We have seen countless similar problems in the past, which is why we recommend using the reference toolchain, which can be built by running: make crossgcc in the coreboot source tree. On subsequent make commands, the build system will autodetect a successfully built reference toolchain and use that instead of the regular toolchain in the system. Let us know if you encounter any trouble //Peter

Hello Coreboot, I compiled coreboot with GCC 4.9.1 for x86 system, and found a misalignment issue. : Here is the abnormal segment of ramstage.map: 0001d1d0 T _bs_init_begin 0001d1e0 t mrc_cache_update 0001d200 t pch_log 0001d220 t finalize 0001d248 t spi_init_bscb 0001d25c t cbmem_bscb 0001d280 t disable_rom_cache_bscb 0001d2a8 T _bs_init_end Issue 1 : the address of "mrc_cache_update" should be 0001d1d0, but it is shifted to 0001d1e0. Issue 2 : the size of "mrc_cache_update" is 20 bytes, so the start adress of "pch_log" should be 0001d1f4, but it is shifted to 0001d200. Does there any compiler options need to be added for GCC 4.9.1? Thank you, Ryan

Hello Greg, I think I got it. When you say that Intel "retires some part number", you probably mean that Intel has stopped to talk about some architectures (or cpu families) in its official documentation. And "working entry" should mean that those cpu-families are still valid, at least conceptually, today. Furthermore, today's "part numbers"/architectures/cpu-families on Intel manuals are them of the QUARK family. Finally, as for the book you suggested (Computer organization: hardware/software by Gorsline), the point is simply the fact that it talks about those "part numbers"/architectures/cpu-families that are not anymore on official Intel's documentation. Cheers

Hello! I'll echo what you also said Aaron with this one on the X86 family as well: http://www.amazon.com/Computer-organization-Hardware-software-Gorsline/dp/0… That book happens to be extremely important to almost any programmer. It contains several sadly retired part numbers in the book, and of course the members of the original series of system members. It largely talks about the actual beginning entries, the 8086 itself, and others. People here would find it useful because it still describes useful ideas. Even Intel is realizing that the retired the X86 working entries in the series too early, that's why the QUARK family is out now. ----- Gregg C Levine gregg.drwho8(a)gmail.com "This signature fought the Time Wars, time and again."
