Logic unit: Configuration files Purpose: Added AT572D940HF-EB to Makefile and mach-types, added config file Author: Antnoio R. Costa <antonio.costa <at> atmel.com> Date : 11 Jun 2008
Status: - USB,MACB,MCI,DBGU,USARTS working - Introduced interrput handling on reset to work around a bug on SDRAM controller - Introduced a function to compute system frequency at run-time - Flashes initialised but not recognised - Environment is built-in and temporarly stored in SDRAM
