[U-Boot] [PATCH 0/2] calimain: Generate random MAC address for factory testing
by Christian Riesch 08 Jan '13

08 Jan '13

Hi, This patchset allows the calimain board to use a random MAC address if no MAC address has been set yet. We use this feature for tests during production of our boards. Later, official MAC addresses are assigned to the boards. To seed the random number generator I use the content of the uninitialized SRAM of the AM1808 SoC.
