1642 ES2.0更换Flash型号需要哪些操作？

你好，

器件支持并测试过以下型号flash。如果想换为其他型号flash，建议使用QE位(四线模式)出厂即enable的型号，

同时如果是来自其他供应商的flash型号，有两点要求：

• The SFDP response by the SFLASH variant
• If the Quad Enable bit is set in the SFLASH. This is required for the “Boot and test” step to work. That why our recommendation is to select a flash variant that has this bit set from the vendor itself.

本地团队测试过W25Q032FVSIG在手动把QE设置为1后，即可被1642支持。GigaDevice GD25B64C可直接使用。

The AWR1243/XWR1443 devices have only been tested with Spansion and Macronix devices. The flash variants that have been tested are as follows:
