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
