跨界单片机NXP i.mx-rt1050 uclinux源码哪儿可以下载？
RT,有坛友知道么？不知道大家对1050跑linux感不感兴趣？不是说Linux主线已经支持不带MMU的处理器了吗？干嘛还搞ucLinux，，直接上Linux吧{:lol:} 2楼正解。
另外，要跑LINUX，一大把片子选，为何要选贵族芯片飞思卡尔？ https://emcraft.com/products/819#overview
给你个链接看看吧，这个就是nxp里直接跳转的 uclinux shuiluo2 发表于 2018-1-3 09:57

600mhz主频，内置PMU，批量价格3美刀。
mcu和mpu跨界产品你还能找到第二款？ mubei 发表于 2018-1-3 10:00

谢谢，没有mmu，只能跑uclinux。只有演示imag, bsp源码包需要付费. 在官方EVK板上跑了个demo镜像:

刚看了一下，下载BSP确实需要钱。STM32的是免费的，只需要注册。
等一段时间这个芯片的支持应该会加到linux kernel里，需要耐心。 rt1050为啥某宝还卖50多?3美金什么时候有? ayuanshop 发表于 2018-1-4 11:14

我查了下，是野火搞的，还没正式发售 外观风格看上去有点像他们的东西。 无论是速度还是尺寸 这个芯片应该是支持DDR的 又一块鸡肋
