What is the state of GPIOs of Max10 during bootup? Are they high? How much time is required to boot Max10 from internal UFM/CFM?

My IOs are pulled down in logic. But when I bootup the Max10 I see a pulse on these IOs ? What is the state of output IOs during the bootup? Can I reduce this time? ​

Hi Haseeb,

 

The IO is in tri-state mode during configuration.

https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/max-10/ug_m10_config.pdf (Page 28)

 

The configuration time cannot be reduced and it is depending on the size of bitstream.

 

Thank You
