他總結根本原因：
NXP大面積使用BGA，這對于學生和小公司而言，BGA的焊接成本高、維修麻煩，學生和技術員很難快速自學，學生不用，畢業(yè)后也會“引導”老板不用。
此外，BGA也導致工程師在項目選型階段就直接放棄NXP，除非沒得選擇，否則沒有人愿意給自己的調試和生產添麻煩。
人人都知道，NXP的MCU，在性能上和配置上不比ST差，但是普及化推廣上，嚴重缺失中文資料、開發(fā)套件、QFP芯片封裝、技術支持等等。
其實，NXP的RT系列在性能上完爆ST的H7系列，而且價格也不貴，但是，國內沒多少RT的開發(fā)板，而H7的一大堆，這就足以說明這2款在國內的狀態(tài)。
有些網友對樓主的觀點表示同意，有些網友回復表示：
21ic藍V作者吶咯密密認為：“的問題就是資料的開源度和技術支持，學ST的時候我也不會焊芯片，但是買一個正點原子的開發(fā)板跟著視頻就學會了。買NXP只能吃灰，遇到問題都不知道怎么解決，不過NXP的芯片是真心好！
fcccc表示，NXP的開發(fā)板也不少，主要還是大部分同規(guī)格產品價格都比st貴的多。同樣問題還有瑞薩，也是價格相對較高。再一個就是瑞薩仿真器太貴，而那些便宜的乞丐版仿真器速度慢的要死。不知道瑞薩靠賣仿真器能掙多少錢，干嘛不把E1開放。ST成功的原因還有一個就是STlink超級便宜，當然DAP出來之前還有國內xx的Jlink也功不可沒，幾十塊錢百來塊錢學生買來學習都可負擔得起。
