前段时间ST推出了Value Line的STM32F750和H750两个系列，看了一下选型表，F750有LQFP144封装，正好适合我的STM32 linux板子。 y; R( P5 Q5 p 于是，双十一买了几片。同时，我对我的linux板做了小幅改版：将SPI Flash容量扩大到32MB并连接到F750的QSPI BANK1，添加了CAN收发器和接口，增加了两个I2C外设（温湿度传感器和气压传感器）。板子做回来后先焊了一片，调试过程还算比较顺利，现在u-boot和Linux都工作起来了，下面是系统启动log，F750速度还是相当快的（427.62% T. y2 A9 v! z& t$ i BogoMIPS，F429跑Linux只有35.84 BogoMIPS），QSPI的加载速度也很给力。下一步我准备多测试几种STM32外设的Linux driver，emcraft现在的SDK比两三年前多了不少外设驱动，可以都试试看。. a6 C" W8 y3 T4 v' ^* X / B7 ^$ s3 y; V d.
