There also may be a small time penalty in having the kernel search for the phy. But this would need to be quantified ... Jonathan Cormier

10:46 AM Software Development: RE: MDK_2012-08-10 default configuration

I believe the phy address was set in an earlier version of the kernel and it was carried forward. There is also the ... Jonathan Cormier

09:52 AM Software Development: RE: MDK_2012-08-10 default configuration

Thanks Mike for answer.
I did not look at section 2.2 of TLK100PHP datasheet. It is my fault.
I read section "3... François Tremblay

Mike,
My reply is out of date but it is about that topic: PHY address configuration.
You said that PHY address ... François Tremblay

03:59 PM Software Development: RE: Write to SharedMem from DSP and read it from ARM

Pretty sure you have to flush the DSP cache after changing values. Jonathan Cormier

03:48 PM Software Development: RE: Write to SharedMem from DSP and read it from ARM

Hi,
I am trying to get the shared memory working as well (by writing from DSP side and reading back from ARM side)... Frank C

Thanks Jonathan, that's exactly what I was after. Mostafa Afgani

11:41 AM Software Development: RE: Alter Ethernet MAC

You might also try this technique, though I am not sure if the current version of the 3.2 kernel has this command lin... Michael Williamson

11:26 AM Software Development: RE: Alter Ethernet MAC

Mostafa,
We store the mac address on a eeprom on the SoM. The settings stored on this can be accessed using the f... Jonathan Cormier

11:01 AM Software Development: Alter Ethernet MAC

Hi, is it possible to alter the 'burned-in' MAC address of an L138F? I know that I can change it using 'ifconfig eth0... Mostafa Afgani
