Just a wish.

[John Källén]

Any particular one of the PDK13, PDK14, PDK15, or PDK16 you're interested in?

[kimstik]

Particularly I'm interested in PDK15 and 14.
I'm not sure that PDK16 even exist in reality.

[John Källén]

Commit 038acf4 has an initial implementation of a disassembler and a rewriter to IR. Code quality could improve once provided with processor model-specific details. Here I ask that you consider volunteering some time to collect information about memory address register semantics, and perhaps generating data that could be ingested by Reko when loading the Padauk architecture.

CmdLine-0.11.4-cedeb234d1.zip
decompile.exe --default-to intel-hex --arch padauk ulp_blinker.ihx
Got "Error: Cannot decompile ulp_blinker.ihx."
ulp_blinker.ihx.zip

[John Källén]

Can you tell what instruction set it is? Reko currently supports PDK14 and PDK15, but you'll need to open a separate issue if you want support for PDK13 or PDK16.

[John Källén]

There were some issues that have been fixed. Use commit 603817e or later. Also, be aware that the command line syntax you need to use is

reko.exe decompile --loader intel-hex --arch padauk --arch-option isa=PDK15 ulp_blinker.ihx

The command-line driver's name has been changed from decompile.exe to reko.exe.

If you find any other issue, please report it in a separate, new issue.
