This custom RAMCode package includes the following files: - AT91SAM9G20-EK_DataFlash.jflash (J-Flash project for DataFlash) - RAMCodeV2_AT91SAM9G20-EK_DataFlashAT45DBxxxD_LE.mot (Custom RAMCode, compiled for little endian (LE)) - Readme.txt (This readme) - Test_LEDBlinky.bin (Sample application which boots from data flash and toggles two LEDs) ************************************************************************************************************* This RAMCode is designed to be used and has been tested on an Atmel AT91SAM9G20-EK Rev. B, using a AT45DB642D, but it should be compatible to all AT45DBxxxD devices ************************************************************************************************************* Requirements to use this RAMCode: - AT91SAM9G20-EK Rev B. compatible hardware - DataFlash has to be connected to SPI0 - nCS of DataFlash has to be connected to SPI0_nCS1 (PC11) - The J-Flash project assumes that an 18.43 MHz main oscillator is used. Otherwise you have to change the CPU init sequence
