I’ve got a vintage project, originally written for Net+O/S 4 using the Greenhills compiler, which I’d like to install on a few more systems. The PC running Greenhills has long since been scrapped (now mostly using ESP with Net+O/S 7.4) and the requirement doesn’t justify resuscitating the old Greenhills stuff, or porting to Net+O/S 7. (The BSP was customised a bit, including a non-standard flash part).  
We used to set boards up via the JTAG port, with some Greenhills utilities.  
I’ve got all the downloadable files, Raven Debugger and so on - has anyone any tips on how to proceed?
