Hi All, I had an issue with the cross toolchain. When i compile the kernel with version 4.2.0 CodeSourcery Sourcery i can boot the kernel without any issues. But when i compiled with arm-linux- tool chain, i am getting an alignment exception. Did any one faced this? Following are the boot prints when compiled with arm-linux- toolchain: Uncompressing Linux............................................................................................... done, booting the kernel. <5>Linux version 2.6.22-omap1-omap2evm-ms1 (arun@localhost) (gcc version 3.4.4) #28 Thu Jan 31 21:50:54 IST 2008 CPU: ARMv6-compatible processor [4107b366] revision 6 (ARMv6TEJ), cr=00c5387f Machine: OMAP2530 evm2530 board Memory policy: ECC disabled, Data cache writeback <7>On node 0 totalpages: 8192 <7> DMA zone: 64 pages used for memmap <7> DMA zone: 0 pages reserved <7> DMA zone: 8128 pages, LIFO batch:0 <7> Normal zone: 0 pages used for memmap <6>OMAP24302 <6>SRAM: Mapped pa 0x40200000 to va 0xd0000000 size: 0x100000 CPU0: D VIPT write-back cache CPU0: I cache: 32768 bytes, associativity 4, 32 byte lines, 256 sets CPU0: D cache: 32768 bytes, associativity 4, 32 byte lines, 256 sets Built 1 zonelists.
