Compiling u-boot for LS1043ardb Arm 32bit

[niharunadkat]

Hi all,

I am compiling uboot for a 32 bit arm and i am getting errors as shown below

{standard input}: Assembler messages: {standard input}:33: Error: selected processor does not support requested special purpose register -- `mrs r0,cntfrq_el0' {standard input}:63: Error: selected processor does not support requested special purpose register -- `mrs r0,cntpct_el0' {standard input}:95: Error: selected processor does not support requested special purpose register -- `mrs r2,cntfrq_el0' {standard input}:117: Error: selected processor does not support requested special purpose register -- `mrs r3,cntfrq_el0' scripts/Makefile.build:280: recipe for target 'arch/arm/cpu/armv8/generic_timer.o' failed make[1]: *** [arch/arm/cpu/armv8/generic_timer.o] Error 1 Makefile:1223: recipe for target 'arch/arm/cpu/armv8' failed make: *** [arch/arm/cpu/armv8] Error 2.

Can anyone help me with this issue.

Thank you.

You are right. The latest SDK 2.0-1701 supports the LS1043 in AArch32 mode. I have tested this SDK.

Add EULA file in the QorIQ-SDK-V2.0-20160527-yocto/build_ls1043ardb-32b/tmp/work/ls1043ardb_32b-fsl-linux-gnueabi/rcw/git-r0/git folder.

Have a great day,

NXP SDK supports only 64-bit version Linux and u-boot. See documentation for LS1043ARDB board in the SDK 2.0 documentation:

In latest QorIQ-SDK-2.0-1701-IC-Rev0.pdf, Chapter 8.7 describes that LS1043 can run on AArch32 mode.
