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 2009-08-28 00:07:35 +08:00			`INCLUDE ../common/ldscript.common`

fix loader memory mapping 2009-06-29 21:26:35 +08:00			`ENTRY(Vector)`
Initial commit for the firmware. Used the 20090306_ela version as baseline. It is identical to the popular 20081211, with the doob addition (20090301), a linux client, and two additional commands for LF analysis. Let me know if you find issues here! 2009-04-09 14:43:20 +08:00			`SECTIONS`

Only re-compile version.c as often as necessary Make bootrom version information pointer a proper symbol (with hacky ld strangeness workaround) 2009-08-29 14:14:28 +08:00			`.fpgaimage : {`
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 2009-08-28 07:29:49 +08:00			`*(fpga_bit.data)`

Fix data segement. You may now use stuff like int foo = 1; in global context (as opposed to both int foo = 0; which is bss and const int foo = 1; which is rodata) without having the sky come crashing down 2009-09-08 23:40:22 +08:00			`*(.version_information)`

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 2009-09-01 22:44:38 +08:00
