Net+Os v5.1 with GHS 3.5 & GNU

What it is… Inter Release that allows you to run Net+Os on 7520 based targets… The BSP has been restructured to make it easier to port. A bootloader has been added. The bootloader provides a way to automatically recover from a bad flash update.

Bootloader Feature… All example applications have been updated to work with the bootloader. When an application is built it creates an image that can both be debugged with the MULTI debugger, and be stored into flash and loaded by the bootloader. An example application, ROMZIP, has been added that demonstrates how to create the equivalent of the ROMZIP applications from Net+Os v4.0 and v5.0. Accordingly Support for ROMZIP builds have been removed from the example applications.

The file bspconf.h is used to control BSP configuration settings. The #define CLOCK_SOURCE directive in bspconf.h determines the clock source to be used. It is the address input to the SYSCLK signal multiplexer. The SYSCLK has two possible sources: –One from the TTL clock input applied to the XTAL1 pin –The other from the Crystal Oscillator and Phase Lock Loop circuit. –When CLOCK_SOURCE is 0, SYSCLK uses the XTAL1 its source. –When CLOCK_SOURCE is 1, SYSCLK uses the Crystal Ocsillator and PLL as its source.
