前段時(shí)間ST推出了Value Line的STM32F750和H750兩個(gè)系列，看了一下選型表，F(xiàn)750有LQFP144封裝，正好適合我的STM32 linux板子。
于是，雙十一買了幾片。同時(shí)，我對(duì)我的linux板做了小幅改版：將SPI Flash容量擴(kuò)大到32MB并連接到F750的QSPI BANK1，添加了CAN收發(fā)器和接口，增加了兩個(gè)I2C外設(shè)（溫濕度傳感器和氣壓傳感器）。板子做回來(lái)后先焊了一片，調(diào)試過(guò)程還算比較順利，現(xiàn)在u-boot和Linux都工作起來(lái)了，下面是系統(tǒng)啟動(dòng)log，F(xiàn)750速度還是相當(dāng)快的（427.62 BogoMIPS，F(xiàn)429跑Linux只有35.84 BogoMIPS），QSPI的加載速度也很給力。下一步我準(zhǔn)備多測(cè)試幾種STM32外設(shè)的Linux driver，emcraft現(xiàn)在的SDK比兩三年前多了不少外設(shè)驅(qū)動(dòng)，可以都試試看。
