It also uses a new REGION_RODATA region alias for read-only data. Move section .USER_FLASH to REGION_RODATA. This means it lives in RAM under RAM builds. Although this might be surprising, not doing so would make RAM builds useless. Modify the individual board linker scripts to properly set REGION_RODATA and _FLASH_BUILD before calling out to common.inc. Delete common_rom.inc, common_ram.inc, common_header.inc, in favor of common.inc. This should fix RAM builds on all boards. 2011-09-12T21:25:01+00:00 Marti Bolivar mbolivar@leaflabs.com 2011-09-12T20:24:43+00:00 urn:sha1:fc4bd8eb9ea6271ad1e3aa734657808e77ac1e2a - common_header.inc: Declare EXTERN symbols _lm_heap_start and _lm_heap_end. - common_rom.inc: Check for _lm_heap_start and _lm_heap_end. If they are defined, preserve their values. Otherwise, _lm_heap_start is starts after .bss, and _lm_heap_end is the end of SRAM. This allows existing linker scripts to continue using the old heap scheme, but allows for customizability elsewhere. - syscalls.c: Respect the addresses of _lm_heap_start and _lm_heap_end as the boundaries of the heap in _sbrk(). 2011-09-12T20:10:10+00:00 Marti Bolivar mbolivar@leaflabs.com 2011-09-12T20:10:10+00:00 urn:sha1:780381d160730486565eb9a16a191487127d6120 Explain what's going on so unfamiliar readers have more hope. 2011-09-09T19:33:11+00:00 Marti Bolivar mbolivar@leaflabs.com 2011-09-09T03:33:10+00:00 urn:sha1:92ea94ce302f2647154e5b519fa3459a0bf56ede 2011-09-09T19:33:11+00:00 Marti Bolivar mbolivar@leaflabs.com 2011-09-09T03:17:46+00:00 urn:sha1:9eca03d946d7c44210f8b23c838bb99e48aed4ce 2011-09-09T19:33:11+00:00 Marti Bolivar mbolivar@leaflabs.com 2011-09-09T02:45:37+00:00 urn:sha1:3668462312ddb8d1eabb9da1e529825d96224166 2011-09-09T19:33:11+00:00 Marti Bolivar mbolivar@leaflabs.com 2011-09-09T02:12:01+00:00 urn:sha1:e5997185942fd1edb8b74b5ed2cee2a795df92bc Use region aliases in common_ram.inc, common_rom.inc.

Factor this out into a new file common_header.inc, and have the main linker scripts include this file. Apart from eliminating a redundancy, this will make it easier to add new linker scripts in the future. 2011-02-27T20:56:40+00:00 Perry Hung iperry@gmail.com 2011-02-27T20:49:51+00:00 urn:sha1:43d6921658cd29b8022af4424d340a90fbcb9a7f Add common linker scripts for ram and rom.
