hi :
I know , we can flush L1 I/D cache items to PoU with kernel interface(flush_cache_*).
however, I can not find any clue about flushing L2 cache to DRAM(if without L3).
and I saw some points that L2 flushing was not needed.
for ARMv8, how can…

Does anyone know where I can find the toolchain for developing apps on an A57 (Raspberry Pi 3) in Assembly Language? I am looking in particular for a Windows toolchain that will allow me to cross compile, but I'll take anything at this moment since all…
Hi,
I am using ARM cortex A-57 processor and I build image with my own startup code and ld script. The image is loaded with u-boot. When I tried booting the image, it is aborting with following message:
## Booting kernel from Legacy Image at 48080000…
Hi ,
I am running aarch32 app in ARMv8a( cortex-a57 ) device. The performance reports ( using gettimeofday() utility ), showing large spikes on random calls. But the same app on ARMv7a( cortex-a15 ) device is quite stable.
Will the aarch32 library…
hi, experts:
在看ARMv7/v8 ARM手册的时候,总是不太明白CoreSight / ETM / CTI等等,它们之间的关系。
以Cortex-A57 MPCore TRM的Figure 2-1为例:
它展示了CA57's block diagram
1. 如果仅仅使用JTAG tool,通过HW/SW breakpoint进行debug
只需要:Debug-->APB --> Debug and CTI --> Debug path…
Hello,
I want to experiment with a storage solution ARM based. Is there any provider actually selling dev kits or consumer boards based on ARM Cortex-A53 or ARM Cortex-A57?
Obviously the main requirement for purchase is the availability of SATA3 ports for…
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?
近期大陆手机产业内盛传手机晶片厂联发科面临高通、英特尔的激烈竞争已经疯了!将再掀起“核战”推出10核心手机晶片Hileo X20。据瞭解,目前被看衰第2季成长不到两成的联发科,确实将推出10核心晶片,最快在今年第3季出货为下半年旺季新添战斗力,让终端客户可以赶在年底 前上市销售新一代高阶机种。
不过,联发科这次不是为了打核战,而是着眼于推出独步全球的创新3架构公板设计,引领手机和汽车一样进入Turbo高效节能时代,企图抢攻高通的高阶手机晶片市场…
[导读] ARMv8是一个真正意义上的64位,同时这个64位的架构当中加入了或者说提供了32位的支持。Cortex-A57是ARM最先进、性能最高的应用处理器,而Cortex-A53不仅是功耗效率最高的ARM应用处理器,也是全球最小的64位处理器。

我最近有机会去回忆过去五年中的移动计算革命。 我之所以专门用“移动计算”这个词,主要是因为我们在移动电话上能处理的任务已经和过去几年中我们只能在笔记本电脑或者台式机上处理的不相上下了。因为笔记本和台式机有来自墙角电源的不间断供电,所以他们需要风扇来冷却, 这也是他们的架构设计的基础。而今天的移动设备一次充电就能和他们一样工作一天…
