Your LEON, fitted into your FPGA, will usually boot from its internal bootstrap
code called PMON bprom (see file pmon/bprom.c). The size of this bootstrap is
less than 1 KByte. This program does at power-up the following things:
- Initialization of registers PSR and WIM
- Initialization of I & D Caches
- Initialization of UARTs 1 & 2
- Initialiazation of Timer 1
- Configure RAM memory access (especially MEMORY Configuration Register 2)
o RAM bus width auto-detection
o Number of RAM banks auto-detection
o Determine the size of each RAM bank
- Initialization of the Stack pointer
- Display result of the AM auto-configuration on UART1
(write a string: e.g. LEON-1: 1*4096K 32-bit memory
- Wait for your downloaded S-Record program

To download your application program into LEON's RAM, use the "send file"
feature of terminals such as HyperTerminal or TeraTerm.
