I need to have the bootloader in the boot partitions of emmc. Initially it should boot from boot0 (boot partition 1) and write to boot1 (boot partition 2).The next time it should boot from boot1 and update to boot0. How can I handle this in the uuu script?</P><P>Really appreciate any help.</P><P>Thanks !</P> Thu, 15 Dec 2022 21:24:58 GMT https://community.nxp.com/t5/i-MX-Processors/imx8mn-boot-from-boot0-and-write-to-boot1/m-p/1570732#M198829 liza_mary 2022-12-15T21:24:58Z https://community.nxp.com/t5/i-MX-Processors/imx8mn-boot-from-boot0-and-write-to-boot1/m-p/1572150#M198970 <P>The uuu can't support such function, this needs you change the uboot source code and uuu code.We don't have such solution at present.</P> Tue, 20 Dec 2022 00:37:46 GMT https://community.nxp.com/t5/i-MX-Processors/imx8mn-boot-from-boot0-and-write-to-boot1/m-p/1572150#M198970 Zhiming_Liu 2022-12-20T00:37:46Z https://community.nxp.com/t5/i-MX-Processors/imx8mn-boot-from-boot0-and-write-to-boot1/m-p/1572614#M199037 <P>Thanks for your reply!</P><P>I think, I managed to write to both boot partitions.
