max10 remote system update nios with uart

hii

do you have a design guide that explains how to do RSU without the need of a nios 2 processor

lets say i want to write my own vhdl code to perform the rsu , from what i understand

1- i need to be able to read and write the cfm sections in order to write the my image into cfm0 and cfm1/2 in dual compressed mode

2- trigger the fpga in order to read the new image from cfm1/2 and configure the fpga logic by hardware or software

i would like to know if there an application note that explains how to do RSU manually without the help of nios

3- another question if i configure the nios v processor to boot from qspi does it take up from the logic elements ?
