flexSPI_B1外接QSPI Nor Flash启动问题

[cams]

Hi，在我的项目应用中采用i.mxRT1062，由于flexSPI_A用做了其它复用端口，只能用flexSPI_B1作为外部QSPI Nor Flash存储接口，QSPI Nor Flash 采用GigaDevice GD25Q54C，MDK 的 led_blinky 中如何设置在Nor Flash 中进行调试以及Flash Loader如何设置？，其与flexSPI_A1设置有何不同？谢谢！

Hi rayandy fan ,

非常感谢使用NXP产品，很高兴为你提供技术支持！
1.硬件连接参考参考手册中的Table 8-1. ROM Bootloader Peripheral PinMux。
2. 修改工程XIP文件夹内的evkbimxrt1060_flexspi_nor_config.c以匹配GD25Q54C。
3. 根据考参考手册中的Table 8-10. Fuse definition for Serial NOR over FlexSPI，调整Fuse中的BOOT_CFG值或BOOT 引脚状态来匹配GD25Q54C。
3. 至于你说的设置Flash Loader，不太明白你的意思，请再解释一下。

非常感谢您的答复！我现在有个问题，根据rt1060参考手册ROM APIs特殊说明，bootROM是不是只允许从flexSPI1 A端口启动，其它flexSPI 端口不支持（比如flexSPI1 B、flexSPI2）? 所以我通过flexSPI1 B端口外接QSPI Nor Flash是否就不能通过bootROM启动？

Hi rayandy fan ,

感谢回复。
FlexSPI ROM API不代表ROOM boot启动有这方面的限制，但说实话，我也不能100%确定的，所以我的建议是你可以考虑Table 8-1. ROM Bootloader Peripheral PinMux给出的Secondary option连接方式，如果跟你其他的硬件电路部分不冲突的话。
