Hello, everyone

I'm new to this community.

I'd like to ask many questions and want to help someone.

Now I have some difficulties in understanding aarch64's watchpoint exception handling scheme.

I found I can decide which exception level whachpoint…

the booting of seconday cpu is initiated by the primary core. and some work is completed on the primary cpu and some is completed on the secondary cpu to complete the hotplug operation for cpu_up.

I am trying to find the exact instruction that is executed…

1、Arm compiler 6 下target分为两种：aarch64-arm-none-eabi（对应AArch64执行状态）和armv8a-arm-none-eabi（对应AArch32执行状态），当target设置为aarch64-arm-none-eabi时无法使用内嵌汇编指令QADD、QADD16等，当target设置为armv8a-arm-none-eabi时可以使用内嵌汇编指令QADD、QADD16等，这应该是和两种执行状态各种的指令集相关，但是前面提前的可以编译时在Debug下…

If a char parameter is passed to a routine in Aarch64 is the top of the word undefined? and is the same true for if a char value is returned? I think the answer is yes but it would be good to be certain. This means if the char is used in some arithmetic…

哪个亲知道ARM-V8的AA64与ARM-V7 LPAE的MMU Table差距多少？

ARM DS-5自带的example看起来挺麻烦的，关键是没有run起来，光看代码没有效果！

Hello everyone,

I hope to find some assembly language examples of ARMv8 AArch64 instruction set.

Where can I find them?

Thank you in advance !

I am using ARM DS5 Ultimate Edition (Version 5.18.0)

Target aarch64-arm-none-eabi is being used for compilation.
I am trying to run the .axf on ARMAEMv8-A_MP_0.
While running the .axf I am getting this error:-
ERROR(CMD426): Cannot find symbol to start or…

Hi experts,

The PMU counter value is mentioned as 64 bit in ARMV8 manual.

What is the PMU counter resolution when the processor switches between 64 bit and 32 bit mode

Is it possible to run an baremetal application with fileio on the ARMv8 Foundation model.

If so do you have example linker script?

In open source which is gcc cross toolchian available which can support AARCH32 and AARCH64 based on –mabi flag ?

In gcc documentation, supported values for –mabi are ilp32 and lp64. But when I tried linaro released toolchain crosstool-NG linaro…

Hi,

i'm doing some experiments on Aarch64/Aarch32 using the Foundationv8 simulator.

For starting, i got the linux/bootwrapper/toolchain code from linaro, compiled the software and the linux kernel in 64 bits without any problem.

Then i started modifications…

Hi,

I have a 64bit application running on armv8(foundation model)

My question is

1. Can I link aarch32 library to aarch64 application ?

2. Is there a way to enter aarch32 state when application is running in aarch64 state in Exception level 0 ? I tried…

I would like to develop code for A57 (AARCH64). What toolchain should I use for ARM simulator? can i insert it into DS-5 eclipse enviornment? Is there a eclipse plugin? If not what do I set to build debug in DS-5? what are my options?
