Programming the OCM in Full-Custom Configuration
Genesis recommends using Keil compiler (
http://www.keil.com/
) to compile the firmware source
code into a hex file. This hex file is then downloaded into the external ROM using commercially
available ROM programmers.
4.15.3 In-System-Programming (ISP) of FLASH ROM Devices
gm5115/25 has hardware to program FLASH ROM devices. In particular, the
GPIO11/ROM_WEn pin can be connected to the write enable of the FLASH ROM. Firmware is
then used to perform the writes using the gm5115/25 host registers.
4.15.4 UART Interface
The gm5115/25 OCM has an integrated Universal Asynchronous Remote Terminal (UART) port
that can be used as a factory debug port. In particular, the UART can be used to 1) read / write
chip registers (see section 4.17 below), 2) read / write to NVRAM (see section 4.15.1 above), and
3) read / write to FLASH ROM (see section 4.15.3 above).
