Dadebug assembler modules in rom

Does anyone have DADebug working with assembler modules in ROM?

I have dadebug working with C modules in ROM and softloaded assembler modules but when I put the assembler module, which outputs to dadebug info ok when softloaded, in rom the rom fails to start.

Can anyone confirm that I should be able to get dadebug output from assembler modules in rom.

It turns out that DADebug doesn’t work for assembler modules because Debug_Open and Debug_Close in NdrDebug write a value to dadebug_writec which is in the code area as NdrDebug doesn’t have access to workspace.

In case it helps anyone else I worked around it as follows:

1) Compile a rom without any debugging set with the DaDebug module loaded just after the kernel.
2) With the rom working read SWI DADebug_GetWriteCAddress r0
3) Modify Export.APCS-32.Hdr.Global.NdrDebug in the sources folder by commenting out where dadebug_writec is written to and setting the value of dadebug_writec to the value read in (2).
