Why MAX10 always boot from CFM0 when power up? - Why MAX10 always boot from CFM0 when power up? There are 2 different image in Max10(10M08SAE). Pin of CONFIG_SEL , 10-KΩ pull-down. I have set config_sel_overwrite=1, config_sel= 1( When I trigger FPGA to reconfigure by DualBoot IP, it can boot from CFM1/2. ) After power up, I found config_sel_overwrite=0, config_sel= 0, and boot from CFM0. Why? Are they(config_sel_overwrite & config_sel ) saved in FLASH or register? I thought I can select the Boot Image by writing config_sel & config_sel_overwrite even in Power cycle of FPGA. Thanks.

Hi, If you are using the Dual Boot IP, then you will need to write a state machine to on your image0 so that after setting the config_sel_overwrite and config_sel then you only you trigger the reconfigure through the IP. If you would like to boot to Image1 after power cycle then you will need to connect CONFIG_SEL pin to 10-KΩ pull-up.
