| 271 fc-tmsync aur and aur-all addition | |
| 272 ================================== | |
| 273 | |
| 274 New addition as of fc-host-tools-r16: our aur command which natively resides in | |
| 275 fc-tmsh (audio mode full access read operation via ETM) has also been | |
| 276 implemented in fc-tmsync for scripted usage. Furthermore, we also implemented | |
| 277 an aur-all command that issues the same sequence of aur operations as the | |
| 278 firmware's built-in audio_mode_save() and emits the output on stdout in the same | |
| 279 format as tiaud-decomp. The end effect is that fc-tmsync aur-all is a much | |
| 280 shorter and more direct way of obtaining exactly the same result as would | |
| 281 previously be obtained by saving the current audio mode config with aus, reading | |
| 282 out the resulting binary file with fc-fsio and decoding it with tiaud-decomp. | |
| 283 | |
| 284 The implementation of aur-all and the more elementary aur 12 command in | |
| 285 fc-tmsync works only with firmware versions that have L1_NEW_AEC enabled - | |
| 286 therefore, these commands work with FC Tourmaline but not Magnetite. | |
| 287 | |
| 288 Furthermore, our aur command in both fc-tmsh and fc-tmsync and the new fc-tmsync | |
| 289 aur-all command also work against Pirelli's firmware - this alien fw implements | |
| 290 ETM aur operation exactly the same as standard TCS211, and it has L1_NEW_AEC | |
| 291 enabled, such that aur 12 returns the 24 byte long L1_NEW_AEC version of | |
| 292 T_AUDIO_AEC_CFG structure. The combination of this functionality in Pirelli's | |
| 293 fw and our fc-tmsync addition makes it possible to read out Pirelli's highly | |
| 294 tuned audio configurations in a very convenient manner, much more convenient | |
| 295 than reading ABB registers with abbr and reading DSP API words with r16. |
