ISLMON was the first attempt at writing an ISL38xx firmware from scratch.

It compiles with the GNU ARM toolchain.

This is now superseded by the [[FreeMAC]] firmware.


It implements the full [[documentation:UARTPCI protocol]] and the following commands are available :

(optional arguments in brackets)

   * **mr address [length]** : reads memory or hardware registers
   * **mw address value [length]** : writes memory or hardware registers
   * **pc [jump]** : show or set the program counter (was useful to understand the TCM and   memory alias system)
   * **cpsr [value]** : show or set the CPSR
   * **dmar address length** : makes a PCI DMA transfer from PCI to ARM (to address 0x00020000), and prints the result
   * **dmaw address value** : makes a 32-bit PCI DMA transfer from ARM to PCI. Does not work for now.
   * **cpuid** : print the ARM CPU identifier
   * **rom** : jumps to the ROM, this is the same as issuing "pc 0xe0000000"
   * **binary** : switch to binary protocol ; only mr and mw commands are implemented. Used to map hardware registers in the ARM simulator. You leave binary protocol by sending a carriage return.

It will also turn on your device's LED once it has initialized ;-)
