各位中文社区用户,
大家好,前一阶段在我们的中文用户微信群中,大家都在积极讨论ARM的新的开发环境DS-MDK。 因为最近用到类似NXP 的i.MX系列的即有Cortex-A处理器,又有Cortex-M处理器的SoC产品的用户越来越多了。大家一方面追求Cortex-A的高速处理能力,又想获得Cortex-M的强大控制能力。往往鱼和熊掌不可得兼。开发起来特别麻烦,比如我在Cortex-A上要跑个Linux,而在Cortex-M上还要跑RTOS。究竟是用DS-5好还是Keil比较好,真是让人难以取舍。
Requirement: Develop a debug layer for new CPU based on DS-5.
1. Basically I want to use jython to develop that, and it could be easily loaded and run on debugger CLT by source command. (e.g. source debug.py).
2. The debugger jython interface enables to…
Dear All,
Please let me intimate the ARM debugger for i.MX53.
Thanks,

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…
