芯片哪搞啊，万能宝木有啊

晕哥在小黄鱼有卖，买了两片还送了我一块F1C600的板子:D

mango 说：

意思是他这个DLL直接把A7架构限制住了？

对，应该是这样的，发现是A7内核，就中断调试。
但是不知道如何破解这个限制。

焊接完成，烧录系统，正常运行

邮票孔版本，明天上班就去打板板

你们这个核心板好像和启明的有点像额，出来了吗，什么配置什么价，准备搞几块来吃灰:)

哦，比他们的小了一大圈。价格应该保持极高性价比，放心吧。

请问楼主，板子大概啥时候能买到？

春节前出demo板，春节后量产。

这板开源还是卖钱？有订购链接么？

内置的SPI Flash在单线模式下频率可达100 MHz，2线和4线模式下最高频率为80 MHz，因此确实会严重影响执行效率。
解决方法是搬到SRAM运行，在SRAM上执行就是零等待时间了。NUC505可以将SRAM以bank为单位（共4个bank，一个bank对应32 KB）映射到代码段空间（0x0-0x1FFFFFFF），所以映射后不会有性能问题。NXP的LPC43x0也是一样的解决方法。
