RE: ARM Error Undefined FPTR Name

You have to tell it to execute the ARM code with the ARMSYS and ARMSAT instructions. Also, ARM code must be word-aligned (word=32 bits in this context), therefore you can't simply embed it, it needs to be copied in memory to an aligned position, then executed. In other words you need a "launcher" like the one discussed here. You could also install the ARM Toolbox from hpcalc.org and create a string, also as explained on the same old post. The Toolbox will align and launch the code for you, but the small launcher discussed there will do the job well with a lot less overhead for small programs. |
