Re: [Sdcc-user] On-Target Hardware Debugger for the 8051

[Maarten B. <sou...@ds...>]

Hello Randy,

On first impression I think the CCDEBUGGER is only supported by the 
IAR-tools for In-System-Debugging. For Flash-downloading only you 
can also use the TI Flash Programmer software.

If you are willing to invest the time however you can implement your 
own debugger as the debug protocol is fully described in the user 
manual.

Also note that SDCC is not binary compatible with IAR and thus it 
will require intermediate assembly to call functions in the IAR BLE 
library. Maybe you can ask TI for an SDCC library of the BLE stack 
or even the sources.

Greetings,
Maarten Brock
