Hi Sir, Any update on this? Thank You Replies: Re: MAX10 Dual Boot UFM booting problem. Hi, If the UFM size is not enough. Then what you can do is using the CFM only. Thats the only way. Thank You.

Have you followed our user guide to implement that?" => yes. i try to design with AN741. but firmware is too big to implement in UFM. UFM is 64k byte. but my code is 250k byte. and the code I wrote is the same as the code of AN741. Replies: Re: MAX10 Dual Boot UFM booting problem. Hi, May i know where do you get the RSU design?
