Hi,

Any chance you can send me the wiring diagram?
I am using the same in my design but cannon make it work.

Thanks,

I found some documentation about this pin in the data sheet for the AR9331.
--- quote---
7.5 Power On Sequence
The AR9331 has an internal power on circuit
reset. when all power inputs, including
VDD33, VDD12 and VDD25, are ready, the
RESET_L signal; will be released from low to
high. This signal is connected to a digital
counter which controls the digital reset and is
released after 5 μs. When the digital reset goes
from low to high, the CPU begins fetching
instructions from the internal ROM or the
external SPI in order to boot the system.

If I understand this correct this is an output that can be used to hold external chips in reset until power is good and CPU starts.

I cannot find any documentation on the RST pin on Omega2 module.
Does anyone know what it do and how can it be used?
