rockbox/utils/hwstub/lib, branch 2048sp5 My Rockbox tree hwstub/qeditor: add support for atomic read/writes 2014-11-18T22:30:44+00:00 Marcin Bukat marcin.bukat@gmail.com 2014-11-18T22:27:26+00:00 cd04a5f1aadc8e2ec4e787f5ba4cc8c38a579314 The current code assumed that READ/WRITE would produce atomic read/writes for 8/16/32-bit words, which in turned put assumption on the memcpy function. Since some memcpy implementation do not always guarantee such strong assumption, introduce two new operation READ/WRITE_ATOMIC which provide the necessary tools to do correct read and write to register in a single memory access.

utils/hwstub: completely rework the protocol, drop unused features 2014-02-10T22:14:24+00:00 Amaury Pouly amaury.pouly@gmail.com 2014-02-03T23:10:41+00:00 c17d30f20466861a244c603665c580feb7758abf The protocol has evolved a lot during the 2.x.y lifetime, bringing more features which later got unused. This commit removes all the unused stuff and simplifies everything: - drop the feature mask: everything is mandatory or stalled on error - remove the info request and put all static information in standard USB descriptors which are part of the configuration descriptor (and can be retrieved using the standard GetDescriptor request). - remove the USB interface, we had only one anyway - remove all endpoint descriptors - remove the exit/atexit stuff, it never worked as intended anyway - update the hwstub library and make it able to handle any device - update the tools (mostly renaming and removing of code) Change-Id: I1872bba7f4177fc3891180e8f944aab88f5bde31

hwstub: enhance exit protocol and implement on stmp 2013-07-16T17:29:42+00:00 Amaury Pouly amaury.pouly@gmail.com 2013-07-16T17:29:42+00:00 e5de5e09c1ca6788d155393af0d906a9402ea7bc Rename STOP command to EXIT, introduce ATEXIT, this gives better control over the exit of the stub.

hwstub: major improvement in the stub and the tools 2013-06-13T00:25:15+00:00 Amaury Pouly amaury.pouly@gmail.com 2013-06-13T00:02:53+00:00 c5357940ab0108b4102442d07825c44d5be0d22f Fix the stub in many way to correctly detect the STMP family and act upon that. Drop some unused commands and bump version. Rewrite the tool to allows scripting in lua and load the register description from an XML file using the regtools. Introduce a new tool to load and run code using the hwstub (either binary format or Rockbox additive scramble format). Also switch to an optimise version of the memcpy/move/set functions to correctly handle alignement issue (like writing a full word/half-word when possible for registers which is crucial) Change-Id: Id1d5cfe0b1b47e8b43900d32c5cd6eafae6414f6
