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。# `& p- q3 i* u, ^ 5 Z2 `7 I/ ^' A9 | 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 h& k i4 ]" s 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（427.627 R% h0 Q2 p4 C' P' r; | BogoMIPS，F429跑Linux只有35.847 S/ ^% g. n! w: @3 ^ 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 B1 d' ~& P) c% p* H' S
