The second set of patches for LTS release 20120406 is now available on SourceForge at http://sourceforge.net/projects/mspgcc/files/Patches/LTS/20120406/
SF 3562063 "delay_cycles wrong when optimization disabled" reported against this version (by me after it was discovered at 43oh.com) has been fixed in 20120911, but does not meet the criteria for an LTS patch: I don't entirely trust the fix to be impact-free; it did not back-port cleanly; and the problem does not occur under normal use with optimization. (The issue is that an extra comparison gets generated within the delay loop.) Below are the patches that are supported. msp430-gcc-4.6.3-20120406-sf3540953 : SF 3540953 fram applications overwrite bsl/jtag passwords This patch is the version that was been in 20120716 and has proved stable. Its effect is to set the lower 32 entries in the interrupt vector table to 0xFFFF when compiling for an MCU with a 64-element interrupt table. This has no effect on any current MCU (fewer than 30 interrupt vector entries are used in current MSP430s), but leaves the BSL and JTAG password values erased on the FR5XX chips which place them inside the interrupt table. There is no facility to set these entries to any other value within the LTS release. The lower entries are overridable in the 20120911 release, but that patch was too invasive to apply. msp430-gcc-4.6.3-20120406-sf3559978 : SF 3559978 broken volatile peephole optimization A bad peephole pattern would result in incorrect code transformations. The pattern has been corrected.
