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

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
