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.
