the 3.3V voltage regulator on the base board is controlled by the 3.3V output of the PicoCore.
The PicoCore PMIC disables the 3.3V on the PicoCore during reset and the 3.3V on the base board is switched off.
But if voltage from the base board is fed…

We have updated our OSM design data library!
It now contains information for Cadence(R) and ALTIUM^(R).

1. Schematic

• Cadence library (fs_osm.olb) including:
  • general OSM symbol (V1.1, V1.2, size S)
  • symbols of F&S OSM modules (module-specific

Hello,
here is CPU/Board info of one of the modules (MAC 00:05:51:1A:A4:BC):
CPU: Freescale i.MX6SX rev1.4, 996 MHz (running at 792 MHz)
CPU: Extended Commercial temperature grade (-20C to 105C)
Reset: POR
Board: PicoCOMA9X Rev 1.20 (LAN, 1x DRAM)
…

So I tried the same setup with an external pull-up with the PicoCoreBBDSI and it behaved the same...
I then took a look at the behaviour of a GPIO without any external connections and found something interesting:

Setup:
PicoCoreBBDSI (v1.4) +…

A software partition is only required for boards that boot from eMMC, like the PicoCoreMX6UL. However, the PicoCOMA7 boots from NAND. So no partition is required, only MTD-partitions are necessary there, but they are completely handled in U-Boot. So…

Hello,

we have run an ethernet test over the weekend and it still worked after 60 hours. Do you have any new insights?

I have a problem creating a partition on a PicoCOMA7.
I'm trying to install Linux on it, but I can't seem te get this to work
The option for creating partitions is just not available it seems.
When i press (lowercase) w it does nothing.

Is there a way to…

The PMIC of the PicoCore disables the voltages at reset. Depending on the extenal wiring of the PicoCore it is possible, that current is fed back to the PicoCore from the baseboard. Then the voltage is never shut off completly.
You can send the…

Hello Kamil,

thank you for reaching out. can you please provide us your boards revision and the software version you are using? We will take a look at your problem.

Hello there,

we use the PicoCoreMX8MM and we use one GPIO to be able to reset another MCU on the board.
Now we have realised that everytime the PicoCore reboots, the MCU also resets, which means the GPIO line triggers the reset.

This is our setup…
