Hi NXP community, I'm working with the MIMXRT595. I saw in the Reference Manual that it mentions a high-speed boot mode. How should I configure or start it? During testing, I found that the maximum speed for SPI Serial Boot cannot exceed 24MHz.
Hi @wx1 ,
Thank you so much for your interest in our products and for using our community.
Regarding your question, to enable high-speed boot mode, we need to burn fuse BOOT_CLK_SPEED. But the latest RM has little description about it and does not contain the fuse item. I have created an internal ticket for it, If there is any feedback, I will inform you promptly.
Take care if the high-speed boot mode is enabled, the power-on voltage need to meet the required.
Best Regards
