!!!
input offset: 11 length: 34
output offset: 45 length: 27
i got the core module back up by going into pictory and chanbging some settings which unfroze node red but it seems my mio is toast. Any ideas?

Please provide more details about your setup and how your "inifinite loop" looks like. Thanks

var m = msg.payload;
var local_bag_pressure = m;
do{
// store bagpressure as a global var
global.set("bag_pressure", local_bag_pressure);
}
while (m > 0)
return msg;
The function above was meant to read from a pressure sensor and update a global variable. I obviously wrote it incorrectly. When i deployed it, node red completely bogged down into an unusable state. I was able to recover the system by deactivating the input pin for the sensor in pictory. Unfortunately, I noticed that after doing so the red power light was flashing red and i could not get a response from the mio.
