(Sorry for posting about uboot on the eldk mailing list. I am now posting it on Uboot mailing list)
Hi,
For my Cortex-A5 based ARM Processor (from ADI), I'm trying to compile old uboot (2015.01) release with a new compiler (gcc6). Its giving the following error:
arch/arm/cpu/armv7/sc58x/lowlevel_init.S:24: Error: selected processor does not support `vmsr FPEXC,r0' in ARM mode
portion of lowlevel_init.S /* * Enable VFP unit */ mrc p15, 0, r0, c1, c0, 2 orr r0, r0, #(0xF << 20) mcr p15, 0, r0, c1, c0, 2 mov r0, #0x40000000 vmsr FPEXC, r0
Compiler arguments (for arm-none-linux-gnueabi-gcc): -D__KERNEL__ -D__UBOOT__ -DCONFIG_SYS_TEXT_BASE=0xC2200000 -D__ASSEMBLY__ -g -D__ARM__ -marm -mno-thumb-interwork -mabi=aapcs-linux -mword-relocations -march=armv7-a -mno-unaligned-access -ffunction-sections -fdata-sections -fno-common -ffixed-r9 -msoft-float -pipe
The same compiler arguments when used with old gcc (arm-none-eabi-gcc) version 4.8 compiles this file.
Any ideas what I may be doing wrong or any suggestions on how to get past this?
Regards, Pj
