niosecos contains a generic end user bootloader. This bootloader
is a end-user oriented bootloader that solves a number of important problems for
Altera Nios applications, e.g. using Cyclone III "Remote Systems Upgrade" feature to allow the FPGA and
application FPGA bit file to differ. Although this bootloader exploits eCos, the application does
not have to be an eCos application.
A version nios2ecos51.exe of eCos for Nios adapted to be independant of Quartus
and eCos version and drivers for OpenCores Ethermac. Works with eth_ocm_80_2.zip.
Eclipse CDT has excellent GDB support. However, there may be potential difficulties
when attempting to debug embedded applications.
Zylin has made some modifications in Eclipse CDT for Windows/Linux+, a plug-in to
improve support for GDB-embedded debugging in CDT for eCos applications.
Zylin offers a small footprint CPU, complete with a GCC toolchain. The ZPU offers codesize, which is 80% of that of
ARM7 Thumb, and takes up even less space than small 8-bit controllers.
The ZPU is now open source. See ZPU mailing list for more details.
