I've added some debugging output below. For testing purposes I modified the code to ignore the unknown 0xAE return code being hopeful that it would work anyways, which it didn't. The return code 0xA4 which occurs with the next command indicates RSP_ILLEGAL_EMULATOR_MODE, so it would seem there is something wrong with assigning the PDI emulator mode. Knowing the meaning of the 0xAE return code would probably help figure out what is wrong. Could there be an incompatibility with this version of the firmware (7.39 it seems)? I may try downgrading to some older version. If anyone knows what version is a good candidate for me to try, that would be helpful.
Of note is that the avarice is silent about the error occurring with the command following the emulator mode assignment. It wasn't apparent to me what was wrong (if anything) until I was stepping through the application with gdb.
