* hwstub/jz4760b: add lua code to probe for ei/di and ext instructionsAmaury Pouly2017-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add lua code to check whether ei/di and ext instructions are supported. This is unclear since xburst is somewhere between mips32r1 and mips32r2. Details results are below, but in summary: they don't work (ei has no effect, di/ext cause illegal instruction exceptions) > ./hwstub_shell -q -b -e 'require("jz/misc"); JZ.misc.enable_sram()' \ -f lua/xburst.lua -e "XBURST.test_ext_inst(0xb32d0000)" [...] Selecting soc jz4760b.

* hwstub: add tool to dump memory regions (such as ROM, RAM, or peripherals)Amaury Pouly2017-01-24

* hwstub: add various jz stuff and xburst testsAmaury Pouly2017-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The JZ misc allows to enable and test SRAM. The XBurst code uses the coprocessor interface to analyse the cpu. It also provides a test platform for various features like EBASE and exceptions. I was able to test and confirm that on jz4760b (thus xburst), EBASE works (but top 2 bits are not controllable and always 01). The processor claims to support vector interrupts but this is untested. The values in ConfigX are not to be trusted blindly, clearly some are wrong. I tried to use the JZ4780 Config7 "ebase gate" to change bit 30 of EBASE but it does not work, which suggests that JZ480 uses a newer version of XBurst. Detailled log below: > ./hwstub_shell -q -f lua/xburst.lua -e "XBURST.init()" [...] XBurst: PRId: 0x2ed0024f CPU: JZ4760(B) Config: 0x80000483 Architecture Type: MIPS32 Architecture Level: Release 2 (or more) MMU Type: Standard TLB Config1: 0x3e63318a MMU Size: 32 ICache Sets per way: 128 Ways: 4 Line size: 32 DCache Sets per way: 128 Ways: 4 Line size: 32 FPU: no Config2: 0x80000000 Config3: 0x20 Vectored interrupt: yes Config7: 0x0 > ./hwstub_shell -q -e 'require("jz/misc"); JZ.misc.enable_sram()' \ -f lua/xburst.lua -e "XBURST.test_ebase(0x80000000);XBURST.test_ebase(0xb32d0000) [...] Testing EBASE...

* hwstub: various cleanupsAmaury Pouly2016-12-12
| | | | | | | | | | | | | | | - hwstub load now properly stops reading the log when the device returns a 0 size buffer instead of STALLing - add debug output option to hwstub_load - correctly report transfered size on write error - add some debug error message in usb code so that some errors can be diagnosed more easily - add a batch mode to hwstub_shell to disable the interactive shell - increase usb control timeout to 1sec, 100ms was really tight - cap usb buffer size to ~4000 bytes because libusb has a hardwired limit of 4096 bytes for control transfers Change-Id: Id3200ab99ce70a7a3b09ce7faeaafa4a0fac64c7

* hwstub: port hwstub_shell to the new libraryAmaury Pouly2016-04-08
| | | | | | | | | | | | | | | Also use this opportunity to cleanup support for multiple devices: the shell now supports dynamic changes in the device and will call init() everytime a new device is selected, to prepare a new environment. The shell now honors register width on register read/write. The shell also provides access to variants as follows by creating a subtable under the register using the variant type in UPPER case and having the same layout as a register. For example if register HW.GPIO.DIR has variants "set" and "clr", those can be used like this: HW.GPIO.DIR.SET.write(0xff) HW.GPIO.DIR.CLR.write(0xff00) Change-Id: I943947fa98bce875de0cba4338e8b7196a4c1165

* hwstub: rewrite and expand libraryAmaury Pouly2016-04-08
| | | | | | | | | | | | | Rewrite the hwstub library in C++, with a clean and modular design. The library was designed from the ground up to be aware of multithreading issues and to handle memory allocation nicely with shared pointers. Compared to the original library, it brings the following major features: - support for JZ boot devices, it is very easy to add support for others - support for network transparent operations (through sockets): both tcp and unix domains are support Change-Id: I75899cb9c7aa938c17ede2bb3f468e7a55d625b4

* hwstub: Add ajt213x lua interface for DSP blockMarcin Bukat2015-11-17
| | | | | | | | | | | | | | | | | | | | | | With this you can upload and run code on DSP core in atj213x. The files can be produced using as2181. You can download this assembler from https://github.com/wodz/as2181 You should use extended mode (-x switch) since DSP core in atj is non standard and uses 24bit operands. PX register has different meaning as well and is used as MSB when loading other registers with immediates (immediate field is 16bit in instruction so to set register to 24bit value you need to store MSB in PX prior to this). MAC MR is 56bit accordingly. HIP interface seems to be mapped at standard addresses (except that regular 218x doesn't have HIP). Have a fun! Change-Id: I9a80ca0dd3718ba8435ae8579bfffa66e067e022

* hwstub/qeditor: add support for atomic read/writesMarcin Bukat2014-11-18
| | | | | | | | | | 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 featuresAmaury Pouly2014-02-10
| | | | | | | | | | | | | | | | | 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
