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。9 ^0 ]1 b: w! b* J9 Y 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QSPI0 P$ m9 V' @$ w- J9 A: J4 V 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 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。; {& _0 @2 q1 b! k 1 T; L2 {/ T; R q s) C: i
