Hello! I have maybe strange problem, my knowledge is not enough to solve it, so I`m try to find help here. I have a board with ARM SoC Hi3531. Brief datasheet - http://www.hkvstar.com/pdf/Hi3531.pdf Specs of processor is: ARM Cortex A9 dual cores â Up to 930 MHz â 32 KB I-cache and 32 KB D-cache â 256 KB L2 cache I have an SDK for it. SDK contains linux kernel 3.0.8 with some editions for support this device (march-godnet dir in /arch/arm). Toolchain is arm-hisiv200-linux-gcc (Hisilicon_v200(gcc4.4-290+glibc-2.11+eabi+nptl)) 4.4.1 There are some precompiled modules for this SoC. Note said that: Hi3531 support hardware floating-point. And all libs in default file system are compiled to hardware floating-point. So it's strongly recommen$ CFLAGS += -march=armv7-a -mcpu=cortex-a9 âmfloat-abi=softfp -mfpu=vfpv3-d16 CXXFlAGS +=-march=armv7-a -mcpu=cortex-a9 âmfloat-abi=softfp -mfpu=vfpv3-d16 So, as I understand my ARM is armv7-a, cortex-a9, softfp, vfpv3-d16 On the board there is installed U-boot to SPI slash memory chip. I can connect to board via serial port and get access to U-boot. So, I can use my kernel via usb or TFTP and edit kernel boot params. If I compile kernel with toolchain from SDK, everything is good, kernel loads. I try to build my own toolchain for this SoC, with last gcc, binutils and glibc via crosstool-NG 1.9.0 I have a number of different configs for crosstool-NG, it builds toolchain with no errors, but when I compile kernel (it builds ok), after booting it via U-boot nothing happens, no errors just a string Uncopressed kernel ok, booting... (something like this words) After it usually there is some boot log, but it seems something goes wrong. I think my mistake is somewhere in configuring Target options menu (ct-ng menuconfig) I choose: Target Architecture - arm Suffix to the arch-part - nothing Build a multilib toolchain - NO Use the MMU - Yes (SoC supports it) Endianness: - Little endian Bitness: - 32-bit Architecture level Emit assembly for CPU - cortex-a9 Tune for CPU - nothing Use specific FPU vfpv3-d16 Floating point: softfp Target CFLAGS - nothing Target LDFLAGS - nothing Default instruction set mode - arm Use Thumb-interworking - no Use EABI - YES I use headers from my kernel tree. gcc - 4.8.1 As I understand settings of binutls, glibc, and others don`t affects step of kernel building and booting, so I left them defaults. So, I think I need to config Target options right to build and boot kernel. I`m asking for advice or way to solve this.
