Fix FPGA load code for the generic case where a new style bitstream is not DWORD aligned
Completely switch to byte-wise load, shouldn't make much of a difference since this is not timing-critical
New bootrom
+ Add common area at end of RAM to communicate between main os and bootrom
+ Lower stack end to make room for common area
+ Implement CMD_DEVICE_INFO in both OS and bootrom to give information about the current state and supported features
+ Allow hands-free firmware update: When CMD_START_FLASH is received over USB in OS mode, the device will reset and enter the bootrom
Pressing the button in hands-free update mode takes precedence: releasing the button will immediately abort firmware update and
perform a reset. Do not press the button.
+ Require each flash sequence to be preceded by a CMD_START_FLASH to set up the boundaries for the following flash sequence
Not compatible with linux flasher before SVN revision 200
Currently no compatible flasher for Windows. WINDOWS USERS: DO NOT UPDATE YOUR BOOTROM YET
+ Protect bootrom flash area unless magic unlock sequence is given in CMD_START_FLASH
New flash tool, needs to be ported to Windows.
+ [f]ast is gone, current mode will be autodetected
+ uses hands-free firmware update if supported by the bootrom (to be committed)
+ uses new bootrom safety features against accidental misflashes (to be committed)
+ supports S19 files with base address 0x0 or base address 0x100000
+ supports old bootroms which expect 0x0 and new bootroms which expect 0x100000 (to be committed)
+ new argument style: first argument is comma-separated (no spaces!) list of partition names, remaining arguments are file names
os and fpga may be abbreviated, bootrom must be given in full
Examples: ./flasher os ../armsrc/obj/osimage.s19
./flasher bootrom,o,f ../bootrom/obj/bootrom.s19 ../armsrc/obj/osimage.s19 ../armsrc/obj/fpgaimage.s19
Implement version information storage and retrieval for the bootrom and the osimage.
Use perl to create the version information (thereby re-creating the perl dependency and adding an svn dependency) but fall back in case of missing perl or svn
Add Makefile for fpga directory (Windows codepath is untested, in any case, go.bat is still there)
Retire rbt2c.pl, instead use objcopy to directly convert the .bit file into an .o that can be linked with the flash image
Rename armsrc/fpga.c to armsrc/fpgaloader.c (since there is now a new fpga.o, created from fpga.bit)
Remove fpgaimg.c from subversion, add fpga.bit
Instead of creating fpgaimage.elf and osimage.elf separately, now create a joined fullimage.elf
first (obsoleting ldscript-full), then extract only the fpga and os sections with objcopy
(This creates unspecific warnings about an empty segment, need to investigate)
Implement a rudimentary .bit parser in the firmware, use that to locate the bitstream in the new
fpgaimage (which is just a plain copy of the fpga.bit file) and send it to the FPGA
The code will check the format that's in flash and fall back to the legacy format
Add a common linker script with the memory map for the complete project
Use the correct physical addresses in the memory map, and instead translate the addresses during postprocessing with objcopy
Merge linker scripts in bootrom to have a single linker script for the bootloader proper (previously known as bootrom-merged.s19)
Remove the now unnecessary files (merge-srec.pl, ldscript-ram-jtag)
Note that this drops the dependency on perl for bootrom build, so end-users who don't touch the FPGA bitstream will not need perl anymore
Move most rules to Makefile.common
Add automatic dependency generation
Compile ISO14443 files in ARM mode, as was the case with the Linux Makefile before
Consolidate Linux/Windows Makefiles into one, see http://www.proxmark.org/forum/topic/312/consolidating-makefile/
+ Needs GNU make for Windows, a new release of the Windows development environment will follow
+ Is based on the Windows Makefile, so will build everything in Thumb mode, doesn't have flash commands (yet)
